After assembly and doing a safety check, you should be ready to ride. However, over time or after assembly you may need to adjust the tension on the belt a little. If you notice either of the following, you may need to adjust the tension on your belt. The steps below, take sometime to get it just right, but with time, it becomes quite easy. 


  • If you apply a lot of torque from a stand still or low speed and you hear a noise and feel the belt slip or skip. It is likely the tension on the belt could be increased. A heavier or stronger rider applying more torque may encounter this and typically adding a little tension will resolve it.
  • If you hear a clicking like noise from your belt when riding or rotating the crank arms when you are not riding, the tension might be too high and you can lower it by taking the steps below.


You can do this by taking the following steps:

  1. Carefully loosen the nuts on either side of the rear wheel. (See pictures below)
  2. Be careful of the motor cable leaving the rear axle when doing this.  
  3. Once both are loose, you can use the screws at the back of the drop out to adjust the tension. Be careful Use the proper sized/fitting screw driver to avoid stripping the screws. (See pictures below)
  4. It will be best to keep track of how much you loosen or tighten the left so you can do the same on the right (For example, 1 or 2 turns, or 2 and a half turns).
  5. If you tighten the screws you will increase the tension in the belt.
  6. If you over tighten it, you may hear the belt clicking as it rotates around the crank wheel.
  7. If you loosen the screws, you will decrease the tension in the belt.
  8. Even if you count the turns perfectly in quarter increments, you may need to make some small final adjustments as you tighten the nuts on the rear axle.
  9. As you adjust these screws at the drop outs and when you tighten the nuts on the rear axle, you must make sure you wheel is properly aligned so it does not rub the chain stays. 
  10. You may have to alternate from left to right with the axle nuts before fully tightening them in place. You may have to loosen them a little to adjust the screws at the drop outs again if the wheel shifts left or right near the chain stays. Once adjusted properly and centered you can tighten the nuts fully.





Alternatively, an aftermarket product, called a snubber, can also help ensure the belt skips less often or not at all. This is one example, however it will need to be modified (removing the notch on the left in the picture below and enlarging the hole next to the notch to fit the axle and 1 additional washer for proper spacing) : Belt Drive Snubber

If you are having difficulty getting the tension just right, you can invest in a tool to measure the tension or invest in a snubber. The snubber prevents skipping of the belt on the rear sprocket by minimizing the belts range of motion.
