The “DrivE N3.8 ZR grey” model from the i:SY brand, released in 2021, offers a wide range of technical features and high-quality specifications. The frame is made from an I:SY Bosch Belt aluminium alloy, making the bike not only robust but also relatively light. The maximum load capacity is 140 kg, which is a considerable load capacity for an e-bike of this type.
The SHIMANO “MT-M402” system, renowned for its reliability and efficiency, has been chosen for the brakes and brake levers. The front brake discs are SHIMANO “RT54” (180 mm) and the rear SHIMANO “RT56” (160 mm), ensuring good braking performance. The ENVIOLO “TR” gear lever in grey allows for stepless adjustment of the gear ratio, which enhances riding comfort.
The aluminium fork is designed for disc brakes, and lighting is provided by the B&M “Lumotec IQ Eyc” front light (50 lux) and a B&M rear light. The UNION “SP-153” folding pedals contribute to the bike’s flexibility and storage convenience.
Power is transmitted via a GATES “Centertrack CDX” belt, which is combined with a STRONGLIGHT “Magan” crankset and a GATES “CDX” sprocket with 22 teeth. The handlebars are ERGOTEC “Ladytown” with a diameter of 31.8 mm, complemented by HERRMANS “Line” grips and an ERGOTEC “Piranha 650B” stem with a SPEEDLIFTER “T17” for adjustable height.
The rims are MACH 1 “Kargo Disc”, and the tyres are SCHWALBE “Super Moto-X”, ensuring a stable ride and good grip. The front hub is a SHIMANO “Deore HB-M6000” QR and the rear hub is an ENVIOLO “TR” continuously variable hub, which contributes to smooth power transmission.
The SELLE ROYAL “Nuvola 5060” saddle offers comfort on long rides, supported by a CONTEC patented aluminium seatpost. CURANA “C-Lite” mudguards and an M-TEC aluminium chain guard provide protection against dirt and wet conditions. The PLETSCHER “Comp 18 Flex” kickstand ensures the bike stands securely, whilst the RACKTIME “Stand it Shine Evo i:SY” luggage rack with integrated light provides additional storage space.
Power is provided by a BOSCH “Performance” mid-drive motor with a rated continuous power output of 250 W and a voltage of 36 V. The battery is a BOSCH lithium-ion model with a capacity of 500 Wh, which enables a reasonable range. The BOSCH “Intuvia” display offers four assistance levels and a push-assist function, making the e-bike easy to operate.
The price for the i:SY DrivE N3.8 ZR in grey is 3,699 EUR, which represents an attractive offer given its high-quality specifications and technical features.
