When buying an electric bike, many people focus on the motor, battery, and brakes, but overlook the drivetrain.
Simply put: if you’re commuting and don’t want to deal with maintenance, go with a belt drive; if you’re on a tight budget and frequently ride uphill, go with a chain drive.
Chain drive — proven technology, affordable, and easy to maintain
✅ Any bike shop can repair it, and parts are inexpensive
✅ High transmission efficiency, powerful on hills
❌ Requires regular cleaning and lubrication
❌ Prone to getting your pants and hands dirty
❌ Shorter lifespan (3,000–5,000 kilometers)
Belt Drive — Clean, quiet, and virtually maintenance-free
✅ No need for lubrication; won’t rust
✅ Long service life (15,000–30,000 km)
✅ Quiet and won’t get your pants dirty
❌ Costs $300–800 more
❌ Repairs require specialized parts
How to Choose?
Daily commuter who doesn’t want to spend time on maintenance → Belt drive
Tight budget, frequent hill climbing, and a DIY enthusiast → Chain drive
