Designed for active owners with medium and large dogs, this 2 in 1 cart switches from bicycle trailer to pet stroller in minutes. The carbon steel frame supports up to 88 lbs while the 31.5 by 21 by 20.8 in pet cabin offers room to sit or curl up on long rides. A universal coupler hooks the trailer to most 22 to 28 in wheel bikes, quick-release wheels make folding fast, and reflectors plus a high-visibility flag keep the cart noticeable on streets and trails.
