Upgraded. Better Quality. Better Performance. Guaranteed.


This brand new 80cc motor assisted kit is cool, quiet, easy to ride and pure fun!


The kit comes with everything you need to make your very own motorized bike that can propel you up to speeds of 35 mph and shoot strait up even those toughest hills at 25mph. You can still pedal when ever you may like. Even though it does not fit all bikes, it works great on bikes like cruisers and old mountain bikes!


Why our 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 than any other bicycle engine on the market. This engine has way better hardware and has super 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.
