  • Getting quickly around campus
  • Bar hopping (eco style)
  • Flying through the city with the greatest of ease

The Jack is designed to go at any pace you choose and to roll over anything in your 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? The Jack is designed around a beefy 7005 aluminum frame and phat Schwalbe Big Apple tires. The Jack has seven nicely-spaced gears to keep things simple, enough 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.
