The 2021 i:SY DrivE S8 ZR RT in grey is a versatile e-bike that impresses with its well-thought-out features and robust construction. Priced at 3,499 euros, it offers a combination of quality and functionality that is suitable for both daily city commuting and longer trips. The frame is made of aluminium and is specifically designed as an I:SY Bosch Belt model, which not only contributes to its stability but also allows for a maximum load capacity of up to 140 kg.
The bike’s braking system comprises SHIMANO “MT-M402” brakes and brake levers, complemented by a 180 mm SHIMANO “RT54” front brake disc and a 160 mm SHIMANO “RTC60” rear brake disc. These components ensure reliable braking performance under a wide range of conditions. Gear changes are handled by the SHIMANO “Nexus” 8-speed system, which, together with the GATES “Centertrack CDX” belt drive, ensures quiet and low-maintenance operation.
Comfort and safety are ensured by the aluminium disc fork in combination with SCHWALBE “Super Moto-X” tyres (62-406) on MACH 1 “Kargo Disc” rims. The lighting system consists of the B&M “Lumotec IQ Eyc” front light with 50 lux and a B&M rear light, which ensure sufficient visibility in the dark. The ERGOTEC “Ladytown” handlebars and HERRMANS “Line” grips offer comfortable handling, whilst the SELLE ROYAL “Nuvola 5060” saddle and the CONTEC Patent “Brut” seatpost provide additional comfort.
The drive system is powered by a BOSCH “Active Plus” mid-drive motor with a rated continuous power output of 250 W at 36 V and a BOSCH lithium-ion battery with a capacity of 500 Wh. The BOSCH “Intuvia” display with 4 levels and remote control offers intuitive operation and includes a pedal-assist function. Other practical features include the RACKTIME “Stand it Shine Evo i:SY” luggage rack with integrated light, CURANA “C-Lite” mudguards, an M-TEC “Aluminium Belt” chain guard and a PLETSCHER “Comp 18 Flex” kickstand.
Overall, the i:SY DrivE S8 ZR RT is a well-designed e-bike, equipped with high-quality components to deliver both comfort and performance. It is a solid choice for anyone looking for a reliable and versatile means of transport.
