Swoop Duo

The Local One

Hop on and ride. Hop off when something catches your eye. It feels like an old friend you just met. Footloose and fancy free, the Swoop Duo makes it look easy with cable-free, 2-speed automatic shifting and a super low-step design.

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.

Low-Step Design

Hop on and off with ease

A low-step design allows you to get on and off the bike easily, which is great for those who have difficulty getting on or off a bike, or for those who haven’t been on one in a while. It’s also great for people who like to ride in either tight jeans or skirts. The top tube is only 28 cm (11”) off the ground, making it one of the lowest on the market. The low center of gravity of the design also enhances stability, which less-experienced cyclists will appreciate.

Scuff Guard

Chainguard protection

The scuff guard protects the chainguard from bumps and knocks while keeping your feet and clothing clear of the chainring. It’s also a convenient handle for picking up and carrying the bike when folded.

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 piece 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.

SRAM Automatix 2-speed Drivetrain

Simply Innovative

This is innovation. The Automatix is a 2-speed drivetrain that shifts automatically. No shifters, no cables. It detects your speed and shifts when you need it. First gear is for getting started and going up small hills, and second gear is for fast riding on the flats.

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.

Detachable Rear Rack

Load 'er up, or take it off

Racks are great. They can carry tons of stuff while leaving you free and unencumbered to enjoy your ride. Sometimes, though, you might want to leave the rack off either for weight savings or for looks and that’s where a detachable rack comes in. Take it off when you don’t want it, or put it on when you need to haul some stuff. Three hex screws securely anchor the rack to the frame. The best thing is it looks like it’s just part of the bike and not an add-on.

Tern Swoop: a Commute-Ready Folder

December 9, 2012

"The bike felt comfortable and relaxed, not unlike a full sized European city bike. The fat tires drowned out bumps very nicely. Unlike some of the other non-Brompton folding bikes I've tried, the Tern Swoop felt pleasantly un-flimsy. I did not sense any play in the fold joints, nor did I feel flex in the frame while cycling. The ride quality was stable and novice-friendly."
