It features a spacious cabin with mesh ventilation panels, a clear PVC front flap for weather protection, and a built-in leash for added safety. The reinforced steel frame provides stable towing, while the foldable design and quick-release wheels make storage and transport easy. A universal coupler fits most adult bikes with 22"-28" rear wheels for convenient attachment.
