I'm building a little electric bike for a project. Its a small kids scrambler type bike that Ive removed the engine from, slightly bigger than a PW50 Yamaha. I need help choosing a motor to suit, probably 24V but I don't know what size Watts? I don't want it to be underpowered or overly fast for that matter! Would a mobility scooter type setup be useful as I could get my hands on that or am I better off buying everything individually? Any help appreciated.

Hi, What is the power output of the petrol engine? Use an online power conversion calculator to tell you the size in watts. Then you know what size motor it needs. Bearing in mind the different speeds of the two motors you can then play around with gearing to give you the best balance of speed and acceleration. How does the weight of the bike compare to that of a mobility scooter? Then all you need to do is find how to get enough batteries in the frame. Simples!!  Colin |

I have anelectric adult scooter, 800w 36v. To be honest it's in the garage doing nothing and has been for a year or so so the batteries are proberbly dead but it will have all the controls, Cables chains and stuff you may need.
800w was fine for my commute and ran at 20mph for about 2 hours on a full charge.
If it's any use pm me an offer of you like
