Homebuilt cargo bike. Plenty of miles. Huge hills. Usually with a 40lb dog and some groceries. BBSHD gets me up hills under load faster than I need to go. Have never replaced the chain. Have never needed service on the motor. Chews thru brakes tho! Meanwhile, there are lots of rear hub motor RAD...

This BBSHD longtail has been hauling my fat but up the 400' of vertical at 10% grade between town and my residence with 40lb pup and groceries for several years. Original drivetrain, battery and motor have never needed repair or replace. Recommended.

The BBSHD has a 24 tooth clutch. 360degrees/24teeth=15degrees/click. I believe the Exposure hub that comes with the bike is also 24tooth. The slop stacks up randomly between the two, so best case is immediate engagement and worst case is 30 degrees which is just what I estimated that it did once...

Axle to axle is 51". Even if you spin the fork around it is unlikely to fit on a bus rack. Some of the 20" cargo bikes will.

My list in order of preference is the DT Swiss Hybrid, Spank Hex and Hope Pro 4. SRAM 900 looks ok but can't confirm that the end caps are available. Last option is the Koozer which is cheap enough to buy 2 and swap out if there is a problem, but do I really want to do all that for $100? It all...

Same here. In the midst of a wheel build. Got the front done because that was the taco. Sun MTX33 rims with DT 2mm spokes and a DT Swiss 350 hub. Yes, the rear is a bit tricky. Planning on a DT Swiss 350 boost 148mm rear plus QR caps to take it down to 141mm QR. The Koozer BM440 might also work...

Maxxgabriel, I get the same thing. Sometimes late engagement. Sometimes a vibrating sound. They are difficult to reproduce and only happen when riding, so I've had trouble pinpointing, but here's what I think is happening. On the late engagement, I think it's a clutch in the BBSHD that engages...

Maybe just get the Jones bars? Another idea... When I first got this bike, I thought I would be riding slowly and that an upright position would be best. Even put some risers in the stem. Since then, it has become clear that the upright posture is costing me lots of battery. The included bars...

Shim to fit the gear housing which is the 47x64 measurement. The gear housing has a rounded edge, so may not need the whole 64mm. You can then decide if the chainring fits and the chain line is right. You could go for a smaller ring that is offset to bring the chain line back in. Then look at...

Had the same dilemma. Either the cable gets bent more than I would like or the motor hangs too low and might catch a curb. Decided to drill a hole in the top side of the base of the down tube to route the cable over the top of the BB and on to the chain-stay. This would provide a good cable path...

Usually a few taps of the wrench with a rubber mallet work to remove a decade old BB. Much of the Envoy was assembled without any lube so it's no surprise me that this new BB is sticking. On initial assembly I noticed a dry headset dusted with aluminum shavings so decided to completely...

Have not noticed any frame flex. Even with a passenger or cargo on the back it is quite solid. Have never ridden a bike that felt this stable at speed before. The rims are narrower than I'd like which is visibly unnerving, but no issues there. The one thing it won't do well in terms of stability...

Not at all. Please do.

Very good, timely customer service from BafangUSAdirect and Grin. Extremely poor service and response from a certain moon themed company.

Looks very nice! Would you tell more about your programming? I find that my ideal pedal cadence is substantially slower than the motor's most efficient RPM, but don't know how programming can help since they are both coupled by the same drive train. Does your programming change address this?
