About the manufacturer:

Our story begins in 1993 in the garage of Heiko Müller's parents. Markus Riese and Heiko Müller's love for bicycles led to the creation of what is now a gigantic brand. The pair, who have formed a strong friendship to this day, initially created a folding bicycle, which they named Birdy. Today, Riese&Müller has become one of the market leading brands in the field of electric and cargo bicycles. They started producing electric bicycles in 2013. Their main task is to continuously improve and create a better cycling future.

How the bike is used:

They are located between off-road and street machines. The 28″ wheel diameter stands its ground on asphalt or medium-difficult terrain (forest paths, dirt roads). Comfortable and light, making them the best for long-distance trips. Most models have a luggage rack and mudguards.

About the engine:

The most powerful of the Bosch engines, turbocharged with the Smart System. This fourth-generation 85 Nm motor is capable of 340% assistance, which is more than three times the power of a human. With this drive unit, we can easily ride anywhere, but we can use its power best on steep climbs. The motor has zero resistance, so it can be cycled without any problems even with the assistance turned off or with a discharged battery.

The display:

An improved version of the previous Kiox display. It contains countless information that can be accessed by turning different pages. The pages can be customized, so that the information that is important to us can be displayed. It can also be operated as navigation, which can be started via the Ebikeflow application. The display is glare-free, so you can easily read the data at any time of day.
