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.

The crank shaft is pictured but not included. The company will not make good.

Terry Alfrey

Clutch bell shaft was too long and interfered with installation , once that was resolved it works fine . I would like to be able to get a larger output sprocket .

David Foy

I like the bike motor .It works great , My bicycle is a Schwinn Adult Tricycle .

5 star if not for the minor customizations.

5 star if not for the minor customization to chain tensioner and I added some some extra bolts to the engine mount. Had a slight twist when throttling which caused the chain to jump from the sprocket. So I added a couple brackets. 1 engine mount bolt broke during install but with my add ONS it's solid as a friggin rock!
Throttle grip could be upgraded. Kinda cheep. Overall I'm totally happy with my purchase.

-ill add some pictures of my "add ons" that keep this pony in place tomorrow.
(Que suspenseful music).....
