Adams' Original Alloy Folder 1 Trail-A-Bike lets your child pedal along with you and enjoy the ride. It's crafted of lightweight aluminum and has a 20-inch wheel, so it's super-easy to pull and pedal. 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.
