The “DrivE XXL N3.8 ZR green” model from the i:SY brand, released in 2021, is a high-quality e-bike characterised by its robust construction and a wide range of well-thought-out features. The frame is made of aluminium and is designed to support a maximum load of up to 180 kg, which is a testament to its exceptional stability and durability. Power is provided by a BOSCH mid-drive motor from the “Performance” series with a rated continuous power output of 250 watts, powered by a BOSCH lithium-ion battery with a capacity of 500 Wh. This ensures reliable assistance across a range of riding conditions.
Safety is ensured by SHIMANO “MT-M402” disc brakes, fitted with a 180 mm brake disc at the front and a 160 mm brake disc at the rear. The gear system consists of a continuously variable ENVIOLO “TR” gear lever, which allows for comfortable adjustment of riding speed. The aluminium fork and the MACH 1 “Kargo Disc” rims contribute to stability and riding comfort. The tyres are SCHWALBE “Super Moto-X” tyres, fitted in size 62-406 at both the front and rear.
The lighting system comprises a B&M “Lumotec IQ Eyc” front light with 50 lux and a B&M rear light, ensuring good visibility in traffic. The ERGOTEC “Ladytown” handlebars and HERRMANS “Line” grips offer ergonomic handling. The stem is an ERGOTEC “Piranha 650B” with a SPEEDLIFTER “T22”, which allows for 220 mm of extension.
Other practical features include the UNION “SP-153” folding pedal, a STRONGLIGHT “Magan” crankset with GATES “CDX, 55T” chainring, and the GATES “Centertrack CDX” belt drive with a 22-tooth sprocket. The SELLE ROYAL “Nuvola 5060” saddle and the ERGOTEC “Skalar” seatpost offer additional comfort. The model features CURANA “C-Lite” composite 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 and an i:SY “Fix” front luggage rack with KLICKfix.
The BOSCH “Intuvia” display with 4 levels, remote control and push assist rounds off the equipment package. The price for the i:SY DrivE XXL N3.8 ZR in green is 3999 EUR, which seems reasonable given the extensive and high-quality specification.
