Diamondback's Serene Deluxe is a perfect choice for more comfort and fun whether you pedal for pleasure, fitness or to get around town. This smooth, versatile ride features a lightweight, step-through aluminum frame with a suspension fork for soaking up the bumps. You'll love the stable 26-inch aluminum wheels and the precise 21-speed Shimano drivetrain to help you zoom up the hills. Grippy linear-pull brakes provide plenty of stopping power, and for unbeatable comfort, you have well-cushioned Selle Royal seat with a suspension seat post.
