The 2023 KAYZA Hydric 3.7 is a versatile e-bike that stands out for its robust construction and high-quality features. Priced at 2699 EUR, it offers good value for money for anyone looking for a reliable and high-performance bike. The frame is made from KAYZA Bosch 6061 aluminium, ensuring durability and stability. The model is fitted with ALHONGA hydraulic disc brakes, fitted to both the front and rear. The brake levers are also from ALHONGA and, with their 2-finger design, offer precise control.
Gear changes are handled by the 9-speed SHIMANO “Cues” system, which enables smooth and efficient gear changes. The RST “Blaze-ML-27.5” fork, with 120 mm of travel and a tapered design, ensures a comfortable ride even on uneven terrain. The black VP “VPE-506” pedals provide a stable platform for the rider. The bottom bracket is supplied by Bosch, which, in combination with the Bosch motor and a battery capacity of 500 Wh, ensures powerful assistance.
The CONTEC “Moab” handlebars, with a diameter of 31.8 mm and a width of 740 mm, together with the CONTEC “MTB Straight long” grips, provide an ergonomic and comfortable riding position. The stem, also from CONTEC, measures 70 mm and complements the handlebar design perfectly. The KAYZA “X18” hollow-wall rims are designed for use with disc brakes and fitted with MAXXIS “Rekon” tyres in size 27.5x2.4, which provide excellent grip.
The black Niro spokes connect the FORMULA hubs, with the front “DC-20” hub and the rear “EHL-148S” hub each featuring 32 holes. The SR “Vivo Sport Ergo” saddle offers comfort even on longer rides, whilst the CONTEC “Pillar” seatpost, with a diameter of 31.6 mm and a length of 400 mm, provides additional adjustment options.
A transparent chain guard from BLASE protects against dirt and damage, whilst the CONTEC “Powerlock” battery lock ensures security. Overall, the KAYZA Hydric 3.7 is a well-designed e-bike that is suitable for both everyday use and sporty rides.
