The “DrivE XXL N3.8 ZR blue” model from the i:SY brand, released in 2021, is a high-quality e-bike which, at a price of 3,999 EUR, is positioned in the upper mid-range. The bike’s frame is made of aluminium and was specially developed for the Bosch XXL system, which ensures high stability and a maximum permissible weight of up to 180 kg. This model is fitted with powerful SHIMANO “MT-M402” brakes and brake levers, combined with a 180 mm front brake disc and a 160 mm rear brake disc to ensure reliable braking performance.
The bike is driven by a GATES “Centertrack CDX” belt, which, in combination with a STRONGLIGHT “Magan” crankset and a GATES “CDX” sprocket with 22 teeth, ensures a powerful and low-maintenance drivetrain. The ENVIOLO “TR” gear lever in grey allows for continuous adjustment of the gear ratio. The aluminium fork is designed for use with disc brakes and contributes to the bike’s overall stability.
Optimal lighting is provided by the B&M “Lumotec IQ Eyc” front light with 50 lux and the B&M rear light, both of which are integrated into the system. The UNION “SP-153” folding pedals offer flexibility and comfort whilst riding. The BOSCH “Performance” mid-drive motor, with a rated continuous power output of 250 W and a voltage of 36 V, combined with the BOSCH lithium-ion battery with a capacity of 500 Wh, ensures powerful assistance on every ride. The BOSCH “Intuvia” display offers four assistance levels as well as a push assist and is operated via a remote control.
The ERGOTEC “Ladytown” handlebars and HERRMANS “Line” grips offer comfortable ergonomics, whilst the ERGOTEC “Piranha 650B” stem with SPEEDLIFTER “T22” ensures flexibility in handlebar height. The MACH 1 “Kargo Disc” rims and SCHWALBE “Super Moto-X” tyres offer stability and comfort on a variety of surfaces. The SHIMANO “Deore HB-M6000” front hub and the continuously variable ENVIOLO “TR” rear hub round off the high-quality specification.
The SELLE ROYAL “Nuvola 5060” saddle, mounted on an ERGOTEC patented “Skalar” seatpost, ensures comfort on long journeys. The CURANA “C-Lite” mudguards, made from composite material, protect against dirt and water, whilst the M-TEC “Aluminium Belt” chain guard keeps the drivetrain clean. Additional functionality is provided by the PLETSCHER “Comp 18 Flex” kickstand and the RACKTIME “Stand it Shine Evo i:SY” luggage rack with integrated light and the i:SY “Fix” front luggage rack with KLICKfix system, both of which provide transport options. This e-bike combines functionality, comfort and performance in an attractive design, ideal for everyday use or longer rides.
