Joe D24 | Tern Folding Bicycles

For the Road Less Repaired

Skinny tires are for going fast on smooth, well-paved roads. The roads you ride? Not so much; and that’s why we use burly Big Apple tires with puncture protection. Paired with strong wheels and a stiff frame, you have the ideal townie. But you also have the freedom to jump on a bus or train with a five-second fold.

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.

FBL Frame Joint

Strong and Secure

The FBL (Four-Bar Linkage) Joint is a tried and true design that keeps a frame securely locked. It features a forged and precision machined lever designed to offer a smooth surface for fingers. All other hardware is stainless steel for durability.

DoubleTruss

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.

NVO Axis Stem

Adjusts to Fit You

Every rider has a unique combination of body shape and riding position that feels most comfortable. That’s why a bike that adapts to the rider is so important. The Axis stem delivers an incredible range of height and reach adjustment. For storage, the Axis stem can be rotated 90 degrees for even more compact storage options. And the tool for making all of these adjustments? Stashed in your right handlebar grip.

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.

Schwalbe Big Apple Tires

Big and Cushy

There’s an unfortunate misconception that wide, large volume tires are slow and inefficient. We were guilty of this ourselves the first time our Swiss and German product guys recommended we try the Big Apple’s. But then we rode the tires and fell in love. As you might expect, the Big Apple’s are super plush and give a great feeling of security on streets where potholes, train tracks, and drainage gates are the norm. But they are also surprisingly fast and easy rolling. Integrated puncture protection and reflective sidewalls add to urban functionality.

Tern Joe D24 Review

November 3, 2011

"Now the last folding bike that I rode had a “squishy” feeling to it – the frame wasn’t super sturdy, and tended to flex on big bumps. That’s not a problem with the Joe D24 though, because Tern has gone out of their way to make sure that the frame here is completely solid."
