Eclipse P7i

The Fully-equipped

27% of all trips in the Netherlands are made on a bicycle and that’s why Dutch bikes are true utility machines that handle everything from shopping to sending the kids to school. The Eclipse is the same kind of bike — with lights, racks, and fenders all integrated — but with the extra convenience of portability, so when needed it’ll origami down small to fit on a bus or in your hallway closet.

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.

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.

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.

Andros Stem

Adjust to Fit

Your bike should adapt to your body and riding style, not the other way around. That’s why we developed the Andros, an adjustable stem that not only adjusts for height, but also reach. So whether you want your bars high and far, or low and close, the Andros will adapt. A single quick release controls both the stem and handlebar so it takes only seconds to get the bars in the position you want. The Andros features a patented TwinStem design, making it extra stiff and strong.

BioLogic Arx Grips with T-Tool

Be Prepared

You know the feeling: you’re on a ride and you need to adjust something and discover that you’ve left your bike tool at home. BioLogic figured that if the most handy tools could be stashed on the bike someplace, it would be one less thing to worry about. So they designed the T-Tool – a special bar end plug and hex key tool that fit right inside the handlebar grip – invisible but always there when you need it. The patented T-Tool features 4 mm, 5 mm, and 6 mm hex keys built into one handy unit with a long leverage design for the 5 mm and 6 mm tools.

BioLogic PostPump 2.0

Always Ready for Pump Action

If you’ve ever used a traditional bicycle mini-pump, you’ve probably scraped some knuckles or ripped a valve and uttered a few choice phrases while you blew out your arms. That’s why we love the BioLogic PostPump, a full-size floor pump that’s hidden inside a seatpost. It pumps a much higher volume of air and the pumping action is easy, just like a floor pump, because you are using your whole body. And because it’s hidden in the seatpost, it’s always ready when you need it. The completely re-designed 2.0 version is slick and has an integrated Schrader and Presta adapter.

BioLogic Joule 3 Dynamo Hub

Super Light, Super Efficient

The Joule 3 is the lightest, smallest dynamo hub on the market and is one of only a handful that exceed the High Efficiency (HE) 70% threshold. Most other dynamo hubs have much lower efficiency; the lower the efficiency, the more drag you feel when you’re riding. The Joule 3 is so efficient, that you’ll hardly notice it’s there, even as you’re using it to power your lights or charge your phone. Best of all, with the Joule 3 you’ll always have power when you need it and you’ll never have to toss out a light battery again.

Shimano Nexus 7 Drivetrain

Durable, Low Maintenance

In countries where bicycles are a primary mode of transportation –- the Netherlands, Germany, Denmark –- hub gears have always been the default choice of drivetrain. Hub gears have a number of benefits: with the gears all protected inside the rear hub shell, hub gears require almost no maintenance; they are much easier to keep properly adjusted; and you can shift from a standstill –- perfect after you’ve stopped for a red light. The Shimano Nexus 7 is one of the best hubs on the market –- 7 speeds are perfect for just about any kind of city riding and the shifting is super smooth.

BioLogic FreeDrive

Clean and Quiet

The BioLogic FreeDrive encloses the bicycle chain to keep the rider’s clothing protected from grease and dirty spray. The FreeDrive’s ingenious design moves with the chain so it is friction free, unlike with some other chain protection methods. It also reduces chain vibration and noise. With a FreeDrive, you can say goodbye to bulky chainguards and enjoy the looks and cleanliness of a belt drive with the efficiency of a chain drive.

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.

Valo 2

Engineered to integrate directly with the Andros stem or the Syntace VRO 47 stem used on many Tern bicycles, the Valo 2 is a powerful hub-dynamo powered light designed to help you navigate safely at night. It is optimally positioned for visibility and well protected from accidental knocks and bumps, as well as theft. Clarity™ optics projects the type of wide, even beam pattern that a cyclist needs - no more lighting the tops of trees in the distance or narrowly focused hotspots.

BioLogic Portage Racks

Carry Your Stuff

Running errands, shopping –- when you do these things by bike, you need to carry stuff. Portage racks are custom-designed for Tern bikes to help you carry your stuff, in lots of different ways. From the factory, Portage racks come with an elastic luggage strap that’ll keep even bulky items strapped safely to the top of the rack. Best of all, Portage racks are KLICKfix-compatible so all the bags out there with KLICKfix attachments, including the BioLogic Commute Bag, can be clicked on and off in seconds.

"The Eclipse P7i is easily a very good contender for a practical bike. We at Headset Press really like the look of Tern’s, coming in good colours and generally well styled (not common for folding bikes!). They pay a lot of attention to the aesthetic of their bikes and it really shows. So if you’re in the market for a folder or solid commuter bike look no further than Tern."

"Overall, the Tern Eclipse P9 folding bicycle rides like a dream on the street, with the 24” wheels rolling over the bumps and crevices with ease. With its range of gears you’ll be able to ride up bridges and hills during your commute, or carry some groceries home from the store. At the end of your ride, fold up the bike and stow it away. The Tern Eclipse is a great blend of comfort and portability."

"And when it comes to handling, the Eclipse S11i is on a class of its own. The bike’s Andros steering system is solid and responsive. I tried the bike on three different kinds of riding: short and middle distance commutes, long-distance day tour – and I am happy to report that all had turned out really smooth."

"Das Tern ist die eierlegende Wollmilchsau, die sich wirklich fährt wie ein großes Rad. Größere Laufräder und ein etwas größeres Faltmaß bringen beim Tern ein vielfaches an Fahrfreude an einem rundum gelungenen Rad. RADtouren Kauftipp!"

June 27, 2012

"Was die Eclipse-Serie von Tern auszeichnet, ist unseres Erachtens vor allem das Fahrverhalten: Die um zehn Zentimeter größeren Durchmesser im Vergleich zu den üblichen 20 Zoll-Rädern stabilisieren durch ihre höheren Kreiselkräfte die Fahrt, sie loten mit ihrem größeren Radius nicht jede Plattenfuge aus, und sie verkürzen Dank des höheren Rahmens den Überstand von Sattelstütze und Lenksäule. Diese werden dadurch wesentlich steifer. Zudem hat Tern gegenüber früheren Dahon-Modellen die Rahmen komplett überarbeitet und mit deutlich größeren Faltscharnieren versehen. Wiegetritt, einhändiges oder gar freihändiges Fahren – unterm Strich fährt sich das Eclipse P9 fast so, als sei es kein Faltrad."

"The Tern’s larger wheels and stout frame take it in stride, and feel quite comfortable at speed, too. The double-braced, fully adjustable stem, in particular, gave this bike the most assured front-end stiffness of the bunch — plus it’s a great feature for fitting riders of varying sizes."

"The Tern Eclipse S11i is one of the most well conceived folding bicycles from Tern. It has more features than any other Tern bike: dynamo lights, hydraulic disc brakes, rack, fenders, adjustable handlebar, and the list goes on! If you want the best of the best folding bikes from Tern the Eclipse S11i is the one for you."

"So you got a folding bike, you can just go in (to the ferry) and sit down. So while everybody kinda has their bikes deck on each other. You can just hang out and have your bike next to you for the next ride. This is pretty cool."
