ZB 80JET BLACK SLANT DESIGN ADVANTAGES :
- JET 80CC SLANT ENGINE
The strongest bicycle racing engine out there. This engine features a 45 degree angled spark plug and include a steel intake manifold, with a larger inner diameter for improved performance. This engine has a 1 3/8 (1.375) inch diameter downtube engine mount accomodating the most common bicycle frames. Higher grade nuts and bolts are used throughout the entire engine.
- HIGH QUALITY FUEL LINE
Improved fuel line quality is included with these kits that don't get hard over time.
- IMPROVED GAS TANK FASTENERS AND MOUNTS
Strong gas tank clamps are now packaged which help create a secure bracket mount for the gas tank to the frame of the bicycle. The gas tank mounting bolts measure 1 1/8 (1.125) inches long and a spring loaded gas tank cap is included.
- NEW DESIGN IDLER PULLEY WITH ROLLER BEARINGS
Stronger and more durable idler wheels, and a quieter and more fluid roller system.
- THE LATEST RACING MUFFLER WITH LEG SHIELD & CLAMP
The hemispherical (half-circle) endcap and larger exhaust pipe diameter make for a smoother-running, more powerful engine. These mufflers are heat shielded to prevent your leg from coming in contact with the muffler. A clamp for holding the Exhaust Muffler to the frame of the bike is included with this package.
- LARGE FRAME TUBE ADAPTER
The large frame tube adapter accommodates up to 2 inch diameter down tubes.
This complete racing bicycle engine kit package comes with every thing that you'll need to put together and build your own racing engine, and proceed to convert any regular 26" single speed or multi speed mountain bike into a motorized bike. You'll 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. Twist grip hand throttle controls speeds from 38 to 53/kmph depending on the gear ratio. This installation kit comes with a 44 tooth 9 hole sprocket with easy to install 9 bolt universal mounting hardware that clamps over the rear wheel hub and spokes. This creates a totally independent drive sprocket and chain that does not interfere with your current drive chain or peddling.
With the built in clutch you maintain full function of the original bike. Pedal, shift, and ride your bike like normal. The engine kit only adds about 20lbs to your bike. When you want to engage the engine simply release the clutch hand lever and the engine springs to life. To power off, simply press the included kill switch.
What do I need to put my motorized bike together?
1. Requires basic mechanics and simple tools (any mechanical experience always helps!) There are a number of Youtube videos and references we offer to help with installation.
2. It takes about a few hours to install while using easy to follow detailed instructions (which can be found on our website at http://www.zoombicycles.com/installation or by copying and pasting that URL link into your browser. If you are unable to download or access the site, please send us an inquiry and we will be happy to send you the details directly.
What type of bicycles with these racing engines fit on?
The racing engine requires a clearance of at least 15 inches in height on the seat tube (the part of the frame under the seat) and 14-15 inches in length on the down tube (the diagonal part of the frame), and it is approximately 5 inches wide. To help with determining whether or not the engine will fit in your frame, we have prepared a template for the engine which can be found by clicking here: Engine Template or by copying and pasting this URL link into your browser: http://www.zoombicycles.com/downloads/engine-template.jpg .
We recommend installing these kits on bicycles with a 1 inch diameter seat tube and with a 1-1.25 inch diameter on the down tube.
We have a gallery available on our website and you'll be able to view a selection of bicycles that these engines have been installed on.

Over the years our manufacturers have advertised their largest sized engines as 80cc engines and therefore is listed in the same manner on our site. However based on the results provided at the time of Displacement Testing and Certification, these engines have been recorded with a true displacement of 66cc being the largest sized among all bicycle engines currently on the market. There are currently no true 80cc engines on the market to date and we want to make you aware of this.
