Purpose-built for urban mobility: <2kg ultra-light chassis for nimble maneuvering 60Nm smart assist—smooth acceleration from stops, effortless hill climbs Silent operation + seamless power delivery for elegant daily commutes
Urban e-bikes face a unique set of challenges: frequent stop-and-go motion, noise sensitivity on paved streets, and anxiety over limited range. The PREETO eCity mid-drive motor answers these with a compact 1.95kg design and 60Nm of torque, creating a drive system engineered for agility, silence, and endurance in modern city mobility.
PREETO eCity motor is calibrated to deliver 60Nm of precisely tuned torque, ideal for quick starts and urban gradients. The system can reach peak torque in just 0.2 seconds, providing instant acceleration and seamless integration with the rider’s pedaling.
Engineered for quiet commutes, the motor adopts an innovative gear tooth profile that reduces operating noise by up to 5% under comparable load—bringing the ride experience closer to the natural silence of a traditional bicycle.
Lightweight design is at the core of the PREETO eCity system. A segmented stator enables high output in a compact form, while the magnesium alloy housing reduces overall weight by 30% compared to aluminum. The total system weight is kept under 1.95kg, making it one of the lightest in its class.
PREETO’s proprietary gear machining achieves up to 99% efficiency in single-stage transmission, translating into a 10% range improvement under the same battery capacity. And thanks to its freewheel-friendly structural design, the motor creates minimal drag when unpowered, allowing the e-bike to ride more like a conventional bike—ideal for low-battery scenarios or pedal-only operation.
