70mph on a bike, lol i don't think most bikes are built to handle that much vibration and torque. Your tires might wear out really fast and make the tube blow out.

I built a 66cc two stroke build once on a cheap mountain bike and put on a SBP expansion chamber and all the low end torque stuff on it. I think i spent more time fixing the bike than riding it because too much power loosened up almost every bolt.

I later built a 49cc with a smaller sprocket. I had to pedal it up to about 6 mph before i pull on the throttle but it was quieter because smaller sprocket gave me lower RPM.
