75Nm Torque Sensor for Smoother Pedal Assistance

The RCB G19 is equipped with a responsive torque sensor system and 75Nm torque output. The torque sensor detects how hard you pedal and adjusts motor support more naturally, giving riders smoother acceleration, better climbing support and improved riding efficiency.

Whether you are starting from a stop, riding uphill or cruising on flat roads, the RCB G19 provides stable and controlled assistance for a more natural riding experience.

5 Pedal Assist Modes for Different Riding Conditions

The RCB G19 offers 5 adjustable pedal assist levels, allowing riders to choose the right amount of support for different riding situations.

Lower assist levels are suitable for daily commuting, relaxed city riding and better battery efficiency. Higher assist levels provide stronger support for hills, longer distances, gravel paths and heavier riding conditions.

All pedal assist modes are limited to a maximum assisted speed of 25 km/h.

48V 22.5Ah Battery with Up to 130KM Range

Powered by a large 48V 22.5Ah lithium battery with 1080Wh capacity, the RCB G19 can reach up to 130 km on a single full charge under suitable riding conditions.

This long-range battery makes the bike suitable for daily commuting, weekend rides, longer outdoor routes and riders who want fewer charging stops.

Actual range may vary depending on rider weight, road conditions, assist level, terrain, temperature, wind, tire pressure and riding habits.

250W EU-Compliant Motor for Legal Daily Riding

The RCB G19 uses a 250W motor designed for European e-bike standards, with pedal assistance limited to 25 km/h.

This makes the RCB G19 suitable for riders looking for a road-legal electric bike for everyday use in many European markets where 250W pedelec regulations apply.

The motor delivers stable and consistent power for commuting, gentle hill climbing and mixed urban or outdoor surfaces.

Smart APP Control and Color LED Display

The RCB G19 includes a smart riding system that helps riders monitor and control the e-bike more easily.

Through the mobile APP, riders can check vehicle information and access smart control functions. The color LED display clearly shows key riding data, including current speed, battery level, assist mode, lighting status, riding information and error codes.

This makes the bike easier to manage during daily commuting, long-distance rides and outdoor use.

NFC Unlock and 4-Digit Password Lock

For better daily security, the RCB G19 supports dual anti-theft unlocking.

Riders can unlock the e-bike using NFC card access or a secure 4-digit dashboard password. This adds an extra layer of protection when parking the bike during commuting, shopping, outdoor stops or short breaks.

20-Inch Fat Tires for City Roads and Light Off-Road Riding

The RCB G19 features 20-inch wide fat tires that provide better grip, stability and comfort across different surfaces.

The fat tire design helps improve control on city streets, gravel paths, bumpy roads, uneven ground and light off-road routes. Combined with a shock-absorbing ergonomic seat, the bike helps reduce vibration and provides a more comfortable ride over longer distances.
