LVBU MRT je převodový zadní nábojový motor s vestavěným kazetovým snímačem točivého momentu — jízdní zážitek na úrovni středového motoru ve formátu nábojového motoru. Měří sílu šlapání v reálném čase pro plynulou a citlivou asistenci. Lehká hliníková skříň, IP65, 4 integrované snímače (točivý moment, kadence, teplota, rychlost), redukční převody PA66 a kompatibilita s velikostmi kol 16"–700C.
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.
Precision spray-finished surface for superior scratch resistance and an environmentally friendly manufacturing process.
The torque sensor is integrated directly into the cassette, measuring your pedal force in real time so the motor responds instantly to every stroke.
Automated machine winding ensures high consistency and precision across every unit.
Silicon steel laminations for efficient magnetic flux and reduced core loss.
20 high-strength permanent magnets for powerful and stable torque output.
PA66 nylon reduction gears — cold and heat resistant, high toughness, and low friction coefficient for quiet, long-lasting operation.
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. |
The integrated high-sensitivity cadence sensor monitors pedaling speed in real time, allowing the assist system to respond fluidly to changes in rhythm.
Compact design with an exceptional power-to-weight ratio — more torque from a smaller, lighter package.
Engineered for durability under load, the reinforced motor shaft handles demanding terrain and riding conditions reliably.
Sealed to IP65 — protected against dust ingress and low-pressure water jets, suitable for all-weather riding.
9-pin waterproof connector: 3 phase wires, 5 Hall sensor wires, and 1 signal wire — clean and reliable wiring for DIY builds.
Fits most standard wheel sizes: 16", 20", 24", 26", 27.5", 29", and 700C — suitable for a wide range of bike frames and styles.
