The "Tanana Dry 8" model from the KAYZA brand, released in 2022, is an e-bike positioned in the upper mid-range with a price of 3249 EUR. It is fitted with high-quality components designed for both everyday use and longer rides. At the heart of the bike is the fourth-generation BOSCH “Performance CX” mid-drive motor, which operates at 250 watts and 36 volts. The motor is powered by a BOSCH “Powertube 625” lithium-ion battery with a capacity of 625 Wh, which enables a considerable range. The system is controlled via the BOSCH “Intuvia” display, which offers four assistance levels and features an integrated push assist.
Safety and control are ensured by the SHIMANO “MT-200” brakes with matching brake levers and a 180mm front brake disc. The gear system, featuring the SHIMANO “Deore RD-M5120” rear derailleur and the “Deore SL-M4100” shifter, is also high-quality and reliable. The SUNTOUR “SF15-NEX-E25-DS-LO” fork is adjustable and features a lockout, ensuring a comfortable ride on various surfaces.
The lighting comprises a CONTEC “DLUX 50 E+” front light and a HERRMANS “H-Trace” rear light, which ensure good visibility. The MIRANDA Gen.4 crankset and the SHIMANO “CS-M4100” cassette with 11–46 teeth contribute to the efficiency of the drivetrain, which is powered by a KMC “e10S” chain.
The bike features HL “MTB-320” aluminium handlebars, 680 mm wide, and CONTEC “Tour Wing Eco” grips for a comfortable grip. The stem is a PROMAX “MA-504” with a length of 90 mm. The KAYZA “X6” hollow-wall rims, combined with SCHWALBE “Energizer Active Plus” tyres in size 50-622 with reflective strips, offer stability and puncture protection. The hubs are by SHIMANO: the “HB-M4050BL” QR at the front and the “FH-M4050” QR at the rear, complemented by black stainless steel spokes.
The SELLE ROYAL “Essenza Plus” saddle, together with the PROMAX “SP-2016” seatpost, ensures comfort on long journeys. Practical features such as the SKS “A56” plastic mudguards, the adjustable URSUS “Mooi” aluminium kickstand and the ATRAN “Tour Sport” luggage rack round off the specification. The Bosch 2 Ah charger ensures the battery recharges quickly, so the e-bike is back up and running in no time. Overall, the KAYZA Tanana Dry 8 offers a balanced combination of performance, comfort and practicality, making it an attractive choice for e-bike enthusiasts.
