The perfect gear for every pace.

Whatever your plans and your expectations, you will find the perfect gear among the Riese & Müller e-bikes. Different versions of comfortable hub gears and sporty derailleur gears make for a broad and very customisable range of equipment. Whether you want to go on long tours, you’re mainly on the go in the city or you want to go offroad with your e-bike: our bikes and gears are always perfectly coordinated with each other – and to meet your needs.

Derailleur gear

A well-maintained derailleur gear has the best degree of efficiency of all the possible types of transmission. This is important for sporty riders who want to eke every last metre of range from their e-bikes.

Shimano Deore, Microshift and Cues

Shimano’s Deore range has proved itself for many decades and has been continuously optimised and developed since its launch. It impresses with its tried-and-tested technology, excellent reliability, high-quality workmanship and ease of use. The comparable Microshift gear with 10 gears is used with some models. The design of the Shimano Cues gear extends the service life of the chain and sprockets – significantly reducing signs of wear. 

Hub gear

Hub gears are hugely popular thanks to their low maintenance requirements and easy, highly comfortable operation. In contrast to the derailleur gear, the shifting process is not performed by shifting the chain but occurs within the hub in the middle of the rear wheel. As this is a closed system, the gear is protected from moisture and dirt at all times. This type of gear also allows the use of a modern, lightweight and particularly quiet-running carbon belt drive.

Enviolo 380

Instead of lots of complex cogs and components, the Enviolo 380 uses rotating and incline-adjustable balls that are positioned between two discs. This makes it easy to shift while stationary. With the Enviolo gear hub, you always ride with the perfect gear ratio without any gaps between shifts, because through an infinite number of gears within a gear ratio range of 380 %, shifting is a very smooth process. Its simple operation with the rotating handle on the handlebars means that the perfect gear can be selected intuitively. Thanks to the lack of gear jumps, the riding comfort is markedly increased compared to conventional gear changes.

Enviolo automatiq

The version with automatic shifting boasts even greater comfort – the Enviolo automatiq. Simply select the ideal pedalling rate for you and the system automatically determines the right gear and shifts for you. This way, you can tackle any incline feeling completely relaxed, without ever getting out of breath. Even after short interruptions to riding, for example at traffic lights, you automatically shift back to the perfect gear. You can adjust the pedal frequency at any time as required via the Bosch E-Bike display and external control unit.

Shimano Alfine and Nexus

The reliable Shimano Alfine and Nexus 8-speed hub gear with coasting are operated via a comfortable twist grip on the handlebar. These hub gears are very low-maintenance and therefore perfectly suited to riders who want to deal tend to gear maintenance as little as possible. You can shift gears even while stationary. Certain models are available with a coaster brake function, for a safe ride in all situations.

Rohloff Speedhub

Riders who are often on tour and cycling through hills need a broad range of gears. The Rohloff Speedhub – a 14-speed hub gear with over 520 % performance – is therefore optimally suited to enable even the steepest ascents with no sweat. With its extremely high degree of efficiency between 95 and 98 %, it is in no way inferior to modern derailleur gears. However, thanks to its fully closed design, it is significantly lower-maintenance, while the gear-shifting using the twist grip on the handlebar is even more comfortable. In normal use, it requires no re-adjustment for many thousands of kilometres. Like all Rohloff hubs, the Speedhub shifting unit is precision-manufactured in Germany and thus guarantees maximum reliability and a very long service life.

Electronic Rohloff E-14

The electronic Rohloff E-14 gear links the mechanical Rohloff Speedhub 14-speed gear hub to the eShift function of the Bosch e-bike system – an electronic gear shift activation unit. The drive and gear communicate with each other and synchronise the gear-shifting process to make it as light, precise and efficient as possible. An ergonomic switch with two buttons replaces the twist shift grip and gear cables. You can now shift gear in less than 200 ms – and that’s with a 526 % gear ratio. Multi-shift mode simultaneously shifts 3 gears in a single sequence, while the auto-downshift function automatically returns the gear to your individually selected starting gear when the bike comes to a standstill. Especially when teamed up with the Gates carbon belt drive, the E-14 makes full use of its advantages.

Singlespeed

The singlespeed models of UBN bikes offer riding enjoyment at its purest. As a rider, you benefit from minimal maintenance combined with low weight, thanks to the Gates CDX belt drive and absence of gears. The benefits of singlespeed models truly come into their own when riding on flat urban streets. 

Carbon belt drive

Clean, quiet-running, powerful, maintenance-free  these are the advantages boasted by the Gates carbon drive system. An innovative bike drive that requires no lubrication, never rusts and lasts much longer than most chains. Lubrication-free, the belt is made from carbon fibres with extremely high tensile strength. Whether in town or in the country, offroad or onroad, with the Gates carbon drive you can reach any destination any day and in any weather.

Pinion gearbox technology

The Pinion E-Drive System combines a powerful electric motor, proven gearbox technology and electronic gear shifting to form a perfectly coordinated package. Power is transferred only via the respective two gear pairs in each gear. This results in a consistently high degree of efficiency, minimal noise levels and a direct riding experience with no loss of power. All gears can also be shifted through while stationary one by one or by skipping through the gears. The lightweight belt drive stands out with its long service life and minimal maintenance.
