I am still in the market for a motor. This summer, I will be making a 5 mile commute with an elevation gain of about 690 feet (from 6642' to 7332'). During that five miles I will be going up and down during which I will climb a total of 1190'. I weigh about 115#. Will a 4-stroke, 49cc engine make it a pleasant ride or will it just be extra weight? Does anyone have any insight? I plan on mounting it in-frame on an aluminum mountain bike.
Thanks in advance,
