F.A.Qs 

A bicycle engine is essentially a gas powered bike that uses a 2-stroke motor.
The engine is mounted at the center of the bicycles frame. It uses its own drive chain that is connected to a sprocket that is installed on the rear hub of your wheel.

Our bicycle engine kits use a common type of engine known as 2-stroke technology. They are very basic in design and contain a lot less moving parts compared to its counter-part 4-stroke engine. Two stroke engines are the main choice for many applications where performance and reliability in a small package is vital. Outboard engines and snowmobiles were exclusively 2-stroke for many decades. This is why we continue to use 2 stroke motors for our bicycle engine kits. 

If you are looking for a replacement chain for your bicycle engine kit, body cylinder, or even electric parts such as a magneto then we have you covered. Just visit our replacement parts category to view our full list of replacement parts.
