THIS COMESIN2 PACKAGES. IN MOST CASES, THE ENGINE KIT WILL BE DELIVERED FIRST, THEN THE BICYCLE THE NEXT DAY OR TWO.
Convert your bicycle to a motorized bicycle by adding a 2 stroke engine kit to it. The kit fits best on bikes with 25 to 30mm diameter front down tube and 70 degree Vee type frame like a mountain bike but can be installed on larger diameter tube frames with modifications. “Looks Cool” on the older beach cruiser type coaster brake bikes. The motor bolts to the bicycle frame in the center of the frame (additional mounting options available). A second Heavy Duty chain is attached from the motor to the rear wheel via a second sprocket attached to the rear wheel.
Starting:
2 stroke motor kits are started by “bump” starting them. While holding in the clutch, pedal the bike quickly. When you release the clutch after the bike gets to speed, it push starts the motor.
The kit will average around 25-35 M.P.H depending on rider weight and rear sprocket gear ratio.
Gas Mixture
This bike motor kit comes with everything that you'll need except gas and oil since this is a 2 stroke, 2 stroke oil needs to be added to the fuel. Always mix gas in a gas can, not the gas tank. When the engine is new, it would need to be broken in with a richer mixture, after at least 1 tank of gas, then the mix can be “leaned out” (less oil). Never go less than 32:1 ratio (4oz of oil per Gallon).
New Motor - 16:1 (8 oz of oil per gallon)
After Broken in - 32:1 (4 oz of oil per gallon)
You will be able to stop or start the engine as you ride. This kit gets maximum fuel efficiency stock at around 100 miles per gallon.
The Motor will require some assembly, the top end of the motor must be installed.

We Cannot ship to PO BOXES at this time. Through UPS we offer many shipping methods and for International and Canadian shipping we suggest UPS STANDARD, (2-6 days; does not cover Customs Brokerage, Duties, and Taxes… these are charged to the consignee on delivery). We have found that this is the cheapest way to send packages to Canada.
Gas And Oil Mixture For Fuel Ratio: (Use of a synthetic 2 stroke oil is recommended.)
The bicycle motor engine kit is a 2 cycle design, therefore, a gasoline/oil mixture is necessary. During the break-in period (1st 4 tanks of fuel, the ratio is 16 to 20 parts gasoline to 1 part 2 cycle oil. After the break-in period, the ratio is increased to 20 to 25 parts gasoline to 1 part oil. The engine crankshaft bearings are lubricated from the oil in the gas mix. A rich break in oil mixture ensures bearings will not cease during engine break in period.
Skills & Experience:
The buyer may need some basic hardware skills, tools, and it takes roughly around 2-3 hours to install and to do some adjustments and fine tuning.

We make no guarantee as to the road legality of these bike motors.
Disclaimer: Down through the years China bike engine factories have always advertised their biggest engine as 80cc therefore we have listed them the same way on our website. However, the bore and stroke of an 80cc being 47x38mm only equals 66cc. Therefore there is no such thing as an 80cc bike motor and it truly does not exist and we want to make sure that you are aware of this.
