The Tern Verge D9 Folding Bike with 22 inch Wheels 9 Speed is a trailblazer. Born from Tern's 451mm wheel rim Verge design philosophy, it has bigger race wheels, T-Tuned geometry, and a wide 1x drivetrain. Its about as much value as they could condense into one bike, and its ready for any upgrades you can throw at it.
