Engine Parts

This kit includes everything in the picture above:

A motorized bicycle can run up to 35 mph for a 200 lbs rider, and faster for smaller riders. This engine consume about 120-150 Miles/Gallon of gasoline. A well maintain engine has average life span of 1-2 years under normal use.    

This complete small gas engine kit is suitable for bicycle with V-shape frame. Some people also use it for go cart, small boat, lawn mower, etc. Although, some "DIY backyard mechanics" can setup the engine kit on a bicycle, but we recommend that this engine kit to be install by a motorcycle/auto mechanic. Cruiser type bikes with a seat tube inside frame length of 12 ? inches and 70 degree included frame angle work well. The engine is normally supplied to fit up to 32mm seat tubes and 35mm down tubes. Shimming maybe required if installing on smaller diameter frames. It is best to take you engine to the bike shop and compare fitting before buying a new bike.
