The 2023 KAYZA Hydric Dry 5.7 hardtail is a versatile e-bike that stands out for its robust construction and high-quality components. The frame is made from 6061 aluminium and is semi-integrated to accommodate the powerful fourth-generation Bosch mid-drive motor, the ‘Performance CX’. This motor delivers 250 W of power and operates on a 36 V system powered by the Bosch “PowerPack 545” battery. With a capacity of 545 Wh and a BMS (battery management system), the battery ensures a reliable power supply and supports the rider in a variety of riding conditions.
The bike features a 9-speed Shimano “Acera” derailleur, controlled via the Shimano “Alivio” shift lever. The brakes are ALHONGA ‘HT472’ models and, with their 180 mm brake discs at both the front and rear, provide strong braking power. The RST “Blaze-ML-27.5” fork, with 120 mm of travel, ensures good suspension on uneven terrain.
Lighting is provided by the CONTEC “DLUX 50 E+” front light and the CONTEC “CTL 335 E” rear light, which ensure safety on the road. The KAYZA Hydric Dry 5.7 is fitted with CONTI “Contact Urban” tyres mounted on KAYZA “X18” hollow-section rims, ensuring a stable and comfortable ride.
The handlebars are CONTEC “Moab” with a diameter of 31.6 mm and a width of 740 mm, whilst the stem is also from CONTEC and has a length of 70 mm. The SR “Vivo Sport Ergo” saddle offers comfort even on longer rides, and the seatpost is a CONTEC “Pillar” with a diameter of 31.6 mm and a length of 400 mm.
Additional features such as the ATRAN “Tour Sport” luggage rack, SKS “A65 R” plastic mudguards and the URSUS “Mooi R90” kickstand round off the overall package. The KAYZA Hydric Dry 5.7 hardtail has a maximum load capacity of 130 kg and is available for 3399 EUR. With its well-thought-out technical details, this model is aimed at discerning riders who value quality and reliability.
