We used this to upgrade a Hyper 350 electric dirt bike that came with a 24v 250w motor so the 36v 500w motor was a HUGE upgrade in torque. Originally the bike was sluggish with my 200lb self on it, now the bike will do a wheelie if you give it full throttle on takeoff. The motor rpm was a good matchup. To complete the project, we had to buy a new motor sprocket, longer chain, an extra 12v battery, a female charging port, and cut up the chassis to fit the bigger motor.
