Keep it simple stupid.
There is a lot to be said to keeping these e-bikes as simple and accessible as possible. The more complexity that we ask of these bikes,the more failure is likely and the more difficult it is to sort out the problem.
I must say I am impressed by the few failures we have experienced with the Bafang BPM hub drive,a couple with gear failures and so easy to repair. With only 250 watts asked of this motor it is not stressed.
The great advantage of hub drive is the rest of the bike transmission system has the reliability history of many years of derailleur gearing,the gearing is normal bike with only rider power input.
Bosch had a big argument with Shimano over failures in the Nexus hub gearing,that gearing was never meant to accept Bosch power plus rider power and couldn't take that power.
Ok some argue that the hub drive places greater torque directly onto the bikes spokes...we have experienced some failures of spokes,the source of those failures is difficult to determine but the solution is simple and not expensive.
Most of the failures of these bikes is over complicated wiring,Kudos and Woosh are both trying to get these bikes to single cable looms with multi plugs at the display and controller.
Lot to be said for keeping it simple.
