Will belt drives replace chains on eBikes?
What is a belt drive?
A belt drive bike uses a belt as opposed to a chain. Belt drive bicycles were first introduced in the 1980s and since then, have been paired with hub gears for riders looking for multiple gear ratios. Belts are most commonly made out of nylon reinforced with carbon fiber cords making them one of the most durable options to power the drivetrain - after all, it is even used on motorcycles! We’ll take a look at some of the pros and cons of a belt drive and determine if it will eventually replace traditional chains.
What are the pros of a belt drive?
- No rust
- Buttery smooth while peddling
- No lubricant needed
- Less maintenance
- Extremely durable (can last 5-10x longer than chains)
What are the cons of a belt drive?
- Can only be used with a single gear or hub gear
- Can be harder to replace
- More expensive
- Belts cannot be repaired and only replaced
- Less efficient at low power outputs
