The “DrivE S8 RT white” model from the i:SY brand, released in 2021, is a high-quality e-bike available for 2,899 EUR. The frame is made of aluminium and, combined with the aluminium fork, provides a sturdy yet lightweight base for the bike. With a maximum load capacity of 140 kg, the bike is robust enough to safely carry both the rider and any additional luggage.
The braking system comprises MAGURA “HS22” brakes and matching brake levers, ensuring reliable braking performance. The SHIMANO “Nexus” 8-speed gear system allows for easy and precise gear changes, aided by the SHIMANO gear lever. Power is transmitted via the KMC “E01 EPT” chain, whilst the STRONGLIGHT “Magan” crankset with 44 teeth and the SHIMANO 16-tooth sprocket ensure efficient propulsion.
For lighting, the bike is fitted with a B&M “Lumotec IQ Eyc” front light with 50 lux and a B&M rear light, which ensure good visibility in traffic. The UNION “SP-153” folding pedals contribute to the bike’s flexibility and portability. The handlebars are an ERGOTEC “Ladytown” model with a diameter of 31.8 mm, complemented by HERRMANS “Line” grips for comfortable handling. The ERGOTEC “Piranha 650B” stem with SPEEDLIFTER technology allows for individual adjustment of the handlebar height.
The bike rides on MACH 1 “Kargo” rims and is fitted with SCHWALBE “Big Ben Plus” tyres, mounted in size 55-406 at both the front and rear. The front hub is a SHIMANO “Deore HB-T610” and the rear hub is a SHIMANO “Nexus” 8-speed RBN, which, together with the Niro spokes, results in a sturdy and reliable wheel construction.
The SELLE ROYAL “Nuvola 5060” saddle offers comfort on longer rides, supported by a CONTEC patented aluminium seatpost. CURANA “C-Lite” mudguards protect against dirt and wet conditions, whilst the HEBIE “Chainglider” chain guard keeps the chain clean. A PLETSCHER “Comp 18 Flex” kickstand ensures the bike stands securely, and the RACKTIME “Stand it Shine Evo i:SY” luggage rack with integrated light provides additional storage space.
Power is provided by a BOSCH “Active” mid-drive motor with a rated continuous power output of 250 W at 36 V. The accompanying BOSCH lithium-ion battery has a capacity of 400 Wh (11.11 Ah) and is controlled via the BOSCH “Intuvia” display, which offers four assistance levels as well as a push assist. Overall, the i:SY DrivE S8 RT in white offers a well-thought-out combination of comfort, performance and functionality.
