A new sense of lightness

The E-Comuna 7.4.1 is a rather special e-touring bike. It is a powerful, reliable companion. In designing its frame, the focus was on low weight, durability and a functional, timeless design. The compact Bosch Performance Line SX drive unit, with a maximum torque of 60 Nm, keeps the e-bike’s weight incredibly low at just 21 kilograms, ensuring maximum riding enjoyment. The Bosch CompactTube 400 battery is housed in the down tube and is removable – for hassle-free charging at home and on the go. The integrated cable routing through the headset ensures a contemporary, clean design, whilst the comfortable geometry with an upright riding position allows for long rides and provides excellent visibility in city traffic. Available in the subtle Black Mercury colour as a high-tube, low-tube and, new, as a particularly comfortable Forma frame variant.
