• Powerful Mid Drive Motor with Torque Sensor: 750 watt of smooth, silent power, 130 Nm of hill-crushing torque 2026 upgraded VSM01 mid drive motor with torque sensor delivers instant, natural assistance up to 27 mph (43 km/h) with greater than 80% efficiency so you fly up grades instead of grinding
• Four Versatile Ride Modes: Fire up throttle-only for effortless cruising, switch to torque-sensing assist for natural pedal support, engage walk-assist to push the bike at 3 mph while loaded. A finely-toothed freewheel cuts engagement angle to under 3 degrees, so every pedal stroke translates to instant, jerk-free power the moment your foot moves
• Ride-Saving Redundancy System: If the internal Hall sensor ever fails, VSM01 instantly switches to sensorless mode and keeps the motor spinning so you will never be stranded halfway up a mountain or miles from home; traditional motors simply cut out and leave you pushing
• Superior Cooling and Water Resistance: IP66-rated aluminum housing blocks dust, while oversized heat fins and an internal thermal pad pull heat away from the windings so core temps stay below 104 degrees F (40 degrees C) even when you are grinding up a 15% grade in 100 degrees F desert sun, meaning sustained peak power, no thermal cut-outs, and a motor that is ready for the next ride the moment you are
• Complete Bolt-On Conversion Kit: 5-level assist with fixed chainring, brake sensors, cranks, headlight, color display, throttle and speed sensor all included, zero extra shopping, ready to electrify your bike in one box
• Universal Bottom Bracket Compatibility: Designed to fit standard bottom brackets ranging from 68mm to 73mm (2.68 to 2.87 inches), making installation straightforward on most bicycle frames without requiring special adapters or modifications
• Integrated Controller and Torque Sensor: Controller is fully integrated into the motor housing along with the torque sensor, providing power assist ratio from 36% to 300% based on how hard you push on the pedals for a natural riding experience
