Im running a bumblebeebolton. The designer is a buddy of mine and he wanted to make motorized biking as simple as possible. he has it set up to where the drive wheel is either on the tire or off the tire..the whole kit is held on by one bolt! Really! Check it out! I haven't been riding mine lately been to busy but i used to ride that thing all over town everyday!
I would like to see them use a more powerful engine like the ht or robin..there running a 26cc but they get around 27-30mph thats over a mph per cc!
