Low-Step Design for Everyday Accessibility
Rumble 2.0 combines a low-step 6061 aluminium frame with an adjustable saddle, making mounting and dismounting easier for daily commuting, errands and leisure rides. The integrated rear rack adds practical carrying space without requiring a separate rack installation.
250W Rear Motor with 65Nm Torque
The 48V 250W brushless rear hub motor delivers up to 65Nm of torque to support starts, inclines and changing road conditions. Shimano 7-speed gearing provides additional mechanical control, allowing riders to select an appropriate gear for flatter roads and gradients.
Torque Sensor for Precise Assistance
The torque sensor measures the force applied to the pedals and adjusts motor assistance according to rider input. Lighter pedalling receives moderate support, while stronger pedal pressure increases assistance, creating a direct and responsive connection between rider effort and motor output.
Removable 48V 18Ah Battery with up to 100km Range
The removable 48V 18Ah battery provides an assisted range of up to 100km under favourable conditions. It can be removed for convenient indoor charging, while the 48V 3A charger provides a typical charging time of approximately 6–7 hours. Actual range varies with rider weight, cargo, terrain, temperature, tyre pressure, assistance level and riding style.
Wide Tyres, Front Suspension and Hydraulic Brakes
Chaoyang 20" × 4" wide tyres provide a large contact area for stability and cushioning on city roads, gravel and uneven surfaces. An adjustable oil-and-spring front fork helps absorb impacts, while fully hydraulic disc brakes with 180mm rotors front and rear provide progressive and controllable braking.
Integrated Equipment for Daily Riding
A 3.5-inch colour LCD displays speed, battery level, assistance mode and trip information. The integrated LED headlight and rear light with braking function improve visibility, while the built-in rear rack provides useful carrying capacity. Rumble 2.0 weighs approximately 31.9kg with the battery and supports a maximum load of 150kg.
