About the manufacturer:

Riese&Müller is not competing for the award of the lowest-priced electric bike. They want to sell the best quality electric bikes available, and they do this excellently in the category. High quality, comfort center, illustrative design, premium components. The latter are the most characteristic features when we think of Riese&Müller.

How to use the bike:

We recommend this bike primarily for hiking or everyday use. Thanks to the geometry, we can comfortably ride long distances without back pain. Due to its equipment, it can stand up to any time of day and weather, so it's up to us when we jump into the saddle.

About the motor:

The fastest and most powerful Bosch motor. The 45 km/h version of the fourth-generation Performance Line drive unit with the Smart System. The maximum 85 Nm of assistance can deliver 340% of human power. The lightweight, 2.9-kilo motor can be driven completely without resistance, so we can easily drive our bike with the assistance turned off or with a flat battery. Attention! Since this motor helps you up to 45 km/h, the bike belongs to the S-pedelec category, which is subject to the rules for motorized bicycles. Before buying, be sure to check the rules, or ask our colleagues for help with information!

The display:

The advanced version of the mature KIOX with Smart System. The small, compact, durable display can be customized to your needs, so you can always easily track the information that is important to you. The display, like its predecessor, has clear navigation, which can be started within the Flow application. Its glare-free display is easy to read at any time of day.
