They say that every journey begins with a single step, but when that journey is related to exercise, that first step can sure be a doozy. It can be life-changing, however, and there's no better machine to take the plunge with than with the Roll. The 2021 Specialized Roll Sport Step Thru Comfort Bike has everything you need to help achieve your goals, like a wide range of Shimano gears, a comfortable, upright geometry, wide and grippy 650b tires, hassle-free mechanical disc brakes, and a whole host of other components that are built to withstand years of riding. You don't have to sacrifice—you just need the Roll Sport.

The Low-Entry Roll is made of A1 Premium Aluminum. It features Ground Control Positioning that makes it easy to put a foot down when stopped, while our Low-Entry design makes getting on and off a breeze. Lastly, the frame comes ready with rack/fender mounts.
Wide diameter, 650b x 2.3" Nimbus II Sport tires provide excellent traction, stability, and cushioning, which creates a safer, more reliable, and more comfortable ride on either paved or dirt roads. Plus, the reflective accents of the tire increase your visibility to motorists in low-light conditions.
Equipped with our Body Geometry "The Cup" saddle, you can expect a supreme level of comfort anywhere you take the Roll. It delivers on these expectations by "cupping" your sit bones, which reduces pressure without feeling obtrusive or constraining.
