Redline Roam 20" Kids Bike. The Redline Roam has race-inspired geometry, a high-tensile steel frame, and taller handlebars for easy maneuverability. The Roam features a freewheel for those looking to graduate from coaster brakes. Sporty racer graphics add some style, while 20 inch alloy rust-resistant wheels keep this bike in good shape through all the seasons. For kids ready to ride with hand brakes on the sidewalk, the bike path, or at the park, the Roam will open up a path to new adventures.
