These mopeds typically go between 25 & 40 mph. These will all have the original 49cc cylinders, but often feature upgraded and/or de-restricted carburetors & exhausts. All stock and stock-like bikes have been fully gone over and had basic components replaced as needed; so most come with new cables, chains, spark plugs, grips, bulbs, tires, etc. Some even have full aesthetic overhauls. Check out the individual bikes for specific info.
