There are always more reasons not to exercise than to actually do it, and when it comes to getting a ride in, one of the most common complaints that we hear is about how tough it is in the city. If this sounds familiar, we have the solution to your problem—the Roll City. It's custom-built to tackle the urban landscape, with features like wide, reflective tires, powerful Shimano hydraulic disc brakes that stop on a dime, a tough, durable frame, and mounts for racks and fenders. We even gave it a unique reflective paint job that illuminates in order to increase your visibility to motorists in low-light conditions. This way, you can turn any ride into a workout and every workout will feel just like an awesome, comfortable ride.
