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, 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 only 7 speeds to keep things simple, but 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.
