Description Installation
The new Balanced Jet line of motor kits raise the bar on the quality of the china girl. With a factory balanced one piece 40mm crank, this motor will out of the box have: more power, less vibration and last longer. Overall you will have less maintenance issues and a smoother running ride. Equipped with a New Speed V2 carb, with a larger diameter slide for more fuel. The new V2 also removed the unneeded fuel valve and replaced it with a large fuel inlet for better fuel delivery. Also included is a 41 tooth rear sprocket to give you more top speed. This is one of the best built stock kits we have ever seen.

All our motorized bicycle engine kits comes with everything but the gas and oil. Convert your men's 24" - 26" bicycle to a 20-40 MPH and 100-150 Miles per gallon machine. 2 Stroke Motors require oil mixed in with the gas. 16 to 1 (8oz per Gallon) when motor is new and 32 to 1 (4oz per Gallon) after break in period (about 1 or 2 tanks).

You can still pedal bike like normal with clutch lever held in or locked in with button. To start a 2 Stroke Bicycle Motor just hold in the clutch and pedal to get some speed then release the clutch to "Bump Start" the motor and off you go. To come to a stop once engine is running you can hold in clutch and engine will idle. Push Kill Switch on throttle to kill motor, clutch must be held in when bike is in motion or motor will keep running.

Engine kit will add about 24 lbs to your bike. Fits most standard V frame Men's 24" and bigger, we suggest 26". Engine kit is about 8.5" height 7" length 5" width. Kit fits on standard 25mm - 29mm frame tube.

  • China bike engine factories have always advertised their biggest engine as 80cc. However, the bore and stroke of an 80cc being 47x38mm only equals 66cc. Therefore there is no such thing as an 80cc Chinese bicycle motor and it truly does not exist. This is the biggest motor available.
