Technology

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.

BioLogic PostPump™ 2.0 Seatpost

You’ll always be prepared with this high-capacity floor pump hidden inside your seatpost. A true floor pump, it delivers a much higher volume of air than traditional mini-pumps, and the pumping action is easy—great for those high pressure or large volume tyres.

Tektro Hydraulic Disk Brakes

When you’re going fast, in all sorts of weather conditions, you need brakes that work, and work well. Tektro hydraulics fit the bill with sure, single-finger stopping power.

BioLogic Joule™ 3 Dynamo Hub

A hub dynamo is the ultimate green power source because it generates electricity while you ride—no batteries or recharging required. The Joule 3 is one of the very lightest and smallest dynamo hubs on the market and is one of only a handful that exceeds the High Efficiency (HE) 70% threshold. Say goodbye to batteries. Winner of a Eurobike award, the Joule 3 meets German StVZO standards for a 6V/3W hub—meaning it can power both a front and rear light.

Schwalbe Big Apple Tyres

Big Apples are special because they’re fast rolling AND super comfy. Sounds hard to believe but you’ll just have to take them for a ride to become a believer.

Xtracycle Kickback™ Kickstand

Traditional kickstands have their limits. This double-leg kickstand is robust and sturdy, providing you extra stability when loading or unloading your cargo. It retracts effortlessly with the included spring.

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.

Valo™ 2 Light

The Valo 2 is a powerful light designed to help you navigate safely at night. The unique design integrates directly into the handlebars of an Andros or VRO-equipped Tern bicycle so it’s protected from theft and damage. And because it’s hub-dynamo powered, you never need to worry about batteries or charging again. Flick a switch and you have instant light.

720° Visibility

You need to be safe when you’re out on the road. That’s why we’ve designed our hard-core commuter bikes with 720° Visibility: 360° of active lighting and 360° of reflectivity.

Xtracycle CarryAll™ Bags

These adaptable bike bags each feature a capacious cargo bay, an all-weather lid and a FreeLoader™ sling is designed to wrangle bulky things like surfboards.

Xtracycle Leap™ Rack

Built on 15 years of cargo-bike experience, the Leap is designed to be super strong and torsionally rigid so it won't flex or break under heavy loads—at any speed.
