Re: lifespan of engines
YAY!!! Took maiden voyage last night! Vibration transfer up to handlebar and seatpost may get tiring. 80cc 44t too slow on the flats, barely goes uphill unless pedaling.
The bike I'm using is my baby. Personally handbuilt high-end mountain bike with very stout components wheels, and suspension. I used to night ride a lot, so already had dual 12w lamps, one spot, one flood. Will get another flashing red taillight, as well as those reflectorized velcro bands for my pantlegs, to keep them from hanging up, as well as provide a visual wobbling notice for cars from the side as well as rear.
