I have looked around quite a bit on this site about drive rollers, some good info.

What size drive roller should I use for my friction drive bike?
I have a 31cc Ryobi weed wacker, 24 inch tyres, I only weigh about 50kg (110lbs) and my area has some hills.

Thanks.

I had a look around my garage and found heavy steel pipe about 1.25''. If thats not good then i have a few smaller pipe and bigger pipes to experiment with.

Thanks
