It is important to know that although this kit comes equipped with an assembly motor, a carburetor, and an exhaust, and other parts like the transmission are not a part of the kit. But the good news is, that the parts that are involved are readily compatible with transmissions that are manufactured by other brands.
What this means is that if you are already in possession of a transmission or if you would rather buy a transmission from another brand, the motor will still work. Another thing is, this kit would make a great replacement kit, that is if you so wish to replace any of the listed parts.

The first is, what is your bike’s wheel cycle? Some kits can fit only 26 inches or a 28 inches-wheeled bike. Others can fit a 24 inches-wheeled bicycle. You should always check to know if your bike meets the wheel cycle requirement before you buy.
