The BBR Tuning 2-Stroke 66/80cc Bullet Train Electric Start Engine Kit is an ideal upgrade for experienced builders ready for more speed and a higher level of performance.
Please note: Sprocket Clamp Assemblies included with Bullet Train 66/80cc, 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.
Also note: Due to the design of this engine, most parts (including cylinders, pistons, cranks, and gaskets) and performance upgrade parts (including upgraded mufflers, carburetors, cylinder heads, and case covers) do not fit on this engine. DO NOT purchase parts or performance upgrades designed for non-electric start 2-stroke bicycle engine kits
Attention: This kit does not come included with a bottom bracket assembly. If the bicycle you are converting has a 1-piece crank, you will need to purchase a Bottom Bracket Assembly. If your bicycle has a 3 piece crank, you may not need this piece. However some bicycles with 3 piece cranks may not be compatible with the wide crank assemblies included with this kit.

Disclosure of accurate engine size: While we have chosen to use the long standing factory branding engine size of "80cc", the true displacement of the bicycle engine is 66cc. Down through the years China bicycle engine manufactures have advertised their biggest engine as 80cc, therefore we have listed them in the same way on our website. However, the bore and stroke of an 80cc being 47x38mm equals 66cc. Therefore the true displacement of the 80cc bike motor is 66cc. In the west, the volume of a cylinder is calculated by using the formula Volume = Pi x Radius Squared x Stroke. However,in the east the displacement of an engine includes the area of the cylinder head's combustion chamber as well as the volume of the cylinder. Therein lies a discrepancy between measuring standards by the manufactures in China with those in the United States. However, all "80cc" engine kits on the market today are actually 66cc in displacement size if measuring by US standards.

Customer Reviews
I've been riding motorized bikes for awhile and this motor beats anything I've rode. There's plenty of speed and I love the electric start I'm 62 years old and pedaling a bike to get it started is pretty rough. But hands down this is the best I've had so I would recommend it to anybody that has experience with these bike's. I will tell you look close at the kits picture because that's what your buying the kit don't come with the bottom crank or battery you will have to buy that yourself I think I paid $25 for the battery and $22 for the crank. But again this is well worth your money I had to mount my battery just behind the seat
Very Good excelente
I love it, So far have bought three of them. One for my boyfriend, daughter, and me. Easy to start, runs good. Not hard to put together.
So this engine is a lot wider then a normal engine. Which is expected but should be noted. I’m guessing it’s as wide as a four stroke. I couldn’t find a tutorial anywhere so if you’re a new builder like me go try something else first, which is the reason for the low rating. Parts seem pretty quality though.
The parts I got are indeed good quality parts, but nowhere on the website does it specify wether or not they can be fitted with custom parts. After over 30 minutes on hold, I was told that I would be responsible for shipping the engine back myself, (including costs), and that the refund of the difference would only be in store credit. The act of returning these parts would have ended up costing more money than the refund itself. Again, the parts themselves are good quality, but there is a clear lack of specification on the website and customer service on the phone. In the end I WILL use the engine and I like it a lot but their customer service needs to be improved
