Ready for a ride that will last? If you’re looking for a tough, reliable, long-lasting bicycle engine kit look no further than our BBR Tuning 5G 4 stroke engine! The all new BBR Tuning 5G 4 stroke bike engine kit features a centrifugal clutch and pull start enhancements, with all of the latest features and upgraded components BBR Tuning has to offer. This 4 stroke bike engine kit is truly the cream of the bike kit crop. Forget premixing oil and fuel! Instead, this engine features an independent oil reservoir which keeps the engine well lubricated. This is the reason the 4 stroke engines are known for their reliability and long life. Moreover, with the centrifugal clutch feature, there is no need to engage and disengage the engine manually. Similar to an engine for a scooter or goped, you simply pull the starter chord and hit the throttle to go! When the bike is stopped, the engine will automatically disengage so that the engine will stay running. This kit is perfect for those that are looking for the added reliability and ease of use of a 4 stroke engine with an automatic transmission.
This kit comes with all the components you'll need to convert a compatible bicycle into a motorized bicycle. Startup is a breeze and you can stop the engine with a simple killswitch provided with the throttle assembly. Don't be fooled by other retailers, selling outdated, non-EPA approved, old generation bicycle engine kits! All of the Flying Horse engines feature the latest updates, including high quality needle bearings and Japanese ball bearings. Older generation engines use cheap bushings that do not last! BikeBerry.com takes extra measures to ensure our manufactures abide by strict quality control assurance measures and use the highest quality material so that we can make certain that all of our customers get only the best!
** Please note: Sprocket Clamp Assemblies included with BBR Tuning 2-Stroke 48cc and 66/80cc, and 4-Stroke 49cc bike engine kits come with only 1x set of metal plates.

Good quality,fit my bicycle perfectly
Everything in the kit worked out good for me except the gas tank, the tank came with lots of rust in it, I tried calling customer service big mistake, they could care less about your problem, I ordered different tank on Amazon and bikeberry did eventually replace rusty tank but took 8 email's and 2 weeks, but motor runs great everything else works great got over 100 miles on it now & ride it about every evening, I installed it on a hyper cruiser.
Tank was rusty inside, welds for exhaust were flimsy and there is no way to connect killswitch to engine unless you either slice off some rubber and use electrical tape, or got some wire connectors
Great kit amd easy assembly!!
