Enjoyable Riding Experience With R8S

Designed For Comfortable Riding Experience

  • Front Suspension

    The fork spring suspension has an effective damping travel of approximately 10cm, which effectively reduces the vibration caused by uneven surfaces and allows you to control the ebike's direction of travel even when riding on bad roads as if it were flat.

  • Wider Saddle

    Obviously, the R8S is fitted with a huge saddle, which is ergonomically designed with three-dimensional foam plasticity and a surface that fits better to the line of the body's hips. There are two sets of springs under the saddle for shock absorption, which makes for a comfortable ride and is ideal for longer rides.

  • Shimano 8-Speed Transmission

    To give you more options in riding mode for different road conditions (e.g. uphill, gentle, paved, downhill) the R8 uses a 1:8 freewheels system which shifts smoothly and consistently, saving you energy on your ride and allowing you to ride easier and further.

  • Responsive Brakes

    The braking system uses a hydraulic oil brake system that is maintenance-free and the 160MM discs feature fast heat dissipation and consistent performance. The braking system also automatically cuts off power to the motor when you brake, which makes it safer when you brake in an emergency.

  • Ebike lighting

    Features a newly designed large LED headlight with integrated electronic horn and a lumen distance of approx. 10M and a separately powered LED tail light (3 flashing modes) for the rear tail light. The front light + tail light make you safer riding at night.

  • Long battery life

    48V20AH removable high-capacity lithium battery, light in mass but large in capacity, with a service life of about 1200 cycles of charging and discharging or 11-12 months. It can be fully charged in 5-6 hours per charge and has a range of 75-80KM in boost mode. the detachable design gives you more flexibility in charging.

  • Colourful Instrumentation

    The waterproof meter with colour screen and cool management page allows you to monitor the status of the ebike at any time, such as speed, mileage, battery level, voltage, fault codes etc.

  • Easy to Ride

    With R8S‘s 80N-M high-speed brushless motor and rear-mounted design, it gives you great auxiliary power while you ride. Even uphill conditions can be easily overcome with the help of the booster mode.

Pedal Assist System(PAS)

What makes e-bikes special is their Pedal Assist System (PAS). People think that e-bikes cannot be used for exercise, however this is not the case. In fact, PAS allows the cyclist to pedal in a more comfortable and efficient way.
Cyclists can ride the bike entirely on pedals, using only the motor, or a combination of both (PAS). In PAS mode, the bike's computer detects pedalling and activates the motor to assist and power the ride.
Of course, the type of sensors and supported power assist modes may vary from ebike assist to ebike assist. The riding experience will also be slightly different.

The riding modes supported by R8S are:

  • Throttle mode
  • Pedal assist mode(PAS)
  • Riding mode

The type of sensor used is: Cadence Sensor
