I converted this "InStep Rocket" into a pet-friendly utility bicycle trailer. Very useful for hauling camping gear on bike trips, or for taking along you pet for an outing. When you arrive at your destination, the trailer detaches from your bicycle to become a convenient stroller. Universal coupler attaches quickly and easily to bikes. Used, but in good condition. Below are some of the specifications... * Stroller wheel and push bar make this great for walking or running * 20" fast rolling alloy wheels with quick release design for easy storage * Quickly converts to a stroller without using tools * Lightweight aluminum frame design * Custom 21" by 31" (removable) wooden platform * Universal coupler attaches quickly and easily to bikes * Canopy offers transparent, drop-down & weather shield * Can be used with or without the Canopy * Hold up to 100 lbs of cargo * Folds flat for storage * Dimensions: 31" x 35" x 33" * Folded Dimensions: 31" x 35" x 20"
