electric bike torque explained
Torque is one of the most misunderstood specifications in electric bikes. While motor power often gets attention, torque determines how the bike feels when accelerating and climbing hills.
What Is Torque?
Torque, measured in Newton metres (Nm), represents the rotational force applied by the motor. Higher torque means stronger assistance when starting or climbing.
Typical Torque Ranges
- 30–40 Nm: Flat terrain, light riders
- 40–60 Nm: Mixed urban riding
- 60–80 Nm: Hills, heavier loads
- 80+ Nm: Off-road and cargo applications
Why Torque Matters More Than Speed
UK e-bikes are speed-limited, but torque is not. This makes torque the key differentiator in real-world performance.
Matching Torque to Your Needs
- Commuters on flat routes do not need extreme torque
- Hilly areas benefit from higher torque
- Cargo, trailers, or heavier riders should prioritise torque
Torque vs Battery Consumption
Higher torque can increase energy use, but efficient riding habits and appropriate assistance levels balance this effectively.
The Bottom Line
Choose torque based on terrain and load, not marketing numbers.
