This document describes how to convert a bicycle into a gasoline-powered bike, or "power bike". It can reach speeds of 35 mph. The bike uses a 1-hp Briggs & Stratton engine mounted on a steel base plate welded to the bicycle frame. The rear wheel is altered by welding on an extra rim to act as a drive belt pulley. Various small parts must be made, including a clutch and braking system. Instructions are provided on installing the engine, exhaust, fuel and electrical systems, drive belt, controls, and maintenance. Modifications may be needed depending on the specific bicycle and engine used.
