⚠️WARNING This vehicle is for private use only. It is NOT authorised for use on public roads, cycle paths or pedestrian areas. Do NOT modify the controller, firmware or battery to increase speed or power. Any modification cancels conformity and warranty and presents fire and crash risks. Always wear a helmet. Check brakes before every ride. Battery hazard: risk of short circuit and fire. Do not disassemble, puncture or expose to temperatures above 50 °C. Do not charge unattended. Power System: 250W Rear Motor and 48V 20Ah Battery
The rated 250W rear-drive motor delivers a maximum torque of 55N·m, with pedal-assist limited to 25 km/h and throttle limited to 6 km/h, fitting the regulatory framework for electric bikes in many regions. The 48V 20Ah (960Wh) lithium battery supports 75–100 km of range, with a charging time of about 8H, suitable for daily commuting and weekend medium-to-long trips. The cadence sensor works with the Shimano 7-speed system, allowing riders to adjust cadence and assist output according to road conditions. The LCD display provides speed, battery, and assist level information, helping riders monitor the vehicle's status.
Handling and Braking: Hydraulic Disc Brakes and Drivetrain
The hydraulic disc brake system provides relatively stable braking force on wet or long downhill roads, and together with the grip of the 20×4.0 inch pneumatic tires, it improves braking controllability. The Shimano 7-speed drivetrain covers flat cruising and gentle slope riding needs, and riders can adjust gears to match different cadences. The front suspension has 40mm travel with no rear suspension, absorbing part of the road impact on gravel roads and speed bumps. The frame uses aluminum alloy, balancing structural strength and corrosion resistance at a curb weight of 33.2 kg.
Range and Charging: Practical Boundaries of the 960Wh Battery
The 48V 20Ah battery has a capacity of 960Wh, with official range of 75–100 km; actual mileage is affected by load, road conditions, assist level, and temperature. The 8H charging time suits overnight or office-hour replenishment, and the 960Wh capacity sits at a higher level among comparable models. The assist limit of 25 km/h and throttle limit of 6 km/h give the vehicle clear regulatory boundaries in different usage scenarios. A maximum climbing angle of 15° provides basic capability for urban overpasses, underground garage ramps, and gentle rural slopes.
Frame Design and Carrying: Seat Height Adjustment and Tire Specs
The seat height adjustment range of 78–100 cm, combined with the recommended height of 155–198 cm, allows one bike to cover a broad user group. The 20×4.0 inch pneumatic tires balance rolling resistance on paved roads and cushioning on unpaved surfaces, with the tire width providing extra stability. The overall dimensions of 173×70×110 cm and package dimensions of 144×32×78 cm facilitate logistics transport and storage. The maximum load of 150 kg covers rider weight and carried items, suitable for commuting with cargo and short shopping trips.
Display and Protection: LCD Screen and IPX5 Waterproofing
The LCD display centrally presents speed, battery, and assist status, and the cadence sensor adjusts motor output according to pedaling rhythm, making the riding experience an extension of a traditional bicycle. The IPX5 waterproof rating handles daily rain and car-wash splashes; prolonged immersion or direct high-pressure washing is not recommended. The combination of aluminum alloy frame and hydraulic disc brakes provides relatively balanced handling feedback at a curb weight of 33.2 kg. The 40mm front suspension travel and 20×4.0 inch pneumatic tires together form a road-filtering system, suitable for urban paved roads and light gravel roads.
