OCL™ Frame Joint
Advanced folding technology
The key to any folding bicycle is the frame, and specifically, the folding joint at the heart of the frame. Done well, it locks the two halves of the frame together without any hint of movement or sound. It should be easy to operate and work flawlessly year after year. The OCL Joint does all of these things and is a new reference in folding frame technology.
Physis™ 3D Handlepost
The new benchmark
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.
Adjust to fit
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.
BioLogic PostPump™ 2.0 Seatpost
You’ll always be prepared with this high-capacity floor pump hidden inside your seatpost. A true floor pump, it delivers a much higher volume of air than traditional mini-pumps, and the pumping action is easy—great for those high pressure or large volume tires.
BioLogic Joule™ 3 Dynamo Hub
Make your own juice
A hub dynamo is the ultimate green power source because it generates electricity while you ride—no batteries or recharging required. The Joule 3 is one of the very lightest and smallest dynamo hubs on the market and is one of only a handful that exceeds the High Efficiency (HE) 70% threshold. Say goodbye to batteries. Winner of a Eurobike award, the Joule 3 meets German StVZO standards for a 6V/3W hub—meaning it can power both a front and rear light.
Valo™ 2 Light
Floodlights for your ride
The Valo 2 is a powerful light designed to help you navigate safely at night. The unique design integrates directly into the handlebars of an Andros or VRO-equipped Tern bicycle so it’s protected from theft and damage. And because it’s hub-dynamo powered, you never need to worry about batteries or charging again. Flick a switch and you have instant light.
Load ’er up
The Cargo Rack is designed to get stuff off your back and onto your bike so you can enjoy the ride. It is outrageously stiff and chock full of smart details that make it better than anything else we’ve used for hauling large loads. Optimized for the unique geometry of Tern bicycles.
