In theory a chain can be up to 99% efficient. In practice, a clean modern chain can easily hit 95%. Chains are by far the most efficient drivetrain.

- asdff 4y agoHow do belt drives stack up? I see more ebikes going belt drive which makes me think theres some efficiency gain there or at least its able to handle more torque perhaps.
- bryanlarsen 4y agoBelt drives are less efficient than a well maintained chain but more efficient than a poorly maintained chain. E-bikes are less concerned about maximal efficiency and more concerned about ease of use. Belt drives don't need cleaning and greasing like chains do.
- masklinn 4y agoebikes go belt drive for ease of maintenance and replacement, not for efficiency (they care much less since the motor compensates). The elasticity of the belt could also be an advantage if the engine is at the pedals (rather than in the hub), as it would allow for a less smooth engine programming, using the belt’s elasticity to absorb some of the harshness.
