Unlock smoother power and stronger performance on your Ultra Bee
The Torp TC1000 2.X is a high-performance FOC motor controller (inverter) designed specifically for the Sur-Ron Ultra Bee running a TM50 Speed or TM50 Pro motor. It’s a direct aftermarket replacement for the stock Ultra Bee controller, built for riders who want sharper throttle control, higher efficiency, and more tuning options—without guesswork.
With built-in Bluetooth and an easy-to-use iOS/Android app, you can configure ride modes, calibrate the system, and fine-tune response to match how (and where) you ride—trail, enduro, or fast open terrain.
Key benefits
- FOC control for precise current control and excellent ride feel (up to 99% efficiency)
- Serious current headroom: max 700 A battery current and max 1000 A phase current*
- Up to 58 kW* potential power (depends on TM50/TM50 Pro motor and battery setup)
- Built-in protection algorithms: overcurrent, overvoltage, undervoltage, and overheating protection
- Stock BMS communication supported for Sur-Ron Ultra Bee systems
- Multiple ride settings: choose different throttle response and regenerative braking modes
- IP67-rated controller body* for water/dust resistance (note: harness connectors are not fully sealed)
App control (Bluetooth) for quick setup
Dial in your Ultra Bee from your phone. The Torp app (iOS & Android) enables setup and calibration, helping you get a clean, predictable throttle and optimized regen behavior for your riding style.
Sensor & sensorless support for TM50 setups
The TC1000 2.X supports both sensored control (Holo (Hall) / encoder) and sensorless control. That flexibility makes it a strong choice across different TM50 configurations on the Sur-Ron Ultra Bee platform.
Compatibility
- Bike: Sur-Ron Ultra Bee
- Motor: TM50 Speed or TM50 Pro
