## Description

Belt Drive Driving Sprocket Assembly for 49cc 60cc 66cc 80cc 2-Stroke Motorized Bike Gas Motor Bicycle

Review: I ended up reselling this - Tried on three different occasions to get this to work belt slipped right off there was no lip to hold the belt in place. Looked up other manufacturer designs and they weren't like this they have lips on them. So I figured this product would just put it lips on me.
Review: Nice setup compared to chain - I really like this instead of a chain. Much more quiet and smooth. Its been a bit challenging to adjust right without rubbing my frame but is worth the work. I really prefer belts over chains after this purchase.

## Features

- Fitment: For 66cc 80cc Motorized Bike.
- Package include: 1 x Drive Pulley Diameter: 39mm (11-12T sprocket equivalent) 1 x Rear Wheel Pulley Diameter: 190mm (50T sprocket equivalent) 1 x T-Belt Type: 5M-1350; Perimeter: 1350mm; “Teeth” Count: 270
- Smooth acceleration: The T belt has the advantage of putting down the torque of the engine much more smoothly and gradually than the chain drive counterpart. Using a belt driven motorized bike you won’t feel a sudden tug when you twist the throttle, just smooth acceleration.
- Easy to maintain and clean: T-belts also do not accumulate dust or dirt and need far less maintenance - like lubrication - when compared to chain driven design.
- Little noise: No more noisy metal chain. The belt driven design emits very little noise while in use.

### ⭐ Junk
*by R***T on December 30, 2022*

Idler pully has wrong bearings on it. If you tighten pully against bracket, pully does not turn. The pully MUST be tight, otherwise the belt skips.
