Moped Army

It seemed great for the price, but I never thought about the weights effect on the brakes. Saw a cheap chinese 110cc bike with a Lifan that looked like moped. Might just buy one of those off ebay for cheap and transfer the spoke rims equipped with better brakes, wire harness, and engine over. Only a little pricier than an 80cc set-up with Motomatic pipe is gonna run. Why not have gears? After all this project is for a mud/beach blaster.
