I rode a bicycle with an engine kit for about 5 years, running errands and commuting to work at times. It worked well for me because the state law allowed me to ride in the bicycle lanes, which were plentiful.
-Without those bicycle lanes being available, I would have bought a scooter instead, for safety reasons.
-Mounting an engine kit on a bicycle is a great way to teach or learn basic engine mechanics, beca use the kit engines are so simple.
-For most people in most situations, I don't believe a motorized bicycle will be as safe and reliable as a 50cc motor scooter.
