The Beautiful Green Bikes have 3 gears, a very upright riding position, a front brake on the handlebars and a pedal back brake - think classic Cruiser for short rides up and down the waterfront.
The Handsome Black Bikes have a slightly less upright riding position, but are still feel very casual - you won't feel like you are riding in the Tour de France. These bikes have been designed for pathway riding, so are perfect if you are going for two hours or more. They have 24 gears, disc brakes on the handlebars, and seat and fork suspension for extra comfort.
