The electric bike drivetrain is an essential element, ensuring good interaction between the motor, the pedals, and the rear wheel. Depending on the type of use (city e-bike, mountain bike, gravel or road), it can vary considerably in terms of technologies and brands. Here's a detailed guide to understanding e-bike drivetrains.
Types of electric bike drivetrain
1. Classic transmission with derailleur
Features :Using a rear derailleur to change gears.
Commonly associated with 8 to 12 speed cassettes.
Works well for urban, gravel and mountain e-bikes.
Advantages: Lightweight, wide speed range.
Disadvantages: Requires regular maintenance.
2. Internal hub transmission
Features :
The gears are integrated into the rear wheel hub.
Often associated with a belt to limit maintenance.
Advantages: Reliability, low maintenance, ideal for urban bikes.
Disadvantages: Slightly heavier weight, limited speed range.
3. Automatic transmission
Features :
Automated gear change based on pedaling cadence or power applied.
Present on some high-end bikes.
Advantages: Comfort and ease of use.
Disadvantages: High cost, less widespread.
4. Assisted electric transmission
Features :
Combined with an electronic derailleur for precise gear shifting.Compatible with systems like Shimano Di2 or SRAM AXS.
Advantages: Speed, precision, customization via applications.
Disadvantages: Higher price.
Characteristics of electric bike transmissions
Engine Compatibility:
The transmission must be designed to handle the high torque produced by electric motors, especially for MTB models.Reinforced cassettes and chains are essential to prevent premature wear.
Speed range:
Drivetrains with a wide range (10-50 teeth) are ideal for mountain biking or varied terrain.Urban bikes often favor a smaller range for simplicity.
Durability and maintenance:
Belt and internal hub transmissions require less maintenance than traditional systems.Electric bike chains and sprockets need to be maintained regularly to handle the added stress.
Weight :
Hub systems are generally heavier than external derailleurs, but their strength makes up for this disadvantage.The best electric bike drivetrain brands
1. Shimano
Range :
Shimano Deore and XT for electric mountain biking.
Shimano Nexus (internal hub) for urban bikes.
Features :
Reliable and versatile systems.
Compatible with most central motors like Shimano Steps or Bosch.
2. SRAM
Range :
SRAM Eagle AXS for electric mountain biking.
SRAM EX1 specially designed for electric bikes.
Features :
Light and robust transmission.
Precise gear shifting, even under heavy load.
3. Rohloff
Range: Rohloff Speedhub (internal hub).
Features :
Integrated 14-speed hub, ultra-durable and ideal for electric trekking bikes.
Excellent speed range.
4. Enviolo
Range: Automatic and continuous transmission.
Features :
Hub with progressive gear change, ideal for urban bikes.
Works perfectly with belts.
5. Gates Carbon Drive
Range: belt transmission.
Features :
Replaces the chain for a grease-free and almost maintenance-free solution.
Ideal for urban and trekking bikes.
Tips for choosing your electric bike drivetrain:
Determine your main use: urban, off-road or mixed.
Consider maintenance: An internal hub is easier to manage for everyday use.
Check compatibility with your engine: Some transmissions work better with specific engines.
Consider durability: Opt for reinforced components if you ride regularly.
Conclusion :
The electric bike drivetrain is a key element to maximizing your experience with an electric bike. Depending on your type of use, you can opt for a classic, hub or electronic system. Brands like Shimano, SRAM, Rohloff and Enviolo offer suitable solutions for all needs. Take the time to choose the transmission that best suits your driving style and your expectations in terms of comfort and performance.
