The “DrivE S8 ZR RT red” model from the i:SY brand, released in 2021, is a versatile e-bike that stands out for its high-quality features and well-thought-out design. The frame is made of aluminium and has been specially designed as an I:SY Bosch Belt model, ensuring a durable and stable construction. The maximum permissible weight is 140 kg, providing ample capacity for both rider and luggage.
Braking performance is provided by SHIMANO “MT-M402” brakes and brake levers, fitted with a 180 mm SHIMANO “RT54” brake disc at the front and a 160 mm SHIMANO “RTC60” brake disc at the rear. Gear changes are handled by the SHIMANO “Nexus” 8-speed hub gear system, which, together with the SHIMANO “Nexus” gear lever, ensures smooth gear changes.
The aluminium disc fork and the BOSCH “Active Plus” mid-drive motor, with a rated continuous power output of 250 W, ensure a comfortable riding experience. The motor is powered by a BOSCH lithium-ion battery with a capacity of 500 Wh, which provides sufficient power for longer rides. The BOSCH “Intuvia” display allows for easy control of the four assistance levels and features a push-assist function.
The e-bike is fitted with a GATES “Centertrack CDX” belt drive, combined with a STRONGLIGHT “Magan” crankset and a GATES “CDX” 22-tooth sprocket. These components contribute to quiet and low-maintenance operation. The ERGOTEC “Ladytown” handlebars and the ERGOTEC “Piranha 650B” stem with SPEEDLIFTER ensure a comfortable riding position.
For lighting, the model is fitted with a B&M “Lumotec IQ Eyc” front light with 50 lux and a B&M rear light. The UNION “SP-153” folding pedals offer additional flexibility, whilst the SELLE ROYAL “Nuvola 5060” saddle and the CONTEC Patent seatpost ensure comfort. The MACH 1 “Kargo Disc” rims and the SCHWALBE “Super Moto-X” tyres ensure stability and grip on a variety of surfaces.
Additional features such as CURANA “C-Lite” mudguards, an M-TEC aluminium belt chain guard, a PLETSCHER “Comp 18 Flex” kickstand and a RACKTIME “Stand it Shine Evo i:SY” luggage rack with integrated light round off the overall package. The price for the i:SY DrivE S8 ZR RT in red is 3499 EUR, which offers good value for money given the high-quality equipment and technical features.
