Think of this bike as a personal trainer and a limousine all wrapped into one. Get in shape, get to work, or just have fun, Cannondale's Quick 6 features a light, efficient aluminum frame that effortlessly zips down the road. It offers plenty of comfort, too, thanks to the upright riding position and curved rear frame that flexes ever so slightly for a smooth ride. What's more, it boasts easy-rolling 700c wheels and a Shimano 21-speed drivetrain with all the right gears for the ups and downs. The Quick also sports powerful linear-pull brakes, lightweight Cannondale aluminum components, a plush seat and reliable Kenda tires.
