How To Build a Mid Drive Ebike That Doesn’t Break

This will be a companion post to How To Ride a Mid Drive Ebike Without Breaking It. If ever there was a tale that needed telling over and over again, its this one. I have to consolidate the various discussions on this site into a single go-to I can link to (over and over again) as this discussion comes up rather a lot.

STATUS: Writing has begun. Its going to be quick since it is at least partially a compilation from earlier work I have already published, and I seem to wish I had it available daily.

Tool Kit: The 2022 Edition

I’ve made some changes to my tool kits since I originally wrote up my full kit and basic kit in late 2020 and early 2021. The differences are worth mentioning.

STATUS: This one is complete, but given the need for the mid drive building article its going to wait for publication afterwards. Probably August 2022.

Microshift Advent: Budget 1x Ebike Drivetrain

With the Mongoose Envoy’s recent move to the Monterey Bay Area from its former home in Fresno California, I found myself using every cog of the 11-32T Shimano HG400-9 cluster that I have installed. Running on the inner cogs like that means bad chain alignment. I need to be running further outboard and that means I need a different, much wider cluster.

But that 1-piece steel, pinned Shimano cluster is pretty much indestructible when paired with a powerful BBSHD mid drive. I’ll be losing that indestructability. Or will I?

Left to right: 11-46T cluster, Pro shifters and long cage, clutched derailleur

Microshift provides a potential solution. They are selling their 9s Advent component group to singletrack riders on a budget – All three pieces ran me around $125 total.

The Advent group was introduced in 2019, but very recently got an evolutionary upgrade.

Can these parts also fit a street-driven, electrified cargo bike use case? Can they take the kind of pounding a 30a BBSHD mounted to a cargo bike that could be pushing 450 pounds or more total system weight? From where I am sitting, the Advent group borders on being revolutionary to DIY ebikers. We’ll look at them in detail, pre-, during and post-install.

STATUS: Up next for production. This group has turned into a real winner so expect it to be done as soon as there is room in the publishing schedule.

2Fat Gets A Major Facelift

The point of this exercise is so 2Fat can better handle long runs on deserted stretches of super deep, dry and coarse beach sand. This is the first alteration since the bike rolled off the laboratory table in 2017.

  • Surly Moonlander front fork (installed but bad… needs a do-over)
  • New (re-used from parts pile :D) front rack to take advantage of the Moonlander’s barnacles (installed)
  • Box Components Prime 9 Drivetrain (installed)
    • Box 2 Extra Wide 50T-capable derailleur
    • Box 2 single-per-throw E-shifter
    • Box 2 144 link chain
    • Box 3 11-46T all-steel cluster
  • Just-in-case Sunrace CS-M983 11-46T steel cluster (in hand… Spoiler Alert: its identical to the Box 3 cluster)
  • Battery capacity increase from 25ah to 32ah (same size and weight) – (installed)
  • Kinekt suspension stem with dampener enhancement kit (installed)
  • Replace worn 26×4.80″ Snowshoe XL tires with 26×4.80″ Snow Avalanche’s (Rear installed; front needs a Plan B)
  • Handlebar extensions using a similar method to what I did with the Surly Big Fat Dummy’s bars. (installed)
  • handlebar extension inserts for XXXXL grips (installed)
There’s something funny-looking about those Jones handlebars…

STATUS: On hold. This bike’s future is uncertain given what appears to be a dead motor (or at least a dead connection) along with my not liking hating the new fork geometry. I am on the lookout for a new front fat motor to resurrect the bike. Prior to the motor failure, after some serious remote excursions, everything seemed to be working well.
