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 Don't be fooled by other retailers, selling outdated, non-EPA approved, old generation bicycle engine kits!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. Older production of these assemblies included 2x sets, but from testing and redesigning, existing engine kits and engine kits in the future will only require 1x set. This redesigned assembly helps secure your rear wheel sprocket better than in previous production. NOTE: Wide Crank Assembly are only Compatible with 9/6th inch pedals. Will not be compatible with Micargi Beach Cruiser's stock pedals.

Bottom bracket is not included. If the bike being converted has a one piece crank assembly, you will need a bottom bracket found here Bottom Bracket

Looks great

Haven't got to ride it yet

Robert Reid
Awesome engine

I love this little engine, it is so quite and efficient. I find every reason to go riding now because it is so much fun. I definitely recommend the 49cc engine kit.

Peter Brown
Looking forward to good times

I really like this engine. It’s not too loud, good low end torque.

I bought two engine kits, good thing, I wound up using parts from the second kit to finish my first bike.

I’m going to have to buy more parts to finish my second bike.

Donald Myers
Excellent Choice

I have built 5 bike kits before this one, a 212cc, two 4 stroke 79cc, and two 66/80 two strokes... this 49CC kit was a BIG SURPRISE how easy and how much power it has, I weigh 215lbs and it zips along around 22 mph (40 tooth sprocket). I now have 85 miles on it with zero problems. Lots of fun!

Mark Gillis
Great multi fit kit.

Haven't finished my build yet , but all parts seem fine. I've made a few changes because this kit isn't made precisely for stretch beach cruisers.
