The BBR Tuning Angle Fire 48cc engine kit is the performance enhanced 48cc engine kit. This engine kit is enhanced with a angle head plug which creates a higher compression, which in turn produces more power!

This kit comes with every thing that you'll need to convert bicycle into a motorized bike. You will still be able to pedal the bike and ride like normal or start the engine by releasing the clutch lever. There's no rope pulling needed. You can stop or start the engine as you ride. Don't be fooled by other retailers, selling outdated, old generation engines! All of our engines feature the latest updates, including high quality Japanese ball bearings. Older generation engines use cheap bushings that do not last! We make certain that all of 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.

With these strict quality assurance measures, we are able to offer a industry leading 6 month warranty!

I run 32:1 it does well. I have the large down pipe expansion chamber . It makes a big difference from the stock exhaust.

kinxs the furry
very good engine bad tensioner

i got the engine in a week ago, and it runs great, if you are riding in the cold PLEASE put a shield in front of the engine to keep it warm, the engine doesn't put off too much heat so it cools down too much in the cold. also the chain tensioner bent because of how much compression there is, which is good in a sense but i need to buy a new tensioner now, im a slightly experienced mechanic and i can say that the engine was pretty straightforward to put together and is also made very well. all in all, great buy

Cliff Johnson
Happy so far.

So far good motor. Only issue when I opened the box was the fuel filter was broken. Not the end of the world. Had a couple issues installing the engine on my bike but they were self inflicted. Overall very happy with my purchase so far.

I'm an experienced "shade tree" mechanic. The metals used in this kit as well as the machining and fit are obviously top quality. The paint job resembles a nice car. Also obvious quality. The video available is short and to the point. It tells you the tools needed and breaks install down to simple steps. The Customer Service crew is very helpful. All in all Happy Camper here.

Thomas Keuling

48cc 2 stroke engine kit. It had all the parts, no instructions came with the kit. Found out later could watch a video on how to assembly. Arrived with a damaged fuel tank which BikeBerry replaced with no problems. Not much else to say, it propels the bike very well on level road surfaces, need to use peddle to make it up most of the hills around here.
