The Allen Sports ET2 2-Child bicycle trailer offers the perfect outdoor solution for active parents. The item quickly sets up as a bike trailer right out of the box. 16″ rear wheels deliver low rolling resistance, and large front and side windows let your passenger enjoy the ride. The trailer includes a foot bar that protects your children’s feet, and also comes with a removable three season bug and rain shield. The five-point safety harness securely holds your children in place during use. A universal coupler secures to your bicycle’s rear axle and makes installation and removal from your bicycle a snap. The trailer also includes a safety flag for added visibility when riding. All Allen trailers pass the ASTM trailer safety standards.
