Flying Horse is here to bring you the engine kit market’s first US Environment Protection Agency (E.P.A.) approved bicycle engine kit! The Flying Horse 66/80cc EPA Approved Black Angle Fire 2-Stroke Bicycle Engine Kit is here for any rider looking to strap a motor on their beach cruiser, mountain bike, or road bike and turn it in to the street-legal ride of your dreams. No more pedaling up steep hills or charging a battery only for it to die half way through your commute. With the (engine) you’ll get to where you need to go and back with ease.

Introducing the Market’s Only EPA Approved Engine Kit

2-stroke engines are notorious for putting out lots of exhaust filled with oil and fuel, which is why most cannot be used on the road. Compliant with EPA emissions standards, the specialized muffler included offers a catalytic converter with precious metals that help clean that exhaust coming from this engine, making them EPA approved for public use. Coupled with this ability to run a mere 1:100 ratio of gas to AMSOIL SABER Professional Synthetic 2-Stroke oil, this engine is sure to keep emissions as low as possible. Not only is a cleaner motor better the evironment, you'll feel your motor run a better than other motors out there.

Brand New Motor, Same Great Flying Horse Quality

Just because these engines are compliant with emission standards, it doesn’t mean these engine’s don’t tear up the track, trail, or streets like any awesome motor. Not only do these engines still get you up to 25-35 mph and up to 150 MPG fuel economy, they also come with the 66/80cc High Performance Carburetor to give it that extra boost of power and speed.

Of course, no motor would be useful without a balanced crank and upgraded crank bearings. This motor boasts superior crank components and balance over other engines on the market, and this clutch will make sure your motor engages and disengages smoothly. With its all-terrain rear drive sprocket, you better believe this engine kit was meant for anyone looking to use their motor as their main mode of transportation.

As always, each Flying Horse bicycle engine kit comes with an industry leading 6 month parts-exchange warranty

Gasoline operated products are NOT compliant with California Air Resources Board (C.A.R.B) for the use on/off Public roads. Due to C.A.R.B. restrictions orders shipped within California will be canceled and refunded.

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.
