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.

Seller is not responsible for injuries and/or damages resulting from operating this motorized bicycle or bicycle engine 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.

Great kit for an old guy like me.

This is a great kit if you do not want to deal with a clutch and pedal start. The kit is a little harder to install than the 2-stroke pedal start kits but
nothing over the top. I added the proformance pipe but had to cut and weld to make it fit. I also was not crazy about the provided battery holders
so I did my own thing. It runs good right out of the box with no carb jetting. I would definitely purchace this kit again.

Highly recommend

My first engine was a Chinese kit from Amazon, it worked very well, only thing I didn't care for was the pop starting it was a pain. Having to pedal and balance the bike while working the clutch and choke. So I found this electric start kit. Assembly is easy if you understand basic mechanics. This kit comes with everything you need to get started, minus the fuel. I've riden the bike for a couple years now. Only thing I've changed was the rear sprocket because 1. I don't want to pedal and 2. I live where there is a lot of hills. But the included rear sprocket is ok for majority of riders with balance of power and speed. The electric start option with pull start backup is the best set up so far!
