Parts to finish the cargo bike’s tube replacement arrived today, and I was very quickly able to finish the job.
The reason this was so involved is I needed to replace the rear wheel’s tube. Which is the same wheel that has a hub motor (a GMAC-10T from Grin). Which already turns this from a 5 minute job to an hour+ job. However, this time, one of the nylock bolts the motor uses to secure itself to the dropouts (in addition to a torque arm) was slipping (somehow? The threads on the axle weren’t stripped) and I couldn’t get it to the specified torque. Couldn’t find a replacement m10x1.0 nylock bolt locally, so I had to order some (from McMaster, which is expensive, but I know they have what I’m looking for + they’re not Amazon).
The bolts came today, and a couple minutes later, I had a new bolt threaded on and torqued to the correct amount. Quick ride verified that it’s correctly mounted.
This is by far the worst part of rear hub motors. They’re just an absolute pain to get on or off the bike. They offer a much better riding experience than front hubs, but replacing a tube or tire is a nightmare. I should figure out if I can go tubeless with this thing.
Edit: to be clear, this is my only complaint about this setup, and I otherwise love it. I get regenerative braking in a very powerful geared hub motor. It’s perfect for carrying and pulling cargo.
