Chic and swift – two perfect attributes for a modern commuter bike. On the glossy black Zouma Supreme + with red anodized accents on handlebar , seat clamp and rear derailleur, the driver simply makes a good impression – and it feels good. Because the noble Ross spoils thanks to its suspension fork , ergonomic handles and a very relaxed sitting position with rich comfort.

At the same time, it shines through direct obedience: steering commands sets the Zouma to quickly and accurately. And thanks to the Flüstermotors the rear it roars his aim against almost noiselessly. A too pronounced forward momentum shows the diamond bike but not necessarily. The test driver missing a bit the “bang” that a S-pedelec otherwise may well evince.

Simultaneously, the bike, the rear is the range check. On the bike ride, the battery lasted for the full support of just over 38 kilometers. Hillside was over already after 22 kilometers. As might be needed in the office so reloading. However, the rear-wheel drive also offers a recuperation. So the battery can be fed about on sloping passages by braking energy.

The big advantage: Unlike many other Pedelecs and S-Pedelecs can the Zouma drive very neatly without switched in engine power through the streets. This is partly due to the relatively low weight of only 23.7 kilograms, the other at the well-graded, high quality Shimano XT derailleur with 27 gears.

Ever convinced the high-quality equipment, such as hydraulic Magura disk brakes, Supernova LED headlamps or the Suntour suspension fork with lock-lever on the handlebar. Also the cycling computer knows how to please: The display is easy to read, and use the remote control on the handlebar of the driver shifts quickly and intuitively through the modes.
