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 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. 

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.
