[Chain & Chain wheel] - are responsible for:

 The connection between the engine and the rear wheel.

 Adjusting the max speed of the scooter:

 You kneed to know first what is the RPM (Revolution Per Minute) of your engine - lets call it X.

 Now you kneed to know the RPM of the rear wheel lets call it Y. Y=X*R1/R2 (R1 -the radius of the engine wheel, R2 -the radius of the rear wheel).

 The speed of the scooter is then (let call the speed S): S=Y*2P*R2.

 Adjusting the power of the scooter, the faster the scooter is the less powerful it is. You must find the proper adjustment for a fast yet powerful scooter!!!.
