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. There are conventional derailleur gears with cables and manual actuation of the rear derailleur and also electronic ones. In this case, instead of a shift cable, a standard cable is routed through the frame. By gently tapping the switching buttons on the handlebar, the desired gear is automatically shifted to quickly and precisely.

Shimano Deore

Our touring and mountain models are equipped with a Shimano Deore or Deore XT with 10 or 11 gears, depending on the model and series. The Deore series from Shimano has been on the market for more than 30 years and undergone constant optimisation and development in that time. It impresses with its tried-and-tested technology and its great reliability, high-quality workmanship and easy operation. As a result, Shimano Deore gears have proven themselves for many decades and indispensable premium components in the E-Bike area.

Shimano XTR Di2

With the Shimano XTR Di2, the Delite GTS has one of the best electronic derailleur gears on the market. It allows extremely fast and precise shifting and is particularly resistant to dirt, which is a major plus especially when riding offroad. In addition, no tensile wear occurs any more during shifting, as the XTR Di2 works completely without shift cables. The gear system is fully integrated; power is supplied directly by the E-Bike battery.

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 R&M Custom

Instead of lots of complex cogs and components, the Enviolo 380 R&M Custom uses rotating and incline-adjustable balls that are positioned between two discs. This makes it easy to shift while stationary. With the Enviolo 380 R&M Custom 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 H-Sync 380 R&M Custom

The version with automatic shifting boasts even greater comfort – the Enviolo H-Sync 380 R&M Custom. 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 Nexus

The reliable Shimano Nexus 8-speed hub gear with coasting is operated via a comfortable twist grip on the handlebar. This hub gear is very low-maintenance and therefore perfectly suitable for riders who want to deal tend to gear maintenance as little as possible. You can shift gears even while stationary. Some city models are optionally available with a back-pedal function, for a safe feeling 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 – currently the fastest gear shift on the market. 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.

Shimano Alfine Di2

On some Roadster models, we install the ultra-modern, electronic Shimano Alfine Di2. The name stands for “Digital Integrated Intelligence”: The gears are changed fully automatically in the push of a button, entirely without cables. With its stylish design, Alfine Di2 also perfectly matches the Roadster and adds to the overall minimalist image. And thanks to their high resistance and durability, you will take pleasure in this sophisticated gear-shifting system for a long time.
