[QUOTE=PromptCritical;23367289]Did the front wheel drive cause any other handling problems? We only want the motor to put out a maximum of 150w and wouldn’t be using a hand throttle so wheel spin shouldn’t be a problem.[​ ​ ​ ​
No, that system functions perfectly even after 10 years. The Shenghi motor, in concert with its controller seems designed well for a front application. The only reason I don't recommend Dilleneger these days is they seem to have pretty much abandoned the US market and their batteries may have been sitting around a while, although the one on that bike is seven or eight years old.
