The rear half of Tern frames use a patented 3D structure we call DoubleTruss to build in extra stiffness. It helps resist torsional forces so our bikes flex less. That means increased stiffness and much better power transfer from the pedals to the rear wheel. The proof’s in the ride.
Dropouts are often overlooked, but a good dropout goes a long way. Our Quadric dropout is built taller, so your disc brakes are protected inside the frame. The design makes the eyelets for mudguards, racks, and our clip system more user-friendly and accessible than ever before. We even included a mount for a sturdy rear kickstand.
Utilizing a single hydroformed tube mated to a precision-machined steerer, the Tarsus delivers superior strength in a shape that matches the sophisticated lines of the Verge and Eclipse frames.
The process of hydroforming aligns the grain structure and strengthens the aluminum material. It also minimizes welding in the most highly stressed area of the fork.
If you decide to equip your Tarsus with a dynamo hub, it’s ready for internal cable routing, keeping the profile of your bike clean.
Five patented technologies and unique manufacturing technology add up to the strongest, stiffest folding handlepost available. The Physis uses a special manufacturing process called 3D forging, which forms the post from a single piece of aluminum, eliminating all welds.
To eliminate flex, the Physis uses a massive joint knuckle and a post that gradually tapers from thick at the base to thin. Moreover, it has 150% more clamping height between the fork steerer and the handlepost than common designs.
The base of the Physis is machined so it functions as the upper race of the headset. This patented direct integration contributes to the incredible stiffness of the design.
Joint surfaces lock together to improve torsional stiffness. We've fine-tuned the shape to virtually eliminate squeaks.
Two bolts clamp the Physis to the fork steerer for improved safety.
The patented design puts sliding bearings between the moving parts so the folding action is always smooth and friction-free.
Large rounded surfaces are easy on your hands and provide good leverage for easy operation.
Close the lever and it automatically locks in place, for extra, easy security—using an aluminum pin.
Patented technology allows the lever to fold flat and brace against the joint for protection in transit.
Patented SpringLock technology holds the adjustment rod firmly in place so the locking lever is always properly tensioned and can never vibrate loose.
Good things are built to last and that’s why the Physis is designed to be fully dealer serviceable. We keep every part in stock and replacing the bearings can be done in minutes.
Three rubber seals keep weather out and the headset bearings functioning smoothly.
A machining tolerance of only 50 microns ensures a tight fit and eliminates looseness and rattling.
Cold-worked stainless hardware delivers the durability and reliability needed for daily riding.
The Andros is our patented adjustable stem that lets you set your handlebars where you want—no tools, no fuss. In just seconds, you can set your riding position to long and low in a tough headwind, or upright and comfy for riding around town. You decide how you want to ride and the Andros makes your bike fit.
Patented quick-release, tool-free design is easy to operate.
The Andros design uses two stems, spaced widely apart for excellent torsional stiffness.
Accommodates riders of all sizes so one bike can be shared by multiple riders.
The patented design is FEA optimized and fully forged for maximum strength with minimum weight.
Stainless hardware and brass bushings for long-term durability.
ErgoLock grips are nice and wide for excellent palm support so your hands can relax during the ride. They also lock in place on the handlebars so they’re always in the correct position, unlike non-locking grips which tend to rotate out of position.
One of our favorite ways to get a Tern bike up a set of stairs is to hook the nose of the saddle over a shoulder. It’s fast and easy, but the nose of the saddle can be hard. We solved this pain-point by re-engineering the underside of the saddle into a comfortable shoulder pad. It cushions and “grips” your shoulder so your hands are free to carry other things—like a backpack or the weekend’s groceries.
Shimano hydraulic disc brakes deliver powerful stopping power in all weather conditions with the touch of a finger.
Big Apples are special because they’re fast rolling AND super comfy. Sounds hard to believe but you’ll just have to take them for a ride to become a believer.
Wide tires roll better than skinny tires at the same tire pressure. Yes, it’s true! Big Apples are extra special because they use a light and flexible tread and sidewall for extra low rolling resistance.
Super-wide Big Apple tires are like 2" of super-efficient suspension. They roll smoothly over drainage grates, train tracks and potholes with little complaint.
Big Apples feature a Kevlar belt to protect from punctures.
Each Big Apple tire features a reflective stripe so you are immediately, and obviously, visible to cars approaching from the side.
The Magnetix 2.0 uses powerful magnets to keep your bike folded for situations like carrying your bike up and down stairs. With a pull force 10-15 Kgf, the Magnetix 2.0 will keep your bike folded even when being jostled and moved about.
Fix the Tern Luggage Truss to the Luggage Socket and you can plug in your choice of front luggage: rack, basket, or bag. If it’s KlickFix compatible, it’ll work.
You need to be safe when you’re out on the road. That’s why we’ve designed our hard-core commuter bikes with 720° Visibility: 360° of active lighting and 360° of reflectivity.
Specially designed lights allow you to be seen from all angles when it’s dark out. Accidents often occur at 90° angles at an intersection so active side lighting is especially important.
Bright car headlights can overwhelm the active lights on a bike and this is why reflectivity is important: the brighter a car’s headlights, the brighter the reflective patches shining back at the driver. Bikes with 360° Reflectivity are visible from every angle to oncoming cars.
