Technology

N-Fold™ Technology

With N-Fold Technology, Tern bikes fold small and fast—in three easy steps. It’s simple enough for anybody to master. And with the handlepost folded to the outside of the package, Tern bikes can also roll when folded for easy transport.

OCL™ Frame Joint

The key to any folding bicycle is the frame, and specifically, the folding joint at the heart of the frame. Done well, it locks the two halves of the frame together without any hint of movement or sound. It should be easy to operate and work flawlessly year after year. The OCL Joint does all of these things and is a new reference in folding frame technology.

DoubleTruss™ Technology

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.

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.

Andros™ Stem

The Andros is our patented adjustable stem that lets you set your handlebars where you want—no tools, no fuss. In just seconds, you can set your riding position to long and low in a tough headwind, or upright and comfy for riding around town. You decide how you want to ride and the Andros makes your bike fit.

Schwalbe Kojak Tyres

Light and fast tyres with enough volume to keep things comfy. Kojak’s are ideal for fast commutes or longish weekend rides.

Shimano Claris 2 x 8 Drivetrain

Shimano’s Claris drivetrain is fast and smooth and serves up 16 well-spaced gears. It’s ideal for fast urban riding – with a few extra gears for those hillier routes.

TruShift Technology

Folding bicycles, with their unique geometries, pose difficulties for front shifting. TruShift Technology optimizes the critical elements so you get nothing but smooth front shifting.

Magnetix™ 2.0

The Magnetix 2.0 uses powerful magnets to keep your bike folded for situations like carrying your bike up and down stairs. With a pull force 10-15 Kgf, the Magnetix 2.0 will keep your bike folded even when being jostled and moved about.

Luggage Socket™

Fix the Tern Luggage Truss to the Luggage Socket and you can plug in your choice of front luggage: rack, basket, or bag. If it’s KlickFix compatible, it’ll work.
