The LVBU MRT Series features a built-in cassette torque sensor — delivering a mid-drive-like riding experience in a compact rear hub motor. Real-time pedal force measurement enables smooth starts and consistent, responsive acceleration.
High-Strength Aluminum Alloy Housing
Precision spray-finished surface for superior scratch resistance and an environmentally friendly manufacturing process.
Motor Structure
► Cassette — Built-in Torque Sensor
The torque sensor is integrated directly into the cassette, measuring your pedal force in real time so the motor responds instantly to every stroke.
► Coil — Machine Winding
Automated machine winding ensures high consistency and precision across every unit.
► Steel Sheets
Silicon steel laminations for efficient magnetic flux and reduced core loss.
► Magnets
20 high-strength permanent magnets for powerful and stable torque output.
► Reduction Gears
PA66 nylon reduction gears — cold and heat resistant, high toughness, and low friction coefficient for quiet, long-lasting operation.
4 Integrated Sensors
The MRT motor combines four precision sensors to deliver intelligent, adaptive power assist.
 |
Cadence Sensor
12-magnet high-precision cadence sensor for smooth, real-time pedaling detection.
|
 |
Cassette Torque Sensor
Built-in highly sensitive torque sensor measures pedal force in real time for natural, proportional assist.
|
 |
Temperature Sensor
High-precision thermal protection — automatically limits power to prevent overheating.
|
 |
Speed Sensor
Real-time speed monitoring ensures smooth, comfortable power delivery at every pace.
|
High Cadence Sensitivity
The integrated high-sensitivity cadence sensor monitors pedaling speed in real time, allowing the assist system to respond fluidly to changes in rhythm.
High Torque Density
Compact design with an exceptional power-to-weight ratio — more torque from a smaller, lighter package.
High-Strength Motor Shaft
Engineered for durability under load, the reinforced motor shaft handles demanding terrain and riding conditions reliably.
IP65 Waterproof Rating
Sealed to IP65 — protected against dust ingress and low-pressure water jets, suitable for all-weather riding.
High-Quality Waterproof Cable
9-pin waterproof connector: 3 phase wires, 5 Hall sensor wires, and 1 signal wire — clean and reliable wiring for DIY builds.
Wide Wheel Size Compatibility
Fits most standard wheel sizes: 16", 20", 24", 26", 27.5", 29", and 700C — suitable for a wide range of bike frames and styles.
