Jamis Started out by making cruisers. The Boss cruiser. 30 plus years later, the bike is still around, almost unchanged. Jamis Cruisers are made with a purpose. Make a cruiser that rides great without the traditional things that would make a bike clunky. Lightweight aluminum frames, no fenders,and powder coated parts make these bikes ride great while keeping maintenance down. Choose from no gears or 7 gears with the Boss Cruiser. Choose from no gears or 3 gears with the Earth Cruiser.
