Adams' Original Shifter 7 Trail-A-Bike lets your child pedal along with you and enjoy the ride. Easy to pull and pedal, it has a steel frame, a 20-inch wheel and boasts a 7-speed drivetrain so they can shift with you to cruise over the ups and downs. With a sturdy steel hitch that connects to most seatposts (four shims are included), it fits on most bicycles with 26-inch and 700c wheels. The kid-size pedals, grips, seat and adjustable stem allow them to ride in comfort and style, and there's even a fender for rain and mud, and a bashguard for drivetrain protection. Plus, you get a high flag for visibility and safety, and this trailer folds quickly for convenient storage and transport.
