Friction drive killed my tire

[josephusflav]

So i just bought a friction drive bike

It worked fine, but we had to partially disassemble it to ship it home

Once it was home i rigged it all up.

I guess the off switch for my motor wasnt hooked up properly because once i started the engine i couldnt stop it

I the drive shredded my rear tire till a puncture formed.


I was able to solve the runaway motor problem but I'd like some tips on to know exactly what level of contact is needed between the wheel and the drive

Do you plan on peddling much . if not and that is the only reason to put a motor on a bicycle. The best way to achieve friction is to lower the tire pressure to 32psi in dry conditions and 18psi in wet conditions . I use a 79cc predator Friction drive bicycle . Rode it across America this year Florida to California and back. Used the same back tire all 4500 miles and probably still go another 3000 miles .
What kit are you using?
