Our Adjustable belt drive is our new self tensioning belt drive system. A perfect upgrade to never wanting to tension your belts time after time again. It will never set the tension too tight or too loose but just right. 

This belt drive uses HTD5m-405mm belts as opposed to the original motor mounts (non-self adjusting). These motor mounts are not compatible with our Over Engineered Belt Guards.

To adjust just loosen the two screws holding the mount and it will spring up. Re-tighten to keep the tension.

Note: To use Smart Brake lights with the adjustable belt drive, please note that they require the New rear mounting brackets or to buy a full new set here

Recommendation Note: You should be using 18t motor pulleys as a minimum for the adjustable belt drives as you can get belt skips going below 18T. 

PLEASE NOTE if you don't already have a motor pulley nor a wheel pulley (for MBS rims), you will need to purchase those separately as well. If you need a 72T pulley for HyperRims™, contact [email protected]
