Did this video help you?

qpae123: My ''motor '' can do a lot more then 350W and has an authonomy of over 200 km/ day. Tops around 70/80 kmh. ┬áRuns on honey limonade :))´╗┐

Lucasimo: you can't buy the motor separately unless you are an authorised Bosch e bike dealer and even they cannot buy one unless they return a damaged one to Bosch.

fourbarposer: Another possible solution to the noise. Use this sort of freewheel (see the video): "Renold Trapped Roller Clutch" in the engine.

fourbarposer: Mine was about similar noise for the freewheel (turn the pedal backwards while stationary, no engine power involved), but after a year the freewheel now clicks very loudly. I read these should be lubricated/greased yearly, does that require disassembly of the engine? I don't understand why they don't glue cloth padding inside the freewheel - greases are just a temporary solution to noise.

carlosjhr64: Why not get rid of the chain completely and have the pedals power the generator? (Or even just have the chain attached to the generator? This is not what you're doing here but just saying.) A big problem with recumbents is finding a way to loop the chain from the pedals to one of the wheels. I realize there's a power loss, but presumably you have a battery and the pedaling is to increase your range. And what's the efficiency anyways? 90%? Without the battery, would it be like ridding on sand?

TheEdge008: Great post. Would like to hear noise tests of other e-bike mid-drive motors. Thanks again, MrEbiketest.

Rideoak: Great! Thank you very much for the BEST Tip about the right Button. Thats the thing i was missing!!!
