The "Hydric Dry 8" model from KAYZA, launched in 2022, is a versatile e-bike fitted with high-quality components and suitable for a wide range of uses. Priced at 3549 EUR, the bike offers good value for money, particularly thanks to the use of advanced technologies and reliable components.
At the heart of the Hydric Dry 8 is the BOSCH Gen.4 “Performance CX” mid-drive motor, which delivers powerful assistance with an output of 250 W at 36 V. The motor is powered by a BOSCH “Powertube 625” battery, which, with its capacity of 625 Wh, enables an impressive range. Control is via the BOSCH “Purion” display, which offers four assistance levels as well as a push assist function.
To ensure safe deceleration, the bike is fitted with SHIMANO “MT-4023” brakes, operated via SHIMANO “MT-4101” brake levers. The brake discs measure 203 mm at the front and 180 mm at the rear, ensuring effective braking performance. Gear changes are handled by the SRAM “RD-SX-1-A1” system, combined with the SRAM “SX EAGLE” trigger shifter, enabling precise and reliable gear changes.
The ROCK SHOX “Judy TK” fork, with 120 mm of travel and Boost technology, ensures a comfortable ride even on uneven terrain. The Hydric Dry 8 is lit by the CONTEC “DLUX 50 E+” front light, delivering 50 lux, and the CONTEC “CTL 335 E” rear light, which ensures good visibility.
Further features include the robust KAYZA “X17” hollow-section rims, fitted with SCHWALBE “Smart Sam” tyres in size 57-584 to provide good grip both on the road and off-road. The SELLE ROYAL “Vivo” saddle and the PROMAX “SP-2016” seatpost, with a diameter of 30.9 mm, offer comfort for longer rides.
The bike also features practical accessories such as the ATRAN “Tour Sport” luggage rack, SKS “A65 R” plastic mudguards and the URSUS “Modi Rear 40” kickstand. The aluminium HL “MTB-320” handlebars are 740 mm wide and are complemented by the HL “TDS-C507” stem, which is 70 mm long, ensuring a comfortable riding position.
Overall, the KAYZA Hydric Dry 8 impresses with its well-thought-out specification and the use of high-quality components, which are suitable for both everyday use and more demanding tours.
