Ebike Wattage Recommendation
IhaveaWelderandaDream:
I'm working on converting a 90cc motorcycle to electric. I have been looking at a 5kw and a 10kw motor to run it with, but that seems pretty low compared to some of the commercial bikes I've seen.
I live in a pretty rural area so it's pretty much a requirement for it to hit 60-65 just to keep from getting tailgated. Are the listed wattage capable of hitting that mark? If not, what kind of wattage should I be aiming for? Any advice is appreciated.
princec:
11kW should manage 70mph, just about, but that'll be flat out of course.
Cas :)
IhaveaWelderandaDream:
Do you have any motor recommendations around that wattage?
princec:
Me, no unfortunately but there's a few knowledgeable types around here who will be able to come up with something.
One thought: get a motor out of a crashed Zero FX. Insane of course but nobody said you had to be rational :P
Cas :)

If it's a 90cc I'm going to assume you won't have much frame space to play with for the motor and battery. You could get 11kW out of a hub motor. The Stealth Bomber comes as a 12kW version and the 8kW model will apparently do 70mph.
