All aboard the fun train! Adams' Folding Tandem Trail-A-Bike lets your children 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 the front child 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 youth-size pedals, grips and seats allow your kiddos to ride in comfort and style, a bashguard provides drivetrain protection, and both handlebars are adjustable for a perfect fit. Plus, you get a high flag for visibility and safety, and this trailer folds quickly for convenient storage and transport.
