Low maintenance for everyday use Infinite automatic ENVIOLO hub gearing and low-maintenance GATES® belt drive Maximum range for long rides with the PowerTube 750 Powerful Bosch Performance Line CX (Smart System) motor Featuring an aluminum frame with excellent stability and safety ratings, the QUADRIGA frame lays the foundation for a high-quality, comfortable e-bike. The powerful Bosch Performance Line CX (Smart System) motor delivers strong propulsion, whether on steep hills or uneven terrain. With a maximum torque of 85 Nm, it allows for vigorous acceleration even at low pedaling frequencies, which is useful when navigating around obstacles. The integrated 750 Wh battery in the sleek down tube enables impressive ranges. Even in the compact Wave frame, the large battery fits comfortably and can be easily removed and inserted from the side. The touchless Kiox 300 color display, controlled via the LED Remote, allows for easy access to data such as distance, ride duration, range, and riding mode. The infinite gear shifting system from ENVIOLO enables smooth transitions, even under heavy loads, while the robust, rust-free GATES® belt drive operates extremely quietly. Both are nearly maintenance-free components, as wear and tear are minimized. Comfort is ensured by the suspension fork and adjustable dropper seat post; with disc brakes and an extremely bright 100 Lux headlight, the PRO BELT AUTOMATIC is well-equipped for safety.
