Joe C21

The Easy Cruiser

Living in the city means staying flexible and adapting to change. That’s why transportation that adapts to your itinerary is the way to go. Smooth Sunday cruise? Check. Friday night ride down to the pub? Check. Cutie from the office offering a ride home on a rainy day? Check.

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.

DoubleTruss

3-D = Stronger

Folding bikes have a sometimes deserved reputation for flexy frames.

That equals increased stiffness and much better power transfer from the pedals to the rear wheel.

"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."
