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. There is no such thing as an 80cc bicycle engine kit (This is only used as a marketing gimmick).
All of our bicycle motor kits are now equipped with a catalytic converter exhaust with a Palladium filter insert. This greatly reduces the number of pollutants coming out of the engine. No other motorized bicycle engine kit has this in Canada.
