The Mivice X700 mid-drive motor delivers 100 Nm of torque for powerful and responsive assistance. The integrated torque sensor detects your pedaling force in real time and automatically adjusts motor support. Whether starting, climbing hills, or carrying luggage, the Quartz Pro provides smooth and controlled assistance.
The 48V 644Wh battery offers a range of up to 161 km, making the Quartz Pro ideal for daily commuting, longer cycling tours, and relaxed weekend rides. The removable battery can be easily taken out and conveniently charged away from the bike.
The 6061 aluminium step-through frame makes mounting and dismounting particularly easy. With a 47 cm frame height and an upright riding position, the Quartz Pro combines comfortable handling, stable control, and a modern design – ideal for urban traffic and frequent stops.
The Shimano CUES 9-speed drivetrain offers precise shifting and a versatile gear range for flat roads and climbs. Tektro HD-T275 hydraulic disc brakes with 180 mm front and 160 mm rear rotors provide reliable braking performance and precise control.
The TFT colour display with Bluetooth connects to the DERUIZ E-Bike App and shows riding data, battery level, range, and system settings. Schwalbe Big Apple 28 × 2.0 tyres with puncture protection ensure comfortable riding, while the 25 kg rear rack, 120 Lux StVZO-certified lighting, mudguards, and adjustable kickstand make the Quartz Pro well equipped for everyday use.
