Verge X10

Shorten the Commute

Lots of times, people think good product design is adding more features. We’re the opposite. We figure out what the product is for and then take out all the extraneous stuff. This is the bike for city riders looking for something really light, really fast, really portable and made from top quality stuff so they can get where they are going, fast. Nothing more.

New! Kinetix Pro X wheels & Tarsus hydroformed fork.

N-Fold Technology

The Faster Fold

Folding bicycle design hasn’t changed much in decades. N-Fold Technology is a small but important change that results in a faster, and more compact fold. N-Fold Technology includes new frame and handlepost geometries and spins the front wheel by 180 degrees before the central fold, resulting in a package 40 mm (1.5") shorter. Using N-Fold technology, our bikes are only very slightly larger than the typical small wheel folding bicycle. Bicycles with N-Fold technology can also be folded – easily – in less than ten seconds.

OCL Joint

Stronger, Better, State of the Art

The OCL Joint is a new reference in folding frame technology. It includes two new patents and everything we know about making the safest, strongest, and most durable frame joint.

  • Stronger, Stiffer — Making the hinge taller and moving the pivoting surfaces outward from the center axis more than doubles overall strength and stiffness and it’s a difference you’ll feel from your very first ride.

Stronger by Design

Folding bikes have a sometimes deserved reputation for flexy frames. All Tern frames feature patented DoubleTruss technology which turns the rear half of the frame into a three dimensional truss so that it’s much more resistant to torsional forces.

Traditional bike frame seat stays start at the seat tube to create the rear half of the bike. On Tern bikes, the seat stays form a rigid triangle with the seat tube to fashion a continuous structure that extends to the rear axle.

Igus Bearings

Smooth Operator

When we find a way to make our frame and handlepost hinges better, sometimes we get a little crazy. That’s what happened when one of our friends suggested we have a look at Igus bearings. Igus says they are in business “to use its innovative polymer materials to develop products that provide creative solutions.” Man are they right. This ultra durable engineering plastic is amazing. No rusting. No grease required. Amazing durability. We now use super smooth Igus bearings in FBL 2.0, Physis and OCL joints. We make bikes to last long, designed for easy maintenance.

Tarsus Fork

Hydroform Meets Function

The Tarsus fork uses a single piece of hydroformed tubing that is shaped to form the fork blades, shoulder and crown. Hydroforming allows us to optimize wall thickness and align metal grain structure for a fork that is light AND incredibly strong.

Plus we’ve built in internal wire routing so you can send power from a dynamo hub up to your light right inside the fork blade. And we made the front Magnetix mount serviceable so in the unlikely event that something goes wrong, it can be replaced.

Physis 3D Handlepost

3D-Forged = Even Stronger, Stiffer, Better Ride

Flexy handleposts and noodly handling are the Achilles heel of many folding bicycle designs. The Physis 3D handlepost solves this with a massively strong, precision machined design that virtually eliminates flex. The Physis is 3D-forged from a single piece of aluminum, eliminating welds to give a stronger, lighter, and more cost-effective part.

The Physis uses four patented technologies and is 100% serviceable, so all parts can be replaced if needed. It has igus™ bearings for smooth operation and rubber seals to protect headset bearings.

Syntace VRO 47 Stem

Fitted to You

The VRO 47 stem fine-tune your riding position for speed or comfort. The stem is 47 mm long (14 mm longer than the standard VRO) and it’ll go anywhere from -45 degrees to +90 degrees or even backwards if you want to reduce the reach. And it exceeds Syntace’s brutal in-house test procedures for downhill gear. Custom-built for Tern.

Syntace is a German company renowned for their incredibly light but amazingly strong stems and bars. The Syntace VRO handlebar system used on select Tern bikes allows adjustment of handlebar height and reach for perfect rider fit.

Kinetix Pro X Wheels

The New Standard

Our new Kinetix Pro X wheels set a new standard for 20" wheels. Custom 27mm rims are taller for strength and more slippery aerodynamics. Custom-forged Sapim aero spokes are straight-pull for improved durability and laced in a patented Rolf paired-spoke pattern for strength. Custom hubs feature precision CNC machined flanges for perfect spoke alignment. Individually built and tuned by hand. 1100 grams light. Tested to EN standards for strength and durability. Light, fast, AND durable.

"This bike is featherweight, lightning fast, and tough enough to take on rough terrain and city potholes. Best of all, it folds up superfast, so you can easily carry it into your building or stow it in your truck."
November 11, 2013

"This Tern bike is a dream come true for someone in search of a folding ride that doesn't sacrifice the feel or speed of a normal bike. Putting 40+ miles on this bike comfortably wouldn't be out of the question - something that can't be said for most folders."

"The Verge X10 is an awfully quick little rig, scooting forward with each pedal stroke and maintaining a healthy clip in an efficient-feeling manner that's more befitting of a mid-ranged road bike than something intended for commuting. Perhaps most telling is the fact that we often grabbed the Verge X10 if we were running late for something (which was pretty much always)."

"Die Lösung heißt Faltrad, denn das darf man immer und kostenlos in den Bahnen mitnehmen."
January 16, 2013

"The Verge Duo seeks to marry performance, low maintenance and sleek lines, and does so extremely well. Tern have redesigned certain aspects of the frame to make them stiffer while making the fold even quicker. We were particularly impressed with the extremely strong and stiff Physis handlepost joint. The result is a bike that folds to a reasonably small size (easily little enough to pop in a train luggage rack) but is a blast for quick rides around town."

Folding Bikes

"Like all the folding bikes in the Tern Verge Series, the Verge X20 is exceptional, a show-piece and speed demon wrapped in one. So far I have taken it on three semi-major rides and the attention it gets is hard to miss. I’m glad I can take it in with me wherever I go, because those looks of jealousy might turn on me."

"What surprised me the most, was the Kinetix pro wheelset and the stock-standard Schwalbe Durano tires. I’ve underestimated them, thinking that it was flimsy and unable to take my weight. With a Godzilla-sized rider like me, the rims and tires were able to withstand our harsh road conditions. Not only that, its capable of yielding 25km/h on the average with little effort. So, imagine if you are really fit and have the power to weight ratio. This bike will fly!"

"Setup couldn't be simpler: Flip a lever to unfasten the main body and fold the bike in half, flip a level on the handlebars to fold those down, push in the pedals, and lower the seat . . . the Verge Duo was a comfortable breeze to drive around bumpy, hill-heavy Brooklyn bike paths. Finally, at less than $1,000, it's a steal when compared with its pricier U.K.-built competitors."

"This goes to say that the combination of a lightweight frame and high-end groupset actually helped the bike to perform better. If you are a strong cyclist, all you need is this bike as its 10-speed drivetrain would take you places."

"The hub tended to shift just when I would have shifted manually . . . DC is a relatively flat city, so I never experienced a disagreement with the bike about what gear it should be in."
