About RES U400 Men

The RES U400 is a user-friendly, stylish, light-weight e-bike that is made for lightning-fast trips in and around the city. Traffic jams or parking stress are a thing of the past: with this city e-bike, you will cycle comfortably and carefree along city streets and quiet village roads. The battery of the RES U400 has a capacity of 360Wh, enough for hours of cycling fun with a push in the back.

This e-bike is perfect for commuting to work, a quick errand in town or a tour through the countryside. On the handy carrier you can easily take your laptop bag, daily shopping or everything you need for a fun day out. Furthermore, the light weight and the handy walking function make the RES U400 easy to take with you on public transport or upstairs in an apartment building. This bike is city-proof!

The RES U400 is powered by a rear wheel motor. The motor is just as powerful as a mid-motor system, but has a big advantage: it is lighter in weight. The integrated battery also contributes to the light weight of the bicycle.

The hydraulic disc brakes, LED lights on the front and back, and reflective stickers provide extra safety on the bike. The U400 is not only stylish, but also comfortable. The wide tyres provide good cushioning. With the geometry of the U400, you are assured of maximum comfort while riding.
