An E-bike derailleur generally performs the same functions as a traditional city e-bike, but it can have certain specific characteristics to adapt to electric motorization and the specific needs of urban cyclists. Here is a description of the function, characteristics and standards of electric bike transmission derailleurs:
Function of an E-bike derailleur :
The e-bicycle derailleur is an essential component of the transmission which allows you to change speeds by moving the chain from one cog to another on the cassette at the rear of the bicycle. Its main function is to allow the cyclist to adapt to different types of terrain and riding conditions by adjusting the resistance and pedaling speed.
Characteristics of an E-bike derailleur:
1. Electrical Compatibility:
Electric city bike derailleurs can be designed to work with electric drivetrain systems, although many electric city bikes use integrated hub drivetrains, meaning the derailleur is less crucial for shifting.
2. Robustness and durability:
As with all city bikes, robustness and durability are important characteristics for the electric bike derailleur, as it can be subjected to difficult urban riding conditions.
3. High Torque Capacity:
Electric derailleurs often feature stronger springs and oversized pulleys to handle the increased tension.
4. Chain Stabilization Technology:
Integration of systems such as cage stabilization (Shadow+ at Shimano) or chain clutches (clutch at SRAM) to avoid derailments.
5. Increased waterproofing:
Resistance to splashes of water, mud and dust, essential for use off-road or in bad weather.
6. Engine Compatibility:
Some derailleurs are specially designed to be compatible with motor systems (Bosch, Shimano Steps, Yamaha, etc.).
Types of derailleurs for e-bikes
Mechanical derailleurs:
Classic operation with cables.Advantages: Simplicity, easy maintenance, affordable cost.
Electronic derailleurs:
Control via electronic levers or wirelessly.Advantages: Ultra-precise gear changes, automatic adjustments, connection with electric assistance.
Integrated derailleurs:
Derailleurs specific to internal transmissions (Ex.: Rohloff or Enviolo).Advantages: Reliability, reduced maintenance, ideal for urban and trekking bikes.
