I have an old GT avalanche . Looking to do e bike conversion , I want something that will do 30-40 mph, but something I can rip on a bit . I’m à trials rider at heart so I wanna be able to jump it and do some thrashing… is 1500w enough? Should I get a hub motor or try to fabricate a crank style or frame mounted motor? Mainly something I can twist and go but still obv retaining pedal ability. Also not opposed to going single speed but then the question is can I get the torque I need to accel quickly …
