  • 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. You won’t feel a sudden tug when you twist the throttle, just smooth acceleration
  • Package include: 1 x Drive Pulley Diameter 39 mm (11-12T sprocket equivalent); 1 x Rear Wheel Pulley Diameter 190 mm (50T sprocket equivalent); 1 x T-Belt Type 5M-1350; Perimeter 1350 mm; “Teeth” Count: 270
  • 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

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.

i love the kit, but the rear sprocket is so big it doesnt fit the narrow width frames or it rubs on the rear frame and makes a big hassle... also u cant tighten up the front sprocket all the way or it hits the case and doesnt turn one bit, so have to leave it semi loose and use lock tight and hope it holds.... still better than the original chain drive, at least if it breaks it wont take out the cases of your motor!!!!

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.

I did like the fact of buying belt for my motorized bike but if you have a schwinn chopper bike do not get this one it will not fit you need a longer belt and the lineing is off if you try to move ur mounting plate. And Amazon will not just send you a belt you have to send ever thing back and try and guess what it would be. That's b.s. in my book. But other tgen that happy riding everyone...

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.

I like the product , I only wish it came with a little instruction and or a sprocket hub adapter . Since I received the belt and put on ,my bike has been down ! 😓 when I parked it because of broke chain and ordered belt drive because I was tired of hassle with chain , the clutch drive pulley is rather large and tight fit but works ,I can’t wait to get it all good again 😓 . The customer service for this outdoor power equipment was absolutely outstanding! Awesome !
