Browse for sprockets by vehicle make and model.

Freewheel Clutch Test

To test a freewheel clutch simply turn the scooter or bike on and accelerate the throttle a little. If the chain moves and the rear sprocket spins but the back wheel does not move then the freewheel clutch is defective. For tips on how to remove the old freewheel clutch please visit the freewheel clutch removal page.

Electric Scooter Repair Help | Electric Scooter Laws | Dealer Discounts | Feedback | About Us

 

We have a wide variety of freewheel clutches for electric; scooters, bicycles, dirt bikes, pocket bikes, chopper bikes, and go karts. Our freewheel selection includes left hand thread and right hand thread freewheels and freewheel mounting nuts and bolts. Freewheel clutches allow the rear wheel to spin freely without resistance from the motor when the vehicle is coasting, going downhill, or being pushed or pedaled. This increases the efficiency of the vehicle and gives it a longer range on a single charge of the battery pack. Freewheel clutches take a lot of abuse because the the entire power load of the motor is on them whenever the throttle is engaged so they are one of the parts that need frequent replacement.
