Weehoo's iGo 2 Trailer Bike lets both of your little ones come along on rides! And, its single-wheel design means you can take it anywhere your bicycle can go (since the iGo is as narrow as a standard bike). This iGo also allows one kiddo to help out with the pedaling, while the second child sits back, relaxes, and offers words of encouragement. It boasts a sturdy high-tensile-steel frame, a lightweight, easy-rolling aluminum 20-inch wheel and comfortable quick-adjust seats with aluminum frames so your child can easily reach the pedals and/or footrests (pedal straps ensure their feet won't slip). They'll especially love the amply padded bucket seats with built-in hand grips. And you'll love the 3-point safety harnesses for security and peace of mind. There's also an enclosed drivetrain to keep their fingers and pants safe and clean. Plus, for easy on/off and excellent durability the iGo has a weld-free bike hitch. Other handy features include rear panniers and a seat bag for impressive carrying capacity and reflective details and a flag for visibility.
