The aluminum Allen Sports bike trailer is a fully functional two-child, fixed wheel jogger that quickly converts to a two-child bicycle trailer. Its extra-large passenger compartment keeps your riders comfortable, and a footguard tube protects your child's feet. Large front and side windows let your passengers enjoy the ride, and the three-season cover includes a bug screen. Integrated zippers secure the bug and rain screen in place. The universal coupler attaches to most bicycles. The aluminum Allen Sports bike trailer has a folding design with quick-release wheels, which makes for easy transport and storage.
