The "Hydric Dry 7.9 Hardtail" model from KAYZA, launched in 2023, is a versatile e-bike characterised by its robust construction and high-quality components. The frame is made from 6061 aluminium and is designed as a hardtail with integrated Bosch technology, ensuring stability and durability. With a maximum load capacity of 130 kg, the bike offers sufficient load-bearing capacity for the rider and additional luggage.
The bike is fitted with ALHONGA “HT472” brakes, which are combined with 180 mm brake discs at both the front and rear to ensure reliable braking performance. The 10-speed SHIMANO “Deore” derailleur enables precise and easy gear changes, whilst the SHIMANO shift lever makes operation straightforward. The SUNTOUR “SF19-XCR32-Boost-AIR-LOR-DS-15QLC32-110-29” fork, with 120 mm of travel, ensures a comfortable ride even on uneven terrain.
For lighting, the bike is fitted with the CONTEC “DLUX 50 E+” front light and the CONTEC “CTL 335 E” rear light, which ensure sufficient visibility in the dark. The drive is powered by a BOSCH Gen.4 “Performance CX” mid-drive motor with 250 W of power, whilst the BOSCH “PowerPack 725” battery, with a capacity of 725 Wh, ensures long-lasting rides. The BOSCH “Intuvia 100” display also offers a pedal assist function and displays key information whilst riding.
The KAYZA “X18” hollow-chamber disc rim set is fitted with CONTI “Contact Urban” tyres, which offer additional safety thanks to their reflective strips. The rims are combined with FORMULA hubs, which ensure stable wheel guidance. The ergonomic SR “Vivo Sport Ergo” saddle and the CONTEC “Pillar” seatpost offer comfort even on longer journeys.
Further features such as the ATRAN “Tour Sport” luggage rack, SKS “A65 R” mudguards and the CONTEC “Powerlock” battery lock round off the overall package. Priced at 3899 EUR, the Hydric Dry 7.9 hardtail from KAYZA offers excellent value for money for anyone looking for a reliable and high-performance e-bike.
