Sorry to resurrect this Zombie thread - duckduckgo brought me here.

Same issue with my u616. I can hear something inside make a low humming noise - like a motor turning but not sure - but the resistance never changes. Gonna crack the case later tonight and have a look. If it looks like the brake motor I'll order, either way I'll post back in this thread hopefully it helps someone else.

Wanted to post an update here. To get the plastic cover off the bike for maintenance you need a bike crank arm puller - I ordered this one and the threads matched. had to torque the wrench pretty hard to get the arm to release - used a rubber hammer as a last resort and it finally came off. Works just like any arm puller for any mountain/road bike.

Ordered the replacement motor a suggested above. Not really sure what I'm looking at inside this thing but I hear noise and dont see anything moving so I assume this brake motor will help - even if it doesn't it was only 20 bucks. Worth a shot to fix this thing. Thanks for the advice /u/simplefitnessrepair
