Ebike Misc Parts Source?
 

So today at the shop a inexpensive ebike. Comes in with a broken brake levers. This is the kinda with the electrical lead that causes the motor to pause. I told the customer sorry.
We probably should take care of these issues but the owner isn't interested I the "crappy" bikes.
And our main source QBP doesn't have these kinda of parts.
So looking for a dependable source.
Suggestions would be great!

A search will usually turn up sources for various cheapy parts for all kinds of equipment not using quality parts and not sold in bike shops. Lots of hits from AliExpress (which I refuse to give my money to) and Ebay, etc. ebike brake levers with motor pause - Search You might even find the exact replacement as many cheap, no-name Ebikes use parts from the same mfrs. in China.

Good quality e-bike levers:

Before sourcing replacement levers, confirm whether you need the type that completes the circuit or opens it to pause power. I have seen both types depending on the controller type.

I've seen 2-wire and 3-wire versions, I wouldn't be surprised if some use Hall sensors instead of microswitches, although they could just be connected so that normally open and normally closed are both available. Also they come with various connectors including "waterproof" 8mm Julet and various repinnable mini Molex types as well as just tinned ends. So if you're going to carry some stock there are potentially a few possible configurations. I'm surprised that AliExpress doesn't sell just the switch and cable for these, but I've not seen them.
