DIY Bicycle Front (And Rear) Dash Cam, Part 1

You know dashcams create a record of evidence. Surprisingly, they are also visible to nearby drivers, and become a deterrent just by being in plain sight.


I have been using inexpensive action cameras (i.e. GoPro clones) for years as dashcams on my urban commute and cargo ebikes. Going DIY, I get much higher video quality and spend a lot less money. Once you figure out how to set them up, its an easy process.

I started doing this after I was run down (a T-bone SMIDSY) by a negligent driver in 2017. The police report worked hard to blame the victim (me) for traveling at low speed (about 15 mph in a 40 zone), with three headlights on, in the designated on-road bike lane. I even made eye contact with the driver while she stopped before pulling out and into me. I found out the hard way the driver was looking through me, not at me.

What the hell is a SMIDSY?

At least the police report conceded the driver was the cause of the accident – and tried to take it back a bit by stating that the safe speed for a bicycle “may have been 3 mph”. Yes, thats right… three.

Unfortunately, experienced urban cyclists will recognize the problem. Motorists often get every benefit of the doubt when they run down a cyclist, regardless of the consequences of the motorist’s inattention. I was carted off in an ambulance.

Cyclists Need an Irrefutable Witness

Over the years, I have learned a few things about what kind of camera is well suited to this job, how to best install it, and how to configure it so it is as easy as possible to use on a routine basis. During a recent online discussion on the subject, it occurred to me this would be a good topic to lay out for people all in one piece.

Lets make a centralized parts list right off the bat, so its easy to come back to.  We'll get into what each item is and why it is on the list further on:

What About External Perception?

As alluded to in the lede above, having visible cameras does more than just preserve an evidence record (I tell people who ask about them – only half jokingly – they are there to tell the police who killed me).

My v1.0 mounting of my front camera on my white Bullitt. This is the best, most functional layout of the light, (placing it up high) and the camera.

Something I have experienced has been echoed to me informally by other cyclists: People treat them differently when the camera is there, blinking its little red “I’m on” light. Drivers seem to behave with a bit more civility. Is this a scientific observation? Nope. Is it a universal benefit? Nope. But it does look as if, when people know that Little Brother is watching, they are less inclined to brush you back or run you off the road.

Camera mounting v2.0 happened not to get better performance out of the camera, or the front headlight, but to make the camera more plainly visible to nearby drivers.

Once I realized my own perception of that phenomenon was not unique, I decided to supplement front cameras with a second, rear-facing one. Yes I want to get video of an oncoming vehicle that may do a bad thing. But even more so, I want that driver to maybe see the camera and … sober up a little?

Worth mentioning: Cameras like this have been used for years by motorcyclists, and I think motorists have grown somewhat used to them as a result. I have yet to see a volatile reaction by anyone getting mad I am recording them as they go by.

However, I do respect others’ privacy, and I will not be showing any stills taken from my cameras that show clear license plate views (which is the high standard we are going for here).

What About Turnkey Products?

Turnkey solutions exist for cyclists right now. Perhaps the original is the Cycliq Fly. One look at the price for front and rear cameras may give you pause. But if protection is afforded, price is secondary.

Instead, when evaluating them dig a little deeper at the camera resolution. The front camera provides a best resolution of 4K @ 24 fps, with 6-axis electronic image stabilization. That is pretty good but – in 2023 – unremarkable. The rear Fly6 on the other hand gives you a 135-degree view at a resolution of either FHD (1080p at 30fps) or HD (720p at 60fps). Their rear camera provides no mechanical or electronic image stabilization.

The Cycliq product also incorporates an app, and each version also incorporates a light.

Garmin makes a bike camera system as well. Its rear-facing Varia is a combination of rear light, camera and actual radar. The radar senses an approaching auto and warns you of its approach. Rider discussions I have seen report the radar really works. Insofar as the camera is concerned, its best resolution is 1080P @ 30 fps. There is no front camera option.

Bottom line: A turnkey solution for both front and rear is going to cost rather a lot of money. It may or may not provide a video solution that allows resolution and stability that will capture a legible license plate. I consider that license plate essential as it may belong to a vehicle that left the scene long before you are carted off in an ambulance.

In my own personal experience, I have tested the video resolutions and frame rates described above on cameras and consider them failures in the license plate reading game. They will be fine for capturing what happened, but if the car leaves the scene, law enforcement officials won’t be able to identify the vehicle from the plate number.

What About DIY?

It turns out ‘generic’ action cameras have all the features you need to make a dashcam. You just have to know how to set it up, which is not difficult. They will give you a highly detailed, electronically-stabilized screen resolution (you cannot take stabilization in all resolutions for granted and have to carefully review camera specs to confirm this).

High up is where a front camera usually goes on my bikes. Thanks to the 170 degree lens angle on my preferred camera, putting it a bit over to one side or the other on the bars is a non issue.

I have bought a number of cameras over the years. Some have been expensive (GoPro), some have been really cheap (low end Chinese GoPro clones) and some not so cheap. I will skip any further mention of that learning experience and just jump right to the one that works best for me now – in 2023.

The Akaso V50X Action Camera

  • In 2023 as I write this, this model has been around for awhile. I bought my first one in early 2021. So it has a feature set that is not state-of-the-art.
The camera, shown inside its waterproof scuba box, mounted with the front mount in our parts list. The red knob kajigger is some extra added bling. The wire sticking out? We’ll cover that in Part 2.
  • In 2023 as I write this, this model has been around for awhile. That means it is not a premium priced product. I bought my most recent two on sale for US$79.99 each. MSRP is US$99.99.
  • The camera uses a native 4k resolution with a native 30fps frame rate. There are other rates available going up to 60 fps, but in side-by-side testing, the 4k/30fps with image stabilization enabled gives the best license plate readings. Note I said ‘native’ above. That means there is no on-board interpolation to up- or down-rate the image. Since ‘interpolation’ means ‘adjustment’ and ‘approximation’, native processing modes should give the camera’s cleanest end result.
  • No proprietary software is needed to play or process the video. I use the movie software included with Microsoft Windows 10 to view and edit the files.
  • Electronic Image Stabilization (EIS) differs in effectiveness from brand to brand. EIS on the V50X is very effective. I almost can’t see how it could work better. I have tested it on potholes and curbs and the video remains steady.
  • Settings are available to loop record, which is a critical feature for a dashcam application. The camera records in short time-loop intervals (shorter is better… we’ll discuss why later), then starts another file. When the SD Card storage fills up, it records over the oldest files, so you never have to flush it clean when it fills up.
  • Settings are available to turn the camera on as soon as it receives power. A driving mode makes camera startup and recording automatic, although I prefer not to use it.
  • Out of the box, the V50x comes with a zillion accessories. Way more than you will ever use. The one accessory that is critical is included: the waterproof scuba box (not needed for waterproofing… we’ll get into that later). You can buy a second box cheap on Amazon to share a camera across multiple bikes.
  • Its got a slightly bigger battery than other models in the Akaso line (which I also own). We’ll discuss a setup that bypasses the battery later.
  • Having had a V50x in service since 2021, and other Akaso cameras since before then, I have found the brand produces a reliable product.

A shorter version of the above is:
the V50x is cheap, durable and does everything you need for a bicycle dashcam.

SanDisk Extreme Pro Micro SD Card

You need this for the camera to store its video files. No camera comes with them and they have to be purchased separately. With a 200 mbps write speed, this is the fastest card you can get your hands on right now. You need big write speed to support the 4k/30fps mode on the camera. And since Micro SD cards are cheap, a relatively gigantic 128GB card is only US$20.

According to the instruction manual, the V50x camera only officially supports 64GB cards, but the manual also says some 128GB cards will work. This one works. I use them due to the fast write speed, not the storage size.

The Front Mount

I’ve tried a few mounts and, once I settled on this one, have stuck with it for years across several bikes. It is all alloy, no plastic, and mounts rock solid on the bars. Over time it does not loosen up, and keeps the camera in place regardless of bumps and bonks as I go down the road.

It does rotate on its horizontal axis by design, but there is a strong detent in place so it can’t happen accidentally. This rotation lets you put the same mount at different positions on a swept-back bar and it still points straight forward.

The Rear Mount

I have only recently started doing rear cameras and this mount was exactly what I needed to make it happen. It is all aluminum with stainless bolts, and mounts solidly to the saddle rails. It doesn’t move over time. Its easy to mount the camera to its GoPro-compatible mount.

With this seat rail mount, the camera in its waterproof case tucks right in under the saddle where you’ll never know its there.

This mount does make it necessary to mount the camera upside-down, but all of the video-editing software I have ever used – and I always use something simple and free with minimal features – allows you to easily flip the video right side up. The time stamp onscreen will be upside down but we aren’t trying to be Cecil B. DeMille here … its just a dashcam video.

The saddle mount positions the camera so it sits with plenty of room to clear the Kinekt and Thudbuster seatposts I have used it with.

The (Optional) Power Pack

There are a few ways to power your DIY dashcam solution. One way is to just use the in-camera battery. Another is to run a little USB cable from the camera to your ebike display’s USB port. That will give you a constant power supply that never runs out. If your display does not have a USB port available, the next best step is to fudge it and use a USB power bank. I have found it is much more convenient to use a big power bank and charge it, say, once weekly, than it is to use the in-camera battery that is going to need recharging after every single ride. I’m including links to two different – and big – power banks.

I do not use power banks this big to run just my camera. These banks have three USB outlets. I use all three – two to power my LED COB light banks and one to power one of my two cameras. I have a USB display powering the other. So for a more normal bike, one such power bank could power two cameras no problem for a week of long, daily commutes. A much smaller power bank would probably be fine, too; especially if handlebar bag space is at a premium.

I am linking to one Anker power pack that is a top quality item and priced accordingly. I’m also linking to one much cheaper and – on paper at least – is just as capable and 1/3 the price. I can’t be sure if it is as reliable as the Anker but for twenty bucks versus almost seventy… I figured it was worth a shot. I have only been using it for a few weeks so far.

Misc USB Cables

There are a half-dozen different ways to wire these things up. If you are doing a direct wire to a power bank or display on a rear camera, a long-ish USB cable with a right-angle plug at the camera side is a good choice. If doing a front camera mounted to the bars and tied to the USB plug on your handlebar display, you can get away with using the short freebie cable that comes with the camera. If things are lined up just wrong on your display, you may want to use a short 45-degree USB extension. We’ll go over a few variations …

… when we tackle camera installation and configuration in the next installment. 🙂

Make Your Own Cheap, Hard Shell Panniers – Part 2: Assembly

We went over the parts list in Part 1, now its time to get down to business and make some panniers.

This is part 2 in a two-part series.  If you haven't done so already, check out Part 1.

So Lets Build It Already!

Before you drill a single hole, or make a single cut, you need to take something into account that isn’t immediately obvious.

Measure For Heel Clearance

This is something you have probably taken for granted but will recognize instantly when your attention is called to it: Panniers have a diagonal cutout in their lower forward portion. The reason for this is so your heels clear the pannier when you are on the back side of your pedal stroke. A DIY pannier like a trash can does not have this cutout.

Fortunately, I knew to measure for this in advance. I was surprised when I saw how far back I had to go. Luckily the can slopes into a more narrow profile at the bottom, so half the work is already done for us.

How do you measure for heel clearance? The fact my bike shoes cleat into my pedals made that job easier: My foot position is always fixed in one spot. I just clicked my shoe into the cleat and rotated it.

I took the picture for Figure 1 below after installation. But I did the actual work by holding the can up against the rack with one hand, grabbing the shoe with the other and moving the can back until the shoe cleared.

Then I eyeballed the can relative to the frame to decide what spot was the final location: The front edge of the can is lined up right alongside the back edge of the bike frame.

NOTE: I eyeballed everything and measured almost nothing on this project. You will see some wavy lines as a result. It worked out, but you should be a little more careful than I was.

Figure 1: There is not a lot of clearance here, but you don’t need even this much. If it clears at all you will never know the panniers are back there while riding.

Measure the flat part of the top inside of the can

This will tell us how much flat bar to cut for the mounting plate. The hooks and bungie cord mounts bolt into this. If you don’t use a plate and just drill holes in the plastic can, thats not going to be anywhere near as strong, which is not something you want on a big bucket holding things for you on a bouncy road.

Figure 2: Here is what the plate will look like, after installation. The holes are off-center thanks to what we learned measuring for heel clearance.

You want the plate to extend only across the flat portion of the can’s side, stopping where the can starts to curve at either end. This gives you maximum contact without affecting the molding and shape of the can.

Cut the aluminum flat bar to match this measurement

For this can, it turned out a 10″ length was about right. You should confirm this measurement matches whatever can it is you are using. Even if you are using the same Rubbermaid wastebasket.

Decide where the hooks are going to go on the rack

I just manually placed them as far apart as I could, where each hook ends up jammed against a rack cross-support. That config for the hooks means once the pannier is assembled, it can not slide forward or backward on the rack.

Mark the mounting plate with the J-hooks’ bolt holes.

NOTE: This part is a LOT easier to do if you take the rack off the bike. Since I had an identical rack waiting to be installed on a new bike, I used that.

With the mounting plate attached to the outside of the can with blue painter’s tape at its proper fore/aft position, line the plate up to the hooks, which are still sitting in their mounting position on the rack. Mark the holes to drill in the plate thru the hook holes with a Sharpie. Remove the plate from the can.

We only need to go through this measurement process once, since the second pannier is a mirror image of the first one.

Drill the marked holes into the two mounting plates

Once those four marked holes are drilled on your first plate, line it up atop the the second, uncut one. Drill thru the existing holes, down into the second plate. Now we have two plates with matching holes. You just need to flip over the second one so it works on the other side.

Figure 3: The two plates are clamped together and the holes in the first are being drilled down thru into the second. The topmost hole hasn’t been drilled-through yet.

I used strong clamps to hold the two plates precisely, firmly together. As noted, I used M5 bolts throughout this project, so use an M5-sized drill bit.

Chamfer (partially countersink) all of the holes

As seen in Figure 2, I am going for a flat profile on the mounting plate, inside the can. To get that, I am using countersunk M5 socket head bolts, and larger M8 washers that are wider than the bolt hole, but narrower than the full width of the socket cap. The last ingredient in achieving this flush fit is to chamfer a bit of the bolt hole. That gives the beginnings of a full countersunk hole (since we are using a 1/8″ plate, we don’t have enough material to do a full countersink). Use an M6-sized bit to drill in the already-made M5 holes just a hair to create this effect. You can set the drill to reverse direction to just kind of grind in the chamfer (properly drilling it is very easy to overdo).

Drill the mounting plate holes through the can

Position the mounting plate on the outside of the can so it is lined up where it is supposed to be installed. When you do this, since the plate is on the outside of the can, but it will be installed on the inside, make sure you have the plate oriented correctly (i.e. not backwards or upside down).

Figure 4: I wrote myself a note to remind me which side should be installed up against the can on the right-side pannier. These bolts are just stuck thru already drilled holes to hold the plate in position while I drill the two outer bungee mount holes.

Again: Make sure you don’t reverse the position of the plate and get the holes backwards. I made this mistake on my first pannier, but fortunately that meant I could just flip it around use it on the other side… so long as I didn’t screw up on the second one and create two right-side panniers.

Do the bungee mount holes

I am describing this step out of order, as it should be done at the same time as the J-hook holes are drilled, above. I did things differently on my first installation, and this step actually came later and needed a complete disassembly to make it happen.

Figure 5: My original bungee installation re-used the lower hook hole for the bungee P-clamp. Just for starters the knots got in the way of the rack stays. After some use I came up with a better way to do this.

So the original installation used four holes in the mounting plate, and the final version uses six, with the two P-clamp holes being far outboard from the hooks, and more or less at the same vertical level as the lower J-hook holes.

This mounting position gives us perfect cable tension. It also leaves lots of mounting plate around the bolt hole so the washers on the outside are backed fully by the mounting plate on the inside.

Figure 6: Bungee v2.0 works MUCH better. Uniform length thanks to no knots or uneven cable cut. Thinner cord vs. the humongous leftovers I used from my parts pile. Enough tension to do the job without worrying me about long term damage to the flexible rubbery can.

Bolt everything together

OK so pretend all that stuff you see in Figures 2, 5 and 6 hasn’t happened yet. But its about to. We’ve drilled all our holes and now we bolt everything together.

Our J-hooks all use M5 x 16mm countersunk hex caps, with an M8 washer on the inside, bolt sticking out. Outside, we have the Jandd pannier hook, directly against the plastic. On top of that goes an M5 nylock nut (if you want to use a flat washer under the nylock, there are enough threads to spare to do that).

The two bungee mounts use identical bolts and washers, facing inside-out, with a steel M5 fender washer on the other side, up against the plastic. On top of the washer is the 1/2″ P-clamp, and on top of the P-clamp is another M5 nylock.

Assemble all of the bolts loosely

Since we are talking about nylocks, just screw them down by hand until the nylon lock ring stops you from using your fingers to further tighten it.

Tighten down the hooks first

Once all of the 6 bolts are hand snugged (they will actually be quite loose), tighten only the top two bolts of each hook. But not quite fully. The screw holes on the hooks are sized a bit large so you want to be able to re-align the hooks as you go along. Once you truly clamp to the plastic on the top two bolts, do the same for the bottom two, keeping the hooks properly parallel with your fingertips if they shift around.

Now do the bungee mounts

Pretty straightforward here. Tighten down while keeping the P clamps at a 45-degree angle as shown in Figure 6. When the bolts are fully tight they lock the P-clamp in position.

Figure 7: With everything bolted up, there are two ways to route the (red) bungee strap. I decided to use the right side routing as it lets the pannier sit directly against the rack stays… which will matter once you take in how the cinch straps work.

Add the cinch strap

Anyone who knows old school pannier bungee strap mounts knows I left out a step: There is no lower strap to capture the bungee and keep the pannier from flapping around, as the bike moves down the road.

Figure 8: These cinch straps are easy-on and easy-off, taking just a second or three to release or reattach. They are interwoven inside around the outside of the rack, inside the bungees and back outside the inside forward rack stay… so they can’t slip down.

This omission was intentional. Having a lot of cinch straps in a box in my shop, I opted to use them to lock the pannier down onto the rack. Removing the strap only takes a second, and the stability it provides works so well it not only never rattles, I could probably ride a singletrack trail without any worries about it moving.

Nest in the second can

We’re finally going to see why we’ve done that countersink stuff. Lets show it in a sequence of pictures; left-to-right:

So thats easy enough to understand. We kept the mounting plate flat so it would not interfere with the nesting of the cans. What is the point of that?

  • A double-thick pannier is much stronger, and loses all semblance of wobbliness. Stronger means stronger all around and includes the ability to take hits, lean the bike on things etc.
  • The interior is completely un-holey and waterproof.
  • The insert is easily removable. Once home from the shops, just pick up the inner can and walk it inside to unload.
  • When nesting the two cans, you can easily slip in a sheet that makes a lid for the pannier, with the 48″ flat bungee being an easy-apply band around it to secure the lid. The fact that the sheet is snuggled in between the nested cans makes it an attached, integral piece of the pannier, not a potential UFO if a strap comes loose.
  • That second can beefing up the operation makes the pannier system a substantial piece of kit… and costs a whole US$8 per side to add in.

Finish it off: Put on a lid

The very first idea I had for this job was the easiest to manage. It cost virtually nothing and was easy-peasy. I took a full size garbage bag and folded it into a 20″ x 17″ square.

Figure 9: Pannier Lid v1.0 – a simple folded garbage bag. It worked great!

The folded bag worked extremely well. It was easy to manipulate and rendered the panniers completely waterproof in rain and wind. The trouble was… it looked like I was using garbage bags for a lid. I wanted something that looked better. and so we have Pannier Lid v2.0:

I splurged on Amazon and spent $27 for some vinyl fake leather, ordinarily used for furniture re-upholstery. I used more material than I needed so I have the option of expanding the lid should I stuff things into the pannier that stick up.

You can see in one picture above how I have a second sheet with folded corners on a workbench behind the bike. That is the segment slipped in between the two cans as they are nested together.

Originally I had plans to do a proper measurement of just how much excess material I wanted to use, cut out in a pattern, where there was just the right amount and shape of fabric to stuff down in between the two cans for a fold-free fit all around. The right measurements on the rest would let me use nice hospital corners to fold up nice and neat on the outside, too.

I ended up just cutting a single sheet, 24″ wide in a straight cut off of the big fabric sheet I received. Then I cut that in half on the long side, leaving me with two sheets measuring 24″ wide by 27.5″ long. That 27.5″ side is the one that gets triangle-folded and tucked in between the two cans.

Because there is so much extra material for expansion, folding it up on the outside is a little less tidy. BUT in exchange for that the lid can expand considerably should I need it to.

And that, as they say, is that. Or is it?

Job done. I haven’t decided if I am going to use these for Bullitt II as originally intended, or leave them on this bike and buy four more cans and do another set for the other bike when the frame finally arrives later this month. Since its a white frame, I’d buy a white set of cans, but for almost everything else on the build sheet I have all the parts to do another set. Having a set to use as a reference, I can probably get the entire job job done in an afternoon.

Make Your Own Cheap, Hard Shell Panniers – Part 1: Parts

Commercial products are available but are priced at US$300 for a pair. This alternative offers more space for minimal cost, needs only a few simple tools and can even be assembled in a few minutes.

This is Part 1 of a two-part series.  If you are looking for Part 2 it is here.


I need some big panniers for the upcoming Bullitt II. I use them now on my current Bullitt as overflow when I fill my cargo bay on a big shopping run.

While I was pannier shopping, I came across a hardshell pannier called the Coolcave, offered by Specialized. It looks like a very neat product, especially when paired with its lid pack, sold separately, that takes its capacity up to 25L. Unfortunately, each pannier is priced at US$80, a lid pack adds another US$70. So US$300 for two panniers. For a cargo bucket in a middling size, that pricing is well past my pain threshold.

While I was looking at them online, I couldn’t help but notice the Coolcave looks an awful lot like a small trash can, right down to the molded-in feet that let you sit it on the ground.


You can see where I’m going with this already, right? How tough can it be to get some nice clean new trash cans and make panniers? Especially since I have a lot of the parts in the garage already, and all the tools I could need to make this project happen.

As I began looking around for the parts I needed, I found I am by no means the first person who has had this idea. Jandd Mountaineering has their Tidy Cat bucket kit. Sellwood Designs has their own bucket and bucket kit available at I am sure there are many more out there. If you are considering a DIY approach, all you need to know is almost any container that isn’t round can be made into a pannier.

Lets get started.

Project Pan-Yay Begins

Let me lay out the ‘final’ parts list on the panniers I ended up making. These are the parts that made the final cut. Further on I’ll comment on some alternatives that would have worked out great, but inflated the cost too much. This build is meant to be budget-minded.

Parts List

  1. Rubbermaid Commercial Products 28-qt wastebasket (US$31.61 for four)

    28 quarts in Imperialist units works out to 26.5 liters each. Why are we buying four instead of two? I’ll get to that later. These commercial wastebaskets are meant to take a beating. They are soft and flexible, yet sturdy. They can be put into a freezer that goes down below freezing temps (I know of a lab that uses them to freeze water into great big ice blocks). They nest inside of one another snugly.
  2. Two strips of aluminum flat bar (US$6.00 total)

    I used a strip 1.5″ (38mm) wide and cut each to 10″ (254mm) long. Width was dictated by the bolts used for the hooks, and length is the flat width of the trash can. Cost is based on 20″ of an 8-foot bar purchased at the hardware store for about US$28 – that I already had some of in my garage.
  3. Jandd Mountaineering stainless steel pannier hooks (US$18.40 for four)

    These hooks are dirt cheap, easy to install, beefy and durable.
  4. 24″ bungee cords (US$5.16 for two)

    Using bungees to fasten a pannier is old school, like the Jandd hooks. However using one commercially-available, non-DIY cord per side isn’t. Its a nice hack.
  5. 48″ bungee cords (US$7.96 for two)
    I use these flat bungee cords to secure my waterproof, expandable ‘cloth’ lid. It works faster than a traditional buckled pannier flap, and is more easily expandable.
  6. 1/2″ vinyl-lined P-Clamps (US$2.00 for four)

    These are used for mounting the 24″ bungees. They’re available at any local hardware store. Mine were in a cubbyhole in my garage already.
  7. 2″ x 48″ Hook and Loop Cinch Strap (US$8.00 for two)
    I have chosen these 48″ straps as they should be right for one strap to fully encircle the pannier and thread thru the rack stays – I am using straps to bolster the j-hook-and-bungee pannier mounting. They are easy to remove, easy to attach and make the panniers so solid to the rack I could ride with them on a singletrack trail and they’d stay put (pro tip: Use a black Sharpie to make the garish logo invisible).
  8. Two yards of fake leather vinyl sheeting (US$26.99)
    Let me say right off I first used two folded-over garbage bags for lids with my 48″ bungees and they worked fine. Using this waterproof vinyl is a purely cosmetic choice. The 2 yards you get is about 3 times what you need.
  9. Various Stainless Steel Nuts and Bolts (US$20.00 total)
    I used M5 bolts with countersunk heads, oversized M8 washers and M5 nylock nuts. This is a little weird but mounting the bolts so they go inside-out gave me a completely flat surface inside the outer can… but I’m getting ahead of myself mentioning that so I will stop now. I am ballparking the cost here, which you can reduce by quite a bit by using zinc-coated steel parts instead of stainless. I will list the specific nuts, bolts and washers in each part of the assembly instructions.

Total Project Cost

Add up all of the above and you come up with $126.12. Which sounds like a lot for two trash cans, but pretty good versus retail price on two 26.5L-each, waterproof, hard shell panniers – if you could find them for sale at all.

You can cut costs here. Don’t do the nested cans and use two instead of four. Forget about the vinyl and stick to the folded trash bags. Just those two things knock off US$43 from the project cost. Do without the bungees for the lid and you’ve now removed just over US$50. Find a couple things in your garage to use instead of buy and you knock off even more.

Alternate Parts

Trash Bags

Lets get this one out of the way immediately. If you want to cheaply create a waterproof liner for your pannier, then the 7-10 gallon trash bags that are sold everywhere as a direct fit to these trash cans are an obvious solution.

Savvy cyclists know a trash bag makes ANY cloth pannier instantly waterproof. The use of a bag as a can liner can also take the place of a lid. Especially if closed off with something like a reusable OneWrap tie, or a small cinch strap.

Next, when setting up the lid, before I received the faux leather I eventually used, I simply took a full sized trash bag, re-folded into an even-ish square. Then on the rack-side, I tucked it in between the two layered-together cans so it becomes semi-permanently attached (only coming off if I separate the nested cans). This creates a square flap with overlap that I can easily flip off and back on again, using the 48″ flat bungee strap.

On my first day of use, it was raining, so I had to have a lid. The folded trash bag worked perfectly. the only knock against it was cosmetic: I was obviously using a trash bag.

Ortlieb Mounting Hardware

While I was researching my options for the build, I came across this page at Campfire Cycling that lists a wide range of in-stock Ortlieb replacement parts. A complete mounting solution can be pieced together.

  • 4-hole QL1 long rail
  • QL1 top hooks with handle
  • QL 2.1 lower rail
  • QL 2.1 lower hook

You are mixing mount versions top vs. bottom, but thats not a problem. With shipping the cost is about US$80 to ship 2 panniers worth of parts to me in California.

Thats top-quality equipment, but I was not ready to spend that much on a concept I was not 100% certain was workable yet.

Vincita Mounting Hardware

I actually purchased this and intended to use it as my go-to solution on the first build. Unfortunately the shipper reported the package lost, and I got a refund. Some time later a battered package finally showed up on my doorstep.

As such I had the opportunity to inspect the mounting kit, even if I didn’t use it. I had picked the 12mm kit and found it to be of very good quality, and definitely workable with my Axiom rack’s tubes. At less than US$13 per side it would have been an economical option as well. I’m not sure I would have wanted to use the lower mount on its own. I’m pretty sure I would have wanted to use the bungees as I ended up doing here.


We’ll get to that in the next part. This is a good spot to put in a break.

(e)Bike Tool Kit – The 2022 Edition

In the last few months, I’ve made a few changes to my standard on-bike tool kits. Lets take a look.

Things have changed a little since I originally wrote up my full size tool kit in late 2020, and my minimalist tool kit a couple weeks later. The changes are not big but when you are talking about risking your ride turning into a walk – especially in rough, remote terrain – its worth bringing up the things I have changed.

The Core Kit Items

Unless noted otherwise, the changes here are the same for both my full and minimalist kits. Lets run down the main players on the small kit first, so you don’t have to go and refer to another article to get the complete contents.

The Patch Kit

As I noted in 2020, Rema Tip Top cold-vulcanizing patches have been the gold standard for decades. And that is before I started using them in the 1970’s. They are essentially unchanged today. If you just want to buy what you need, then the Rema Large Touring Kit is the way to go. At present its a whopping US$7.15. However, I do it a little differently. I take an empty Costco pill bottle with its locking lid, and then I add a slew of my own patches, along with a snip of special sandpaper and a much larger tube of cold-vulcanizing goo. This gives me a more capable patch kit in a better, stronger container. It is not the no-brainer that just buying the pre-made kit is, though.

The Tire Levers

As was true in 2020 so it stays true now: After trying many alternatives, the Park TL-6.2 tire levers are the ticket. You can see them rubber-banded to a patch kit bottle above. They’re superior because they are metal, with a sturdy-enough-to-withstand-use plastic coating.

A Tire Patch

The Park TB-2 Tire Boot remains the standard and one is always found in my patch kit just in case. This is just a great big gooey patch meant to be applied to the tire and not the tube. You use one of these if you have some kind of major slit in the tire casing that gives it the tire equivalent of a hernia.

Hex Wrenches

A stubby set made by Bondhus metric wrenches is in most of my kits (some of the bigger ones get a long set). These are made of high quality tool steel and inexpensive. You don’t need a whole set so if you want to shave weight or save space, you can buy these individually or just buy a set and include only what you need. However an extra piece of steel can be a handy pry bar. You never know…

A Pocket Knife

A pocket knife is one of those just-in-case items that has no specific job, but can come in REAL handy in so many ways. A Kershaw Shuffle is a good quality, inexpensive folder that incorporates flat and Phillips screwdriver bits. A.G. Russell’s Featherlite One Hand Knife is lightweight and handy for only about US$35, and their ‘Simple 3″ Lockback‘ is a bit less than half that price. Or how about a Slidewinder for ten bucks? Substitute in a multi tool for greater functionality (I saw a Leatherman Bolster on sale in a local Costco recently for only $39.95), but that is expensive and could make your tool bag a bit crowded.

Needlenose Pliers

I carry these outside my toolkit, usually somewhere I can grab quickly. The idea is if you hear that awful hiss-hiss-hiss sound as your tire rotates around a nail or similar, you stop the bike, jump off, grab the pliers which are in a quick-grab place and pull out the offending nail. Speed counts on this particularly if you have tire sealant like FlatOut waiting to do its job once the nail is removed and you spin the tire.

Its entirely possible the needlenose pliers can be done without depending on how you feel about the first item on my New Stuff list below.

New Stuff

Knipex Wrench/Pliers

7 1/4″ (180mm) size is my favorite for a bike tool pouch, although I also have the two smaller sizes (150mm and 125mm). The 180’s are ideal in my opinion. Small enough to use on a rack bolt, big enough to use on a pedal, or even an axle bolt.

These tools are spoken of in hushed tones by the folks who have been turned onto them, and I’m no exception. Think of them as a kind of super Channel Lock style of pliers, except they are optimized so you have much finer graduations in your ‘channel’ widths, the jaws always stay perfectly parallel and you can really clamp the bejesus out of these things, so much so they can be used like an adjustable, open ended crescent wrench. A 10″ / 250mm set lives permanently in my car and is great for bolting stuff like trailer hitch bits down tight.

This tool takes up the same space as the former adjustable crescent wrench and is more usable since it is a pair of strong pliers as much as it is a wrench.

Be warned, though. The little buggers are freaking expensive. But if you are a tool geek, you’ll love them.

A T25 Torx Wrench

Over time, the T25 Torx wrench has gone from something only Magura used on their brakes to a sort of alternate standard among manufacturers. Particularly when it comes to brake rotor bolts.

My brakes, brake rotors and now my seatpost use a Torx T25.

As much as I hate to admit it, the T25 is a better tool socket than a simple hex. Formerly only kept in my bigger tool kits, Since my Squeezy seatpost clamp also uses a T25 on my Apostate I’m officially carrying one in even my minimalist kits.

Battery Powered Pump

A couple of years ago I began championing the use of a portable air compressor that could be slightly modified to run off your existing ebike battery. I still have 4 or 5 of them, and I have never had one fail. However after reading some success stories, and my own research, I’m ready to say I have found a couple of models that are worth relying on.

About a year ago I started doing remote beach runs where there is no land access for miles along the route. You either climb up the beach cliffs and leave your bike, you go swimming, you turn back or you reach your destination. No one’s coming to get you because nobody is out there and your cell phone doesn’t work. Since my ride to the jumping off point was a few miles of paved shared-use path, followed by a bunch of deep sand and then more pavement home, I found I now needed a pump that could be used routinely and regularly rather than emergency-only. So I started looking at pumps and their reviews.

Out here, running out of juice would REALLY suck.

I found out pretty quick that many pumps advertise long life but when you dig into exactly what battery is inside, you find there’s not much there under the hood. Maybe 800 mah. For a pump that has to inflate two *fat* tires at least once and probably twice during the ride, AND have enough left over in case of emergency, I wanted some serious juice in the battery pack.

I decided to try out the CycPlus A8 pump, which had good reviews and published their battery spec. Not 500 or 800 mAh. 2500 mAh. Thats the biggest I could find in this class of small portable pump. What remained unanswered was whether the pump was reliable and whether or not – like lumens on headlights – the claimed battery capacity was remotely believable.

After a lot of use without any failures, I can say it has proven to be reliable. I literally can’t run the battery down in use on a given bike trip. The same has proven true with its companion model, the cheaper, lighter A7 model that trades the alloy pump casing for plastic.

The A7 is also narrower and longer. When I needed a pump for The Apostate, I wanted it to fit in my handlebar bag. I found I had to go with the A8. The A7 was too long to fit in my chosen handlebar bag. Not the biggest deal in the world. The A8 fits perfectly and the weight on the bars is not noticeable.

A7 on the left, A8 on the right. Comparative sizes are not quite to scale. Pic on the right is a little smaller than in reality compared to the A7.

Hockey Pucks

Most useful if you have a two-legged center-mount kickstand. A couple of regulation hockey pucks underneath your kickstand effectively puts the bike up in the air for service on either wheel. Ridiculously handy. Also if you are parking your fat bike on sand, the enlarged puck under your single kickstand leg can mean the difference between the bike staying up or sinking. Call this an optional item but if you can spare the space one or two pucks can be a huge convenience.

Hockey pucks in place let me easily lube my chain at the park rather than in a dingy old garage.

Gone But Not Forgotten

This is what was once in the toolkit but is now gone/replaced.


The Knipex pliers take the place of the adjustable crescent wrench.


Now that I have an on-demand air compressor, I can kiss goodbye this ancient, single-use technology. That means no more cartridges stashed everywhere I can find a place to fit another one, and no more cartridge head

A super cool, best-of-breed little part… but good riddance to antiquated, single-use co2 technology

Manual Backup Pump?

I’ve worked with the battery powered pumps listed above enough to finally cut the umbilical cord to my backup hand pumps… but if I can carry one without too much difficulty I will. This is one habit that is very hard to break for someone like me who is so invested in having redundant backups.

Needlenose pliers?

I think the Knipex will also do this job, but my US$9 needlenose pliers are often out in the open in a MOLLE slot outside one of my packs. I don’t know for sure if I want to hang a US$60 set of fancy German workmanship out in the same way. So long as I have the space I’ll keep the needlenose’s on the payroll. But really if we’re being a weight weenie, I can find a way to safely secure the Knipex’ and get rid of the pliers. Or attach a multi-tool to the exterior of a bag perhaps and make my emergency tire pliers handy thataway.

Well thats pretty much it for the tool kit. Not the most exciting topic… until something breaks and you’re sitting on a rock trying to fix it.

Ride on…

Tools List

Preparation is Everything?

In Planning, I opened by saying Preparation is Everything. With that said…

"Everyone has a plan until they get punched in the mouth."

-Iron Mike Tyson

Yeah. Lets talk about the reality check that is coming, once you actually ride the bike you just built. You learn whether what you thought would work actually does. More than likely, something will not work the way you’d like it to.

It won’t be a catastrophic problem, but this is a custom bike and you should expect a do-over or two to make it exactly what you want. This is how I wound up with the materiel and experience to write Musical Chainrings.

On that subject (bicycle gearing), over time that inevitable uncertainty has worked out in my favor. I know I am going to need some time in the saddle to figure out exactly how I want to gear any bike. I may also be surprised when I get a look at actual versus expected chain alignment. Thanks to Tyson’s Law, I have plenty of stock on hand to play around with and get it right.

You have to plan for and budget for this final step. Not necessarily for chainrings. There are a variety of typical culprits.

What Culprits?

There is a pretty common hit parade of things most likely to need a tweak. They all have something to do with the human/bike interface: How comfortable the bike is to you when you ride it.


Is their width comfortable? What about the angle? Your wrists feel OK after awhile? Need a rise on the bars? You’ll only be certain you got it right after riding the bike.

For the Apostate I put on a 760mm titanium flat bar. I have tried to use this very snazzy handlebar on a half-dozen bikes over the last few years, and was never happy with it, so it went back to the parts pile. Having had the Apostate on the road for a few months now, it looks like I finally found a permanent home for it.

My first ride on my Bullitt on February 21st, 2021. Look closely and you can see the same titanium handlebar on this bike; a few weeks later it came right back off. Again.

Handlebar stems

This is surprisingly important for rider comfort, and is perhaps the part I most often change after a new build hits the road. A longer or shorter stem can make a world of difference in comfort depending on what reach to the bars best fits you and your riding position (seat height relative to bar height also plays a role, so once again you need to be on the actual bike to understand what works best). A stem at a different angle can raise or lower the bars for a different improvement than changing the reach with stem length.

No matter what... do not use an adjustable riser stem.  The kind that has a hinge you can supposedly bolt down so its safe.  I know of two separate instances where they broke loose (thankfully I was not the rider).  Both under heavy braking.  Want to keep your teeth?  Use a fixed stem with a set angle to raise handlebar height.

For the Apostate I tried an 80mm stem with a 6 degree rise. Based on measurements from other bikes, I knew this was likely to work. But once again… you never know until you ride it.

Once I did, my posture naturally gravitated to holding the bars with my thumb and forefinger; not naturally planting my upper body weight on my entire palm. I needed a big change, and so I grabbed the biggest change I had: a much longer 120mm stem with a 45-degree rise. This raised the bars as much as was reasonably possible (about an inch and a half) while not really moving the bars forward much (which would increase my reach and make the problem worse).

I set aside these potential alternatives, just in case. I used the one on the far right.

After riding it for a week, it felt better, but I still had to think to put my hands down flat on the bar. I hadn’t gotten it quite right yet. I needed to reduce reach a bit while not affecting handlebar height.

Since I was pretty much at my best result on the stem length and handlebar height, my next step in fitment moved from the handlebars to the seatpost, where I knew I had a little room to maneuver, so to speak.

Worth noting: I could have stayed at the handlebars and changed the bar to one with a pullback of some kind. But I wanted to keep the bar flat and straight on this bike so…


If you are having reach or posture issues, one of the tools at your disposal is to change your seatpost. Some have a setback, where the saddle is mounted aft of the seatpost tube itself. Others have no setback and the rail clamps are directly over the tube. The difference moves your body forward or backward depending on what type you use.

I try to solve fitment issues with handlebars and stems. Changing seatpost setback is usually a last resort (and if you have a suspension seatpost, changing that expensive part is usually off the table as an option).

For the Apostate, a vintage 350mm Kalloy Uno came with the frame. This venerable post has been on the market for decades. It is a no frills, sturdy option. It turns out a 350mm post, with a bottom set near to matching the frame’s bottom edge (still well within its safety limits) was perfect for my pedal stroke. Winner winner chicken dinner.

Or not. As noted above, after riding it for a week I felt I still needed a small change, and it seemed like it would have to be a seatpost change.

The alternatives left were scooting the seat forward in the seatpost clamp (minding the limits scribed on the saddle), and changing the post to one with no setback. Since I was already at the forward limit of the saddle, that meant a different post with no setback. I did that in an over-the-top way, which moved this modification out of the ordinary and into the Afterword section below. We’ll discuss details there.

My original Kalloy seatpost had a ‘setback’ that moves the seat’s mount back behind the post’s center axis. The post I replaced it with has no setback.


You won’t know if it works until you sit on it and ride for awhile. But, you don’t have to start from scratch, either. What you like on another bike is liable to work again. I know that for bikes I pedal hard, I like narrower saddles. I knew I liked the WTB Volt (taken off of my Surly Big Fat Dummy) on my GG Smash enduro bike.

So I put on another Volt (I scored the much nicer Chromoly version on a clearance sale) and its fine. No changes necessary. You may not be so lucky as saddles are notorious for not being quite right without some trial and error.


Again… this is about comfort. But budget is a factor as well. I tried going with a more or less period-correct option via some old cage pedals with mtb clips and straps. I had them on a shelf collecting dust, and thought this was a great place to put them back into use.

Wrong answer. Some things are better left to the past. Toe clips are one of them. I only had to fumble getting back into them once (I’m not cleating in here) to remember how annoying that was. Fortunately for my budget I also had a pair of perfectly good, cheap flat pedals on the shelf, which I put on.

And I still wasn’t happy. Again thankfully for my budget, my Smash is stored with its pedals off, and those pedals are Pedaling Innovations Catalysts, which are sort of monsters, but I have several sets. I really like the ability to support my arch, in a mid-foot position that benefits from a stomping pedal stroke.

New bike. Scruffy pedals swiped from another bike. No problem.

So on they went and … perfect. I’ll use the cheapie flat pedals on the Smash. For now.


Finally, I built a bike I did not need to play musical chainrings with to get it geared right. Some of that was luck, some of it experience. The 40T Lekkie I used – which requires a special motor cover to be substituted on to fit – was a big ticket item, but its the smallest chainring available that would give me the offset I needed to get excellent chainline on this build.

Pay no attention to those wires. Cable management was tackled on Assembly Day 3. This picture was taken on Day 2.

That chainline was figured out in the Tinkering phase, when I had only the frame, the motor, a wheel and some of my spare chainrings to play with. Chainline is dead straight back to the middle of the cluster, and the gears I am comfortable riding in on this bike are the middle ones as well. One and done. For once.

So… maybe Planning Really is Everything.


The Apostate pictured in my Day 1 ride didn’t stay the same. Most of the changes are documented above. But things don’t always fit into neat little categories. What unique bits did I end up changing or prettying-up?

Battery Mounting

The battery solution on this bike came out great. The frame fits a certain type of ‘in-triangle’ battery pack, and of those packs, the Wolf Pack from Luna Cycle fits as if the frame was made for it.

However, clearances are tight. Particularly on top where it really matters. It was clear even during test fittings I wanted to keep this battery permanently on the frame and remove it as infrequently as possible. Ideally: Never remove it.

Not just because there isn’t much room to work with in terms of getting the thing off of its (super strong) magnetic mount. That strong magnet, versus the rivnut bottle bosses on this vintage frame… worry me. You have to apply so much force to remove the pack (or move it in any way forwards or backwards), I’m concerned something is going to bend (the mount) or break (one of the bosses tearing loose from the frame). There’s likely no coming back from a failure like that on an aluminum frame 23 years old and counting.

Why use the cinch straps if the magnet is so strong?  
The straps provide additional stability and support.  I want to do everything I can to take as much stress off of those two little rivnutted M5 bosses in the frame, which otherwise are holding the entire 9-lb battery on their own through all manner of road and trail shocks.

Initially, I used three velcro cinch straps to nearly cover the pack, and also stabilize the magnetic mount as much as possible. Later on, I decided to take advantage of two of the three slots on the battery side’s mounting tabs. These exist so hose clamps can literally clamp the battery permanently to the frame.

The clamps further reduce the reliance on the bottle bosses to do all the work of holding onto the pack. I had already padded the underside of the mount with a thin pillow of red silicone tape. The hose clamp makes no contact with the actual frame thanks to the mount width on one side, and the wire tunnel for the shift sensor and main motor harness cables on the other.

Those clamps also help reduce the potential of battery theft. Sure, nothing is going to stop a determined thief, but the hose clamps – and I made a point of not hiding them for this reason – make it clear to anyone looking that a few minutes (or an angle grinder) will be needed to get that pack off the bike. There isn’t going to be a grab-and-go theft. That fits in with the very limited likelihood of leaving this bike outside at a shop, locked but unattended.

If someone tries to steal it anyway, once a thief shears off or unscrews the hose clamps, they’ll be confronted with that magnet. I bet it will take some time to realize whats holding the battery so tightly. And once that realization dawns, they will have to figure out how to get it moved just right to angle it out of the frame.

Thats time I can spend setting bear traps, digging pits and buying a baseball bat.

I also used velcro to ‘face’ the cinch straps. This holds them together – really only for cosmetic purposes. The straps don’t move once tightened down. The facing (on the sides and the top) just makes the velcro present a little better; keeping the graphics on the battery from bleeding thru in the gaps between the straps.

Handlebar Bag

The Condor Deployment Bag is something I use on almost all of my bike builds. Its easy to adapt into a secure handlebar mount, its small but still the perfect size for a tool bag that can also hold a wallet, phone and keys. These bags are my go-to for hiding wires – and especially controllers – on my 2wd bikes.

The original brown bag was replaced by a black one I also owned – when I finally found it.

Having several of these on hand, I simply switched from a brown one to a black one. The reason is straightforward: black wires blend in better when they are running along a black bag. Note that in some of the photos you may see a lot of wire stuffed behind that bag. I didn’t cut down the brake hoses to size until the very end of the build and test ride process.


This was a big change, but not for an overtly obvious reason.

The vintage Kalloy Uno seatpost that came with the frame worked great. Except as noted above I had reach issues. I had already moved the seat forward, and I did not want to shorten the stem as that would create other issues. So that limited next steps in terms of fitment.

I didn’t need much reach reduction, so I decided to do a seatpost with no setback. My first thought was a Thomson Elite. Which is a great product but not a trivial purchase at about $115. Since I was in that league in terms of cost, I decided to try a dropper post. They all have no setback. A dropper would be handy for all the reasons droppers are handy.

Also, the frame introduces constraints. The post can’t be super long. 350mm is the right length for a seatpost when fit on the frame to my anatomy; any longer means it protrudes down towards the shock, where the potential for contact is worrisome. Droppers tend to be in the neighborhood of 450mm long, so I wanted to find one with minimal drop. Those posts tend to be closer to 400mm. Also I didn’t want to blow the already blown budget, and a really good dropper costs big money.

I found an interesting option that would be an experiment of sorts, and decided to try it: I bought a PNW Components Coast dropper post, with external cable routing. I could have done internal cabling but a cable coming out the bottom hole in the seat tube could once again be a contact risk with the shock.

Why is the Coast an experiment? Because it is a – unique on the market – suspension post as well as a dropper. Advertised motion is 40mm (it can be more) and its a weird choice because this bike has full suspension already. My reasoning behind doing this – and my results – are enough for a full blog post all by themselves so I’ll just say I did it and it worked well.

Dropper post, with wiring thats not too bad; piggybacking onto the brake hose. Ignore that cheapo temporary seat collar.

As a dropper. Jury is still out on whether it is also an effective suspension feature, but it does seem to work for me in an unusual sort of way. Stay tuned for a separate post on this oddball idea and result.

After all was said and done, I did find a way to test whether there was risk of the seatpost hitting the shock: I removed all but about 20 psi of pressure, which let me easily compress the frame by hand, and observe the result. It turns out, for my frame, there is no risk of contact. Perform this check with yours to learn your result.

Seatpost Collar

This one was pretty straightforward, but boy was it frustrating. I have had occasion to lock the bike up outside a store. The Salsa quick release seatpost clamp that came with the frame carried the usual risk: It makes it easy to steal the saddle and post. Since I am using a US$170 dropper and a US$95 saddle. thats worth taking steps to protect.

With a dropper, there is no longer any need for a QR clamp. So time for a fixed collar. I chose a Bike Yoke Squeezy in 35.6mm size, which turns out to be the wrong size thanks to a mistake on my part. Hint: Take the seatpost clamp off and measure under it. Not below it. This frame has two external seatpost diameters, which is invisible if you leave the clamp in place.

Why the Squeezy for a post clamp? It was a whim. The Squeezy is a bit of a unique animal and I wanted to try it out. Its a neat idea and well-made.

But there was that sizing issue, which I was only able to temporarily overcome with some shimming. I ended up finding a basic 34.9mm Axiom seatpost collar in my parts pile that I made work. Its an unremarkable part not really suited to this build. Still, it was handy to just install so I could move on to the next job … and wait for my annoyance at myself to subside so I could spend another US$35 for the correct 35.0mm clamp. Its on. It works. It holds my weight over time with no shifting. It looks great.

The Squeezy defines low profile. Note the very light torque specification. The T25 socket adds a hair of security without requiring an additional tool in my onboard toolbag.

The Wire Harness Tube

This was a unique need for this build. The usual preferred solution of a battery bag in the triangle didn’t work on this frame. Not so great news, as you use the battery bag to hide wires. My best solution to hiding otherwise bare wires was to enclose them in a pipe that more or less matches the frame.

I originally used cheap red PEX pipe purchased locally for about the price of a candy bar. I ended up not being happy with the red color and did a spiral wrap of red silicone tape to get a better match. In a short time it darkened to be a near perfect match to the frame. But it also had a few problems:

Rips like this only get worse with silicone tape, which becomes easier to tear as it ages

The tape was just not durable. I had rips and breaks in it – more than in the picture above . Also, I had cut the pipe a bit too long. When turning the bars to an extreme, the fork poked the top of the tube and pushed it to one side or the other.

Oops. You can see how the fork pushes into the tube when its turned to one side.

The solution was to replace the pipe. I used a length of furniture grade, red 1/2″ PVC – a better red than the PEX came in, so no tape. I had to wait a couple of weeks for it to arrive. Cost was about US$20.
