Why did you choose to use a carbon belt drive?

The carbon belt drive delivers a completely oil-free drivetrain. It just makes perfect sense for a folding bike; why build a bike that’s dirty when you can build a bike that’s completely clean. In addition, the belt is smooth, silent, doesn’t stretch and lasts for at least 60,000 miles (100,000kms).  In fact, we believe in the carbon belt drive so much, that if it breaks or wears out, we will replace it completely free of charge.
