Tern Bicycle - Folding Bike Latch

FBL™ 2 Frame Joint

Hidden benefits

3 patented technologies and incredibly precise manufacturing make the FBL 2 frame joint one of the best in the business. It’s strong, secure, and thanks to integrated bearings, always easy to use.

Smooth Operation

The patented design puts four igus® bearings between the aluminum and stainless steel moving parts so the folding action is always smooth and friction-free.

Interlocking Joint

The front and rear joint surfaces lock together to eliminate torsional movement.

Floating Point Technology

Patented technology allows the lever to fold flat and brace against the joint for protection in transit.

Serviceable

Good things are built to last and that’s why the FBL 2 Joint is designed to be dealer serviceable. We keep every part in stock and if your bearings ever wear out, your dealer can replace them in a few minutes.

Stainless Steel Hardware

Cold-worked stainless delivers the durability and reliability needed for daily riding in all weather conditions.

Tern DoubleTruss Folding Bike Design

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.

igus® Bearings

Smooth operator

German-made igus bearings make our frame joints the smoothest in the business. And, they’re dealer serviceable so that if they ever wear out, they can be replaced and your frame will be as good as new in just a few minutes.

Tern Q-Lock Folding Bicycle Technology

Q-Lock™ Handlepost

Quick locking

The Q-Lock is quick and easy to use: Close the handlepost lever and the AutoLock engages, holding the lever in the locked position. The Q-Lock is also safe and strong: it exceeds tough European EN standards for strength and durability.

Tern Magnetix for folding bikes

Magnetix™ 2.0

Keep it together

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.
