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.

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 Eclipse and Castro 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.

  • Taller, 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.

DoubleTruss

3-D = Stronger

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. That equals increased stiffness and much better power transfer from the pedals to the rear wheel.

Smooth TIG Welding

Beauty Meets Function

The normal TIG welding process for aluminum bicycle frames is done by hand and involves the welder laying down a series of small, overlapping beads covering the two parts to be joined. The better the welder, the more uniform the beads. In the smooth TIG process, the welder makes a “double pass”, laying down a second layer of beads on top of the first. These beads are then sanded down by hand in an intensive process that requires extreme care. Done properly, the frame is strengthened because the possibility of stress risers is reduced. And the result is a very smooth weld joining the two tubes.

Physis 3D Handlepost

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

The Physis has quickly built a reputation as the stiffest folding handlepost on the market, but the Physis 3D takes it up a notch with 3D forging technology. The Physis 3D is forged from a single, solid block of aluminum. Only a small handful of factories around the world can 3D forge such a complicated, large piece. Welds are eliminated and material distribution optimized for strength. The result is a handlepost that is 2 1/2 times as strong as the original benchmark on rigorous EN tests. Plus, it doesn’t look half bad either.

Syntace VRO stem

Find Your Perfect Fit

The VRO stem from Syntace gives you all-important adjustability so you can fine-tune your riding position for speed or comfort –- whatever your heart desires. The stem is 33 mm long 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.

Syntace is a German company renowned for their incredibly light but brutally 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.

Stasis Seatpost by Syntace

Ultra-light, ultra-tough

The Syntace P6 is one of the strongest and precisely engineered seatposts on the market. We wanted the best so we worked with Syntace to develop a 580 mm seat post with a variation of their 3D cold-forged P6 clamp. Made from ultra-light 7075 aluminum and hard-anodized (black color option) for scratch resistance. ERS technology delivers loads of fore/aft adjustment for the saddle: you can run the saddle forward for zero offset stiffness, or all the way back like an offset seatpost. Two bolt micro adjust for infinite angle adjustment.

Kinetix Pro Wheels

Ultra-light, fast, aero

We wanted some really light, fast 20” wheels so we worked with Rolf Dietrich, one of the industries’ foremost experts on bicycle wheels, to develop this pair. Rolf was demanding: custom spokes from Sapim in Belgium, custom hubs from Bill Shook and American Classic, custom rims from one of the premier Taiwan factories where you can’t even go in the back room. Hand-laced and stressed with a custom spoke stress machine. Through three cycles. And spoke tensions measured only with a DT Swiss tensiometer. Seriously –- Rolf even specified the brand of tensiometer.

SRAM 10-Speed Drivetrain

Wide Gear Range Simply

The quest for a wider gear range usually means slapping on extra chainrings. But we take a different approach: we pair an ultra-wide SRAM 11-36T cassette with a custom FSA 55T chainring for a gear range that’s wider than using a standard 53/39T double. But because we only use a single front ring, with no front derailleur, chain lines are better, shifts are faster, weight is lower, and there are no overlapping gears.

Luggage Socket

Carry More Stuff

When you need to carry more stuff on your bike, just plug the optional Luggage Truss into the Luggage Socket that’s welded to the head tube of every Tern bike. The Luggage Truss works with any bag, basket, or rack with a KLICKfix adapter. The benefit of a frame mounted luggage system (as opposed to fork or handlebar mounted) is that it doesn’t adversely affect steering. Available Tern accessories include: Kanga Rack, Tour Bag, and CarryAll Basket.

Tern Tail Masked Paint

Super-fine Details

Getting this finish just right needed a LOT of work with our paint factory. It basically involves incredibly meticulous hand-masking to achieve the final result. With the silver/black finish, we hand-polish the aluminum frame to a mirror finish and then follow that with hand-masked black paint. Detail: the shape of a Tern’s tail is echoed in the paint masking.

"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)."

"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."

"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."
