Information
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.
- New colors and updated styling
- Verge quality, style, and performance at an entry-level price point
- Shimano hydraulic disc brakes for all-weather stopping power
- Folds in under 10 seconds—fits under a desk
- Rides with exceptional comfort and stability thanks to our unique technology and T-Tuned geometry
- 451 wheels deliver a full-sized ride with minuscule impact on the folded size

TECHNOLOGY

OCL+™ FRAME JOINT
ROBUST FOLDING TECHNOLOGY
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.

DOUBLETRUSS™ TECHNOLOGY
STIFFER BY DESIGN
The rear half of Tern frames use a patented 3D structure we call DoubleTruss to build in extra stiffness. It helps resist torsional forces so our bikes flex less. That means increased stiffness and much better power transfer from the pedals to the rear wheel. The proof’s in the ride.

T-TUNED™ GEOMETRY
FULL-SIZED RIDE, COMPACT FOLD
At Tern, we endeavor to build fast-folding bikes that ride like full-sized bikes. Our T-Tuned geometry is the culmination of our commitment. We’ve tweaked the wheelbase, rake, and seat-tube angle of our design to deliver the most confident and stable ride of any bike in our lineup. Ride one and try it. Take your hands off the handlebars if you’re feeling bold.

PHYSIS™ 3D HANDLEPOST
THE NEW BENCHMARK
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.
