The 2022 i:SY E5 ZR RT is a compact and versatile e-bike that stands out for its well-thought-out features and robust construction. The frame is an original i:SY compact frame with a height of 47 cm and offers a unisex fit suitable for a wide range of riders. The maximum rider weight is 140 kg, whilst the bike itself weighs 23 kg.
The braking system consists of a SHIMANO BR-MT 420 hydraulic 4-piston disc brake at the front and a SHIMANO BR-MT 410 hydraulic disc brake at the rear, which, together with the SHIMANO SM-RT54 brake discs (180 mm at the front, 160 mm at the rear) ensure reliable braking performance. The SHIMANO Nexus 5-speed gear system with coaster brake is operated via a SHIMANO Nexus Revo shifter and offers simple and intuitive operation.
The rigid fork from i:SY ensures a direct riding feel, whilst the drive is provided by a GATES CDX Centretrack toothed belt, which is renowned for its durability and low maintenance. The BOSCH Performance Line motor, with an output of 250 W and a voltage of 36 V, is powered by a BOSCH PowerPack 500 battery with a capacity of 500 Wh, providing sufficient range for extended rides. The BOSCH Intuvia display allows for easy control and monitoring of the motor assistance.
For lighting, the e-bike is fitted with a FUXON FF-100HB front light, which ensures good visibility with 100 lux and a high-beam function. The COMUS COB-LED rear light is integrated into the luggage rack. The i:SY Carrier luggage rack with Monkey Load Adapter offers practical transport options. The SKS Bluemels mudguards and the Horn Catena chain guard protect against dirt and moisture.
