Engineered around a powder-coated carbon steel frame this dog bike trailer hauls pets up to 100 lb behind any 22 to 28 in wheel bicycle. The 31.9 x 22 x 24.4 in pet compartment fits two medium pets with room to lounge while a 600D Oxford fabric shell blocks rain wind and Uv rays. Quick-release wheels and a folding frame compress the trailer to 31.89 x 22.44 x 7.68 in for trunk storage. A zippered front door mesh canopy and rear ventilation port keep airflow strong on every ride.
