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.
Four patented technologies and unique manufacturing technology add up to the strongest, stiffest 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.
To eliminate flex, the Physis was designed with a massive joint knuckle and a post that gradually tapers from thick at the base to thin. The fork steerer interface is 150% more stiff than common designs.
The base of the Physis is machined so it functions as the upper race of the headset. This patented direct integration contributes to the incredible stiffness of the design.
Joint surfaces lock together to improve torsional stiffness.
Two bolts clamp the Physis to the fork steerer for improved safety.
The patented design puts sliding bearings between the moving parts so the folding action is always smooth and friction-free.
Large rounded surfaces are easy on your hands and provide good leverage for easy operation.
Close the lever and it automatically locks in place, for extra, easy security.
Patented technology allows the lever to fold flat and brace against the joint for protection in transit.
Good things are built to last and that’s why the Physis is designed to be fully dealer serviceable. We keep every part in stock and replacing the bearings can be done in minutes.
Three rubber seals keep weather out and the headset bearings functioning smoothly.
A machining tolerance of only 50 microns ensures a tight fit and eliminates looseness and rattling.
Cold-worked stainless hardware delivers the durability and reliability needed for daily riding.
The Physis features a unique patented geometry with a forward facing hinge for additional safety.
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.
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.
