*The maximum power you can achieve depends on the motor and battery you are using. The max phase current depends on your motor. See power chart below.

**While Torp controllers are rated IP67, making them highly water-resistant, the wiring harnesses for both the controller and bike are not waterproof. In case your bike is exposed to water in any way, it is mandatory to apply dielectric grease inside all connectors. The warranty does not cover malfunction or damage arising from the use of the motor controllers in activities where frequent or extended submersion in water is expected, such as riding in streams, rivers, or flooded areas. Over time, seals and components may degrade, reducing the water-resistant effectiveness of the product. Damage resulting from this natural wear and tear is not covered by the 2-year warranty.
