What are the different types of gearing systems?

Which gear system suits you best depends on how, where and how often you ride. At Hase Bikes you can choose between different gear types that differ in three basic points:

Derailleur or hub gears
Derailleur gears offer a particularly wide gear range and are ideal for sporty riding, climbs or heavy loads. As fewer components are in motion, they provide higher efficiency compared to hub gears. They can also be shifted under load. With their closed design, hub gears are particularly low-maintenance and allow shifting when stationary – perfect for everyday use and longer tours.

Mechanical or electronic shifting
Mechanical gears are operated via traditional cables, are robust and simple in design. Electronic systems shift precisely at the touch of a button, sometimes even automatically – ideal for consistent riding without manual intervention.

Manual or automatic shifting
With manual gears you decide yourself when and how to shift. Automatic systems take over the shifting for you and select the right gear automatically depending on speed, cadence or terrain.
Here you will find an overview of all gear systems – with advantages, functions and the Hase Bikes models in which they can be installed.

In addition to the different systems, the gear range plays an important role when choosing the right gear system. The gear range indicates the difference between the easiest and the hardest gear. A high gear range of e.g. 500% means you can climb steep hills easily as well as ride efficiently at high speed.

Mechanical hub gears

With mechanical hub gears the gear change is made by twist or lever and transferred to the hub by a cable. The mechanical hub gears used in Hase Bikes are shifted manually. They convince with simple maintenance and reliable gear changes – while riding or when stationary.

stepless shifting – 380% gear range

The Enviolo hub gear works entirely without fixed gears, using a stepless principle. Operation is via an intuitive twist grip that lets you continuously adjust the ratio without defined steps. You can always select the ratio that suits your riding situation. Shifting is possible at any time, even under load and when stationary.

Advantages of the Enviolo stepless gear
  • seamless: no interruptions in power when shifting, possible under load and when stationary

  • manual steplessness: with the simple twist grip you can set infinite “gears” – ideal for every situation

  • robust: reliable power transmission in a closed gear construction

14 gears – 526% gear range

The Rohloff Speedhub is a high-end gear hub with 14 real gears and an extremely wide gear range of 526%. It impresses with very fine gear steps, direct shifting and virtually maintenance-free operation. Ideal for long tours and the highest demands.

Advantages of the Rohloff Speedhub 14-speed
  • enormous gear range: with 526% the hub gear offers a range normally only achieved by derailleur systems

  • fine gradation: 14 gears, shifted by twist grip, so you always have the right cadence

  • robust & durable: made in Germany, virtually maintenance-free, extremely long-lasting

  • high efficiency: very low energy losses, comparable to a high-quality derailleur system

8 gears – 307% gear range

The Nexus 8 is a robust hub gear with 8 speeds, ideal for low-maintenance operation. It offers a wide gear range in a compact design and allows shifting even when stationary. Special tooth profiles ensure smooth gear changes.

Advantages of the Shimano Nexus 8-speed hub gear
  • good gear range: approx. 307% for sporty riding and relaxed cruising

  • comfortable shifting: reliable gear changes even in rough use

  • for e-bike motors up to 60 Nm torque

Electronic hub gears


With electronic hub gears shifting is performed at the press of a button or even fully automatically. The motor software and the gear system work together: the electronic gears are directly connected to the drive and exchange data continuously to optimise shifting according to riding conditions.

Shimano gears harmonise perfectly with Shimano drives. Bosch e-bike motors also communicate smoothly with Rohloff and Enviolo gears.
