The Roadster V2 drive train uses a Top-Trans, Poly-V, high tensile polymer automotive grade belt. With proper care, these belts can last for tens of thousands of miles. Advantages of using a Top Trans belt drive:

  • Increased lifespan
  • Reduced maintenance cost
  • Consistent performance
  • Resistant to oil and no rusting


While they are easy to maintain and clean, there are some best practices for certain scenarios.

Cleaning your belt is often as easy as rinsing the belt with water. Of course you want to avoid spray water on the motor cable as it exits the axle and the connection on the chain stay. Cleaning should not be needed often and is really based more on how often you ride and in what type of conditions.

If you are riding in dry, dusty, dirty conditions often, a common noise for a dry belt to make is a low pitched creaking sound. The sound will typically worsen when the belt is under load, as in starting from a stop or going up a hill. If you are noticing this, you could clean the belt or you could add some lubricant. This will generally last hundreds of miles in those conditions or until it is washed off. We recommend trying a minimal amount, then testing to see if it has quieted. If not, you can add some more until the belt is operating quietly.
