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 handle post 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.
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.
Stronger, Stiffer, Better Ride
Flexy handleposts and noodly handling are the Achilles heel of many folding bicycle designs. The Physis handle post solves this with a massively strong, precision machined design that virtually eliminates flex. Four new patented technologies go into the design. The proof, of course, is in the ride.
Massive Strength — To eliminate flex, the Physis Joint knuckle was beefed up and made wider by moving the pivoting surfaces outward from the centre axis.
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 drive train. Hub gears have a number of benefits: with the gears all protected inside the rear hub shell, hub gears require almost no maintenance; they 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.
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 chain guards and enjoy the looks and cleanliness of a belt drive with the efficiency of a chain drive.
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.
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. The Portage 24 rack is also designed to work with mid-sized pannier bags. 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 STEALTHY ONE
Why not trade $4.00 gas, monthly insurance, parking fees, and traffic jams for a stealthy cool Link bicycle, daily workouts, and a car-sharing service? The Link D7i is perfect for getting around in the city; for longer trips, just fold it and jump on the nearest subway or bus line. And Costco runs — that’s what ZipCar or your friend’s car is for.
