So, what if we came up with a small lightweight friction drive unit just for emergency power? What do you guys think?
makes a friction drive that you can carry in your back pack and can install in a jiffy.
25 cc at 3.5 HP so they scream too. I rode one at the races and it was a blast
at 14,000 rpm.....
they cost about $800 and are mainly sold to down hill mountain bike guys that spend a lot more than that on their bikes.
so how about just making your ride reliable?
