Smaller pet bike trailer hauls small to medium dogs up to 66 lbs in an enclosed cabin that measures 26 x 16.9 x 19.3 in. The carbon steel frame folds for storage and a universal coupler attaches the trailer to bicycles with 22 to 28 in wheels. 600D Oxford fabric panels resist water and sun while an internal leash keeps pets clipped securely during the ride. Reflectors and a high-visibility flag improve visibility in traffic and quick-release wheels detach for tighter trunk storage.
