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 requirements, we must accurately disclose and label the correct engine size to the customer. The true displacement of the A85 bicycle engine kit is actually 85cc. 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. 52mm bore x 40mm stroke is a 85cc engine. (Be aware of companies selling engines with an incorrect CC rating. Usually, these are low-quality knockoffs).

The engine retains the stock 25-degree timing.  

Look for the YD logo on the crankcase to ensure authenticity.   There are plenty of fake A85 engines out there.

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.
