Why our engines?

Don’t be fooled by low quality competitors selling bottom dollar engines!

We have tried several different types of this engine, made by different factories, and we found after many months of testing that this is the best motorized bicycle kit. It has the best quality, more than any other bicycle engine on the market. This engine has much better hardware and has high quality Japanese bearings that make this engine kit faster and stronger. No crappy bushings! Don't be fooled by poorly performing engines, and buy one you can trust.

Other sellers cut costs by using poor quality bearings, bushings, and hardware. They do not have a brand name to back their products. They are simply making the engine as cheap as possible to trick unsuspecting buyers who may not be familiar with the importance of having good quality hardware and bearings. These engines do not last and are being produced and sold as quickly as possible.

Please note- we do continuing improvements every year. May slightly vary from photo.

Assembly required. Engine requires top end installation, easy job with pre-installed piston.
