The i:SY XXL E5 ZR RT COMFORT with a coaster brake stands out with its 5-speed gear hub by SHIMANO which was specially developed for e-bikes. It also comes with a clean belt drive. The COMFORT version features a suspension seat post from BySchulz, a handlebar which is stronger bent, a shorter stem for an even more upright seating position along with an even larger saddle for more riding comfort. The i:SY XXL was primarily designed for taller riders - up to 210 cm. All parameters were adopted accordingly and thus withhold a heavier load. The total permitted weight is 180 kg. The new BOSCH Smart System lets you dive into the digital e-Bike world and connects display, control unit and motor with your smartphone via ebike Flow App. Like all of our i:SY models the i:SY XXL E5 ZR RT COMFORT comes with cross-series fittings. The Speedlifter Twist enables you to not only change the height of the handlebar but also turn it horizontally by 90 degrees, completely tool-free. In adition to that the pedals can be folded with one click - a feature that comes with all of our i:SY models.
