This motorized bicycle engine kit comes with everything you need to turn almost any bicycle into a moped. You can start and stop your engine as you ride. You start the engine by pedaling so no rope or pulling is needed to start the engine.

With the angle fire slant head motor the spark plug is at a 45 degree angle instead of pointing straight up. This gives the engine some more compression and can add up to an extra 5 km/h to your engine.

As per legal requirement we need to accurately disclose and label the correct engine size to the customer. The long standing factory branding of the 80cc bicycle engine isn’t accurate. The true displacement of the GT5 bicycle engine kit is actually 66cc. Volume is calculated by V= pi x Radius^2 x Stroke. In Canada the volume of the cylinder is only used when calculating the engine displacement. 47mm bore x 38mm stroke is a 66cc engine. This is the largest motorized engine that exists..

All of our bicycle motor kits are now equipped with a catalytic converter exhaust with a Palladium filter insert. This greatly reduces the amount of pollutants coming out of the engine and makes our engines. No other motorized bicycle engine kit has this in Canada.
