Folding Bicycle Description
Be nimble… be quick… be Jack! The Jack is designed to go at any pace you choose and to roll over anything in its path. Forget leaving your urban machine in that communal bike garage and getting nicked and scratched; keep it inside and safe… with you. That’s how it should be, right? Jack is designed around a beefy 7005 aluminum frame and phat Schwalbe Big Apple tires. The Jack has seven nicely-spaced speeds to keep things simple, but that’s enough gears for most anything you’re likely to encounter in the city. What kind of bike is this? It’s a human powered urban machine, Jack.
Technology Highlights
  • Fold it and store it in your trunk so you save the cost and hassle of a car rack.

  • Folds in less than five seconds so you can take it anywhere.
  • Easy to fold and fun to ride.
  • Schwalbe Big Apple tires are luxuriously comfortable, fast rolling, and have a Kevlar anti-puncture lining.

dahon reviews

"The Dahon Jack 26 in-wheeled folder is a solid urban and trail runabout with a nice clean feel to it. Most notably though, it's that rarity, a larger-wheeled folder. This means handling stability is preserved – an important point for those who shy away from smaller wheeled folders because of their more sensitive ride qualities."

"The Jack itself is a lovely bike for cross town jaunts, dropping off kerbs and soaking up potholes with its Schwalbe Big Apple tyres. If you don’t need the motor or run out of power it’s still a great bike to ride with that free running motor."
