Re: the perfect motorized bike?
Welcome to the forum deft. I am with you in spirit 55 mph on a bicycle is real fast. Some of the better bikes use sealed bearings I am not sure how they would hold up at those speeds. Remember the designers never intended for these bikes to go that fast! Brakes are another issue. You have a good game plan just remember these are bicycles.
