Designed around SOTION's powerful FW01 mid-drive motor, this kit replaces the factory swing arm and motor assembly with a purpose-built performance package capable of handling serious power levels while maintaining reliability.
Built for Big Power
At the heart of the kit is the SOTION FW01 motor, a high-performance mid-drive unit rated at 13kW continuous powerwith a staggering 26kW peak output. The motor is designed for 72V systems and produces up to 65 N·m of peak motor torque, making it a substantial upgrade over the stock powertrain found on most Tuttio and Kugoo platforms.
Key Motor Specifications:
✅ 72V Operating Voltage
✅ 13kW Continuous Power
✅ 26kW Peak Power
✅ 65 N·m Peak Torque
✅ Up to 800A Peak Phase Current
✅ 9,000 RPM Maximum Speed
✅ Encoder Position Sensor
✅ IP67 Water Resistance Rating
✅ 93%+ Maximum Efficiency
✅ Natural Air Cooling
Designed to Handle Serious Abuse
One of the biggest advantages of the FW01 setup isn't just the motor—it's the swing arm itself. The reinforced design is built specifically to manage the increased torque and acceleration that high-powered builds demand. Compared to stock components, the SOTION swing arm provides the strength, rigidity, and chain alignment necessary for high-output controllers and upgraded battery systems.
Whether you're chasing top speed, hard launches, wheelies, or aggressive off-road riding, this kit gives riders a much stronger foundation for pushing performance to the next level.
Real-World Performance
The FW01 platform has quickly gained a reputation among performance builders due to its ability to support massive power levels while remaining smooth and controllable. Riders running the FW01 system have reported speeds exceeding 60 mph with properly configured battery and controller setups, while still leaving plenty of headroom for future upgrades.
Unlike many bolt-on upgrades that simply add power, the FW01 kit upgrades the entire drivetrain package, creating a more balanced setup that can better withstand repeated high-load riding.
Reliability Meets Efficiency
With an efficiency rating above 93%, the FW01 converts more battery power into forward motion and less into wasted heat. The motor also features an IP67 protection rating, making it resistant to dust and water intrusion for riders who frequently encounter dirt, mud, or wet conditions.
The included encoder-based position sensing provides precise motor control, resulting in smoother throttle response, stronger low-end torque delivery, and improved overall rideability compared to traditional hall-sensor-only systems.
Who Is This Kit For?
The SOTION FW01 Swing Arm Kit is ideal for riders who:
- Want substantially more power than a stock Tuttio or Kugoo can provide
- Are building a high-performance 72V setup
- Plan to run larger batteries and advanced controllers
- Need a drivetrain capable of handling 20kW+ power levels
- Want a stronger swing arm and motor package for aggressive riding
Final Thoughts
The SOTION FW01 Swing Arm Kit isn't just an upgrade—it's a complete drivetrain transformation. Combining a reinforced swing arm with a 13kW continuous / 26kW peak motor, encoder technology, IP67 protection, and excellent efficiency, this kit delivers the strength and performance needed for serious electric pit bike builds. For riders looking to unlock the full potential of their Tuttio or Kugoo platform, the FW01 is one of the most capable upgrades available today.
