49CC Rear Mount Engine on a Mongoose Ledge. Added fenders, mirrors, cell phone holder, exhaust system. Replaced tires with road tires. I almost never rode it off the paved surfaces prior to motor installation. Not a kit for the novice as some mechanic and engineering skills are very helpful. Rated at a top speed between 20-30 Mph and fuel usage between 100 and 150 Mpg. My top speed so far is 31.8 Mph and still using my first gallon of fuel.
