This dog bike trailer converts into a pet stroller in seconds, giving you one piece of gear for both bike rides and daily walks. The 31.5 x 21 x 22-inch cabin comfortably fits medium to large dogs up to an 88-pound weight limit, with enough room to lie down or turn around, and a rear door for easy entry and exit. A clear PVC flap up front keeps wind and rain out while mesh panels on the sides keep air moving and let your dog watch the world go by. A built-in leash clips inside to keep your pet secure whether you're towing it behind a bike or pushing it as a stroller. The reinforced steel frame and rear reflector with safety flag add durability and visibility for road use. The universal coupler attaches to bikes with 22 to 28-inch rear wheels, and the frame folds down to 31.5 x 24.4 x 9.4 inches for compact storage in a trunk or closet. At 32.2 pounds, it's manageable to carry folded between uses, and switching from trailer mode to stroller mode takes only moments.
