I have a 70's Sears Free Spirit. i've been contemplating putting a 65cc motor on it and putting around. my only worry is that the wheels and brakes won't be able to handle the speed. (35-40 mph tops) Has anyone done this before, and does anyone have any recomendations? I plan on ordering the motor from www.thatsdax.com . a guy a my work ( a bike shop no less) has this engine but it's mounted on an older Trek 820 so it's a little more sturdy and has a front suspension.

Any recomendations would be lovely.

Eric.


p.s. this is the free spirit.
