Technology

OCL+™ Frame Joint

A heavy-duty update to our iconic OCL frame hinge, the OCL+ is built to exceed ISO 4210 and EN 15194 testing requirements. Leveraging the hinge design of the long-tail Tern Cargo Node, the OCL+ features a single-shaft design, advanced welding techniques, and robust gussets, so it stays stiff and strong during even the fastest commutes.

DoubleTruss™ Technology

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.

Quadric™ Dropouts

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.

Tarsus™ Fork

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.

Physis™ 3D Handlepost

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.

Andros™ Stem

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.

Porter+™ Saddle

We reengineered the underside of the age-old bike saddle into a comfortable grip and shoulder pad. Up top, the dual-density construction and gel cushioning will keep you comfortable on the road, and the impeccably finished vacuum construction makes the saddle waterproof and easy-to-clean. Down below, the GripPad™ on the underside of the saddle lets you grip the saddle nose with comfortable confidence when your rolling your folded bike.

Telescopic Seatpost™

This seatpost is perfect for tall riders or anyone who likes a compact fold. It extends 90 mm longer than our stock seatpost, but thanks to its unique design, it’s 120 mm shorter when retracted. It features a dual-bolt head design for precise saddle adjustment, and an inner post diameter of 27.2 mm, so you can customize it with other posts.

Magura MT4 Hydraulic Disc Brakes

Hydraulic disc brakes give you excellent stopping power, working effortlessly even in rain, snow, or mud. All it takes is the gentle pull of just two fingers. With mineral oil-based brake fluid that is gentler on the environment than most hydraulic brake fluids, and Magura's Easy Bleed Technology, your Vektron is ready for a safer ride.

Schwalbe Big Apple Tyres

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.

Shimano Deore Shadow+ Derailleur

Originally developed for mountain bikes—for extra durability and to avoid catching on trail debris—the Shadow+ derailleur is streamlined and incredibly resilient, which comes in handy when you need to transport your folded bike. Whether your bike is bagged on the subway or riding in the trunk of your car, everything is neatly tucked away. And with a clutch to adjust the chain tension, you can now ride on bumpy city roads without worrying about chain drops.

Bosch Performance Drive Unit

Electric bikes make it easy to ride from A to B. Where it gets interesting? When you’re inspired to visit the rest of the alphabet. The Bosch Performance Drive Unit offers a fine-tuned balance between torque and range. It takes the burden out of hauling kids and groceries. With up to 100 km of range with a standard 400 Wh battery, it’s the market leader in ebike technology.

Bosch PowerPack Battery

This impressive high-energy, high-power cell clips on and off your bike. The best-in-class design charges fast—from zero—in only 2.5 to 3.5 hours, and lets you ride longer and further between charges. You’ll be impressed by its long lifespan, light weight, and ease of charging. PowerPacks are available in 300/400/500 Wh variants, so you can forget about range anxiety.

Bosch Purion Control Panel

The on-board computer lets you switch between five different riding modes, and feeds you handy information like speed, battery level, and distance. It optimizes shifting actions and constantly updates you on the remaining range, just like a typical German car. Best of all, it’s now more compact and robust than ever.

Luggage Socket™

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.

720° Visibility

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.

Atlas V Rack™

With structural cues from the heavy-duty Tern GSD, the new Atlas V Rack™ has been massively strengthened and increased in size, with a load capacity of 27 kg (59 lb). This reduces flex for more secure handling when the bike is loaded. Riding with your little one? Add a Thule Yepp Maxi or Dash® RM child seat—no adapters needed. The Atlas V Rack™ is also KLICKfix-compatible, and can hold panniers of different sizes—including the Bucketload Pannier, which was designed to fit every configuration of the Vektron.
