I have recently bought a second hand electrified Gazelle cabby. I think it was electrified 10 years ago.
I am really underwhelmed with the front wheel (20") hub motor. It is a 36V 250W no-brand motor. The controller is a KT 14A controller. I have allready tried it with another battery but the results are the same. If I have to go up a bridge or even a mild slope the motor is no longer able to provide enough power to get to 25 km/h... I really have to hit the pedals hard to even get 20km/h
I also have a (rather heavy) bike with a Bafang BBS01 mid drive that i put together myself and that goes so much better, so I have something to compare it to...
Could it be that the old controller has it's best days behind it and would a new (maybe 17A) controller make things better? Or would I just be throwing my money away? I could not find anything with goole on maybe the old mosfets getting less powerfull with age?
