The Roadster's favourite activity is chasing asphalt. And it does it so quickly that those envious glances can barely keep up. Out of the city and into the countryside with all the riding qualities and classical aesthetics of a racing bike. Here, the Roadster’s smooth-running Schwalbe tires can handle even country lanes and farm tracks. Back on the avenues and boulevards, you’ll enjoy your and the Roadster's sporty style with true panache and get every last km/h out of it.

The high frame stability and optimised weight distribution ensure superlative riding stability at high speeds. An agile ride and a clear view of city traffic are guaranteed thanks to the short stem and straight handlebars. You’ll see yourself reflected in the city's shop windows as you glide past. And you’ll smile because you’re now seeing for yourself what we mean by E-sthetics.

Features: A racing bike classic is reborn. Bristling with beautiful design features and made for fast riding and lots of riding pleasure, the Bosch Performance motor and Shimano Deore 9-speed derailleur gear harmonise perfectly with the hydraulic Magura MT4 disc brakes. Schwalbe G-One Tires in a width of just 40 mm accentuate the unadorned appearance. Its short stem provides high-speed, agile riding behaviour.

"If you can fit the Schwalbe G-One tyres in your frame, you should get some. As genuine all-rounders they're impossible to beat right now: fast rolling on tarmac and properly capable off-road. They're really, really good." Road.cc magazine review


Drive: New for 2017, the Bosch Performance Speed motor system can put out a whopping 60Nm of torque and a top assist speed of 28 mph.  The Performance Speed motor features a composite shell and has been recognized with the Red Dot Award for outstanding product design. The drive unit is equipped with an electronic control system with three sensors for force, cadence and speed, ensuring optimal coordination. It takes 1000 sensor measurements per second. That's why all Riese & Müller E-Bikes are equipped with the industry-leading Bosch drive system.

Battery:  The battery is impressively easy to use. With a capacity of 13,4 Ah, this premium lithium-ion battery has an energy reserve of 500 Wh and is designed to be mounted on the carrier. Bosch has made it easier to predict your useful range with their online range calculator. Thanks to an integrated locking system, the battery can be removed and re-attached just like any “plug & play” device and can be completely charged with the Bosch Standard charger provided, the 500 Wh battery is fully charged and ready to be used again in just 4.5 hours.
