Cassettes for electric mountain bikes are specially designed to meet the requirements of electric motors, which increase power and place greater demands on the E-MTB drivetrain. They differ from conventional cassettes by their robustness, their ability to adapt to the high torque of motors, and their compatibility with modern transmission systems.
1. Types of cassettes for electric mountain bikes
a. 11 speed cassettes
Features :
Wide development range (often 11-50 teeth).Designed for smooth transmission on varied terrain.
Specificities:
Compatible with conventional transmissions and certain engines.Perfect for cyclists looking for a good compromise between weight and versatility.
b. 12 speed cassettes
Features :
Extended developments up to 52 teeth.Optimized for modern drivetrains (SRAM Eagle, Shimano Hyperglide+).
Specificities:
Allows you to effectively manage steep slopes thanks to a wide gear range.More suitable for high-end systems.
c. Specific E-MTB cassettes
Features :
Reinforced teeth to handle the high torque generated by the electric motor.Designed for intensive use and difficult conditions.
Specificities:
Ultra-resistant materials to limit premature wear.Gear range often optimized for the specific needs of electric mountain bikes.
2. Technical characteristics of an electric MTB cassette:
Development range:
Typically between 11-50 teeth or 10-52 teeth, allowing for great versatility on rough terrain.Compatibility:
With HG (Shimano), XD (SRAM), or Micro Spline freewheel bodies depending on the model.Some models specific to Bosch, Shimano Steps, Brose, etc. motors.
Materials:
Mixture of steel (for durability) and aluminum (to reduce weight).High-end cassettes include special alloys for a better weight/strength ratio.
Weight :
Varies between 400 g and 600 g depending on the range and materials used.Surface finishing :
Specific coatings to limit corrosion and increase durability.3. Popular brands and reference models of electric mountain bike cassette:
a. SRAM
Models:
SRAM GX Eagle E-MTB: 12-speed cassette, 10-52 teeth.SRAM EX1: Specifically designed for electric mountain bikes, 8 speeds (11-48 teeth).
Specificities:
Smooth and precise transmission, even under high load.Robust and ideal for powerful engines.
b. Shimano
Models:
Shimano Deore XT CS-M8100: 12-speed cassette, 10-51 teeth.Shimano Steps E8000: Cassette optimized for Shimano electric systems.
Specificities:
Hyperglide+ technology for fast, smooth gear changes.Durable construction for heavy duty use.
c. SunRace
Models:
SunRace CSMZ90: 12-speed cassette, 11-50 teeth.SunRace MS8: 11-speed version, suitable for electric mountain bikes.
Specificities:
Economical alternative offering good durability.Wide compatibility with various systems.
d. E*Thirteen
Models:
E*Thirteen TRS Plus: 12-speed cassette, 9-46 teeth.E*Thirteen Helix: Compatible with SRAM and Shimano systems.
Specificities:

European manufacturing with robust materials.Excellent alternative for cyclists looking for a durable and accessible product.
4. Points to consider before purchasing an electric mountain bike cassette:
Compatibility:
Check the freewheel body type and transmission system of your electric mountain bike.Gear range:
A wide range (e.g. 10-52 teeth) is ideal for mountainous terrain.Sustainability :
As electric mountain bikes place greater demands on cassettes, choose reinforced models.Usage:
For leisure use, a mid-range cassette is sufficient.In competition or intensive use, opt for premium models.
5. Conclusion :
E-MTB cassettes play a crucial role in drivetrain efficiency and adaptation to varied terrain. Brands like SRAM and Shimano dominate the market with their innovative and robust models, while options like SunRace or Miche offer budget-friendly alternatives. By choosing an e-MTB cassette adapted to your engine and your practice, you will ensure optimal performance and increased durability.
