Technical Specification

Tern Verge D9 FOLDING BIKE

The Verge D9 is a trailblazer. Born out of our 451 Verge design philosophy, it has bigger race wheels, T-Tuned™ geometry, and a wide 1x drivetrain. It’s about as much value as we could condense into one bike, and it’s ready for any upgrades you can throw at it.

OCL+™ FRAME JOINT

A heavy-duty update to our iconic OCL frame hinge, the OCL+ is built to exceed ISO 4210 and EN 15194 testing requirements. Leveraging the hinge design of the long-tail Tern Cargo Node, the OCL+ features a single-shaft design, advanced welding techniques, and robust gussets, so it stays stiff and strong during even the fastest commutes.

PHYSIS™ 3D HANDLEPOST

Five patented technologies and unique manufacturing technology add up to the strongest, stiffest folding handlepost available. The Physis uses a special manufacturing process called 3D forging, which forms the post from a single piece of aluminum, eliminating all welds.

SYNTACE VRO STEM

Your bike should adapt to fit you―not the other way around. This adjustable stem allows you to position your handlebars further, for a more stretched and aggressive riding position, or up higher for increased comfort.

SHIMANO HYDRAULIC DISC BRAKES

Shimano hydraulic disc brakes deliver powerful stopping power in all weather conditions with the touch of a finger.

SHIMANO SHADOW DERAILLEUR

Originally developed for mountain bikes—for extra durability and to avoid catching on trail debris—the Shadow derailleur is streamlined and incredibly resilient, which comes in handy when you need to transport your folded bike. Whether your bike is bagged on the subway or riding in the trunk of your car, everything is neatly tucked away.

1X (“ONE-BY”) DRIVETRAIN

There’s a revolution in drivetrains across the industry. Thanks to the recent introduction of hyper-wide cassettes from SRAM and Shimano, it’s possible to achieve massive gear ranges with only one chainring up front. That makes 1x an ideal configuration for folding bikes, because it reduces maintenance, weight, and complexity. Enjoy all the range of a 20-speed drivetrain, with none of the complications.
