Unlock smoother power and stronger performance on your Sur-Ron
The Torp TC500 2.X is a high-performance FOC motor controller (inverter) built for riders who want sharper throttle response, better efficiency, and reliable power delivery on the Sur-Ron Light Bee platform and the TM25 electric motor. Designed for modern 22S battery setups, it supports 60–80 V nominal packs (up to 92.4 V fully charged) and delivers serious current capability for aggressive trail, enduro, and track-style riding.
Why riders choose the TC500 2.X
- FOC control for refined ride feel – Field-Oriented Control manages motor current precisely for smoother acceleration and more controllable torque.
- Built for 22S builds – Supports 60–80 V nominal battery systems (22S) with 92.4 V fully charged voltage.
- Up to 25 kW max power (TM25) – When paired with a TM25 motor, the system can reach up to 25 kW maximum power.
- Clear limits with OEM motors – With the stock SurRon motor, max power is 17 kW; with the stock Talaria MX4 motor, max power is 18 kW.
- High current capability – Up to 350 A battery current and 500 A phase current limit.
- Hall/sensored + sensorless operation – Works with a Holo (Hall) encoder and also supports sensorless mode.
- Bluetooth + mobile app tuning – Connect via Bluetooth and adjust settings in the Torp app on iOS & Android.
- Pre-calibrated setup – Ships pre-calibrated, so no extra calibration steps are required.
- Up to 99% efficiency – Designed for excellent electrical efficiency and reduced losses.
App control and connectivity
Dial in your ride with Bluetooth connectivity and the Torp mobile app (iOS/Android). The TC500 2.X also supports BMS communication, making it a smart choice for riders upgrading to higher-voltage packs and wanting better integration.
Water resistance notes (read before wet riding)
The controller itself is rated IP67, meaning it’s highly resistant to water and dust. Important: the wiring harness and the bike’s OEM connectors are not waterproof. If your bike is exposed to water, it’s strongly recommended to apply dielectric grease inside the connectors to reduce corrosion and moisture-related issues.
