The 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 into the street-legal ride of your dreams. No more pedaling up steep hills or charging a battery only for it to die halfway through your commute. With the (engine) you’ll get to where you need to go and back with ease. (All specifications are subject to change - open your kit to verify contents.)
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.

The Flying Horse 66/80cc bicycle engine measures about 8.5in.x 7in.x 5in. (HxLxW). These engine fit standard men’s bicycle frames with tubing of 25mm to 29mm in diameter, and around 10in. of clearance from the cranks to the top to be of the frame. Larger frames may require modification to the frame in order to fit an engine.
The engine chain does not interfere with your current drive chain and peddling because it rides on the opposite side of the bike sprocket.
Installation is a breeze! The rider only needs some basic hardware skills, tools, and around 2-3 hours for installation and fine tuning adjustments (Note: Seller is not responsible for misuse or this kit or any warranty after installation).
Fits Most 26" Wheeled Bikes (Mountain, Cruiser, Chopper, Road) with V-frame. The frame should have 9-11” of clearance between the bottom bracket and top bar, and the diameter of the frame tubes should be 25-29mm (around an 1”).

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.
