Heavy-duty dog bike trailer hauls pets up to 66 lbs in a fully enclosed pet compartment that measures 30 x 21 x 20.8 in. The carbon steel frame folds in seconds for storage and a universal coupler links the trailer to bicycles with 22 to 28 in wheels. 600D Oxford fabric panels resist water and sun while reflectors and a high-visibility flag keep the trailer noticeable in traffic. Quick-release wheels pop off for tighter storage and the cabin opens through a top zipper for easy pet entry.
