Welcome Hamop to the forum, glad you joined

2-stroke...the 70cc has got little more torque then the 48cc I think if you used a 50t sprocket you will be okay

4-stroke dont know to much about them...
here is a link to measure for the belt drive
What kind of bike would you recommend?

I forgot to mention..for the 4-stroke check out Thats Dax titan chain drive...I've heard nothing but good thing's about it

bicycle engine kit, bike engine, bicycle engine, bicycle motor

Thanks looked at it,question how does the sprocket mount on the wheel? can't see how it does looking at the pics!

It mounts the same way as a two stroke does. Although Cruiser has got a cool set-up where the sproket mount's to the hub

If you have rear disc brake, King's sales and service (see ad on top left of page) can do sprockets to mount to the disc hub. You'd have to find a new rear brake though.
