The PUBLIC C7 is our most popular, lightweight, affordable multi-gear bike. The easy-shifting, 7-speed city bike with external derailleur gears takes you virtually anywhere and back, even up and down the toughest hills of San Francisco. With its curved, open, step-through frame design, it is often referred to as a Dutch bike. Its a time tested classic bike design seen commonly throughout Europe for decades. (For safe riding, PUBLIC Bikes on Amazon require bike shop assembly by a professional bike mechanic).
