Re: Will an 80cc motor handle my weight?
I weigh 200 and a 50cc china motor pulls me fine.
I agree that you should invest in a strong back wheel (from a tandem bike or industrial bike, or have a shop build one for you). It will help your tires and brakes last longer and save a lot of hassle down the road.
