I am building an "alternative fuel" motorcycle.(adsbygoogle = window.adsbygoogle || []).push({});

But i am having trouble figuring out what size motor i need to use and how much torque it needs to put out.

I have already figured out my top speed, (I am limiting the prototype) and also the RPMs of the drive tire at that speed. I also have the estimated weight of the completed bike with rider.

I am looking for a formula to determine how much torque is needed.

Thanks for the help.
