Don’t let the name fool you: these parts are from Flying Horse, but they fit a wide range of 4-stroke engines, including the Grubee 4-stroke engine and nearly all Huasheng 142F 4-stroke bicycle engine kits. As long as you have a 4x bolt pattern for your transmission and a 3” bell rotor configuration, you’re ready to ride.

Killswitch broken? This kit’s got an entire standard throttle grip (grip color varies) and kill switch assembly with a throttle cable. Is your bike not riding the way it used to? This kit comes with everything you need to rebuild your drivetrain, from a brand new transmission and 44 tooth sprocket, to a sprocket clamp assembly, idler, and chain. And if you’re tired of that little black, plastic exhaust pipe whining when your ride, this kit includes a brand new 4-stroke muffler.

On top of all that, there’s also a wide crank set included so you can finally start pedaling your 4-stroke motorized bike instead of keeping your pedals stuck behind your engine. Don’t forget about the basics: you’ll need the included mounting bracket to mount the engine to the bike, and a new gas tank to swap out with that old dinged up one.

Whether you’re trying to rebuild your 4-stroke motorized bike, or you have a 4-stroke lying around you want to get back on the road, with the Flying Horse Complete 5G 4-Stroke Bicycle Engine Transmission Kit you’re back in business.
