Owners who switch between cycling and walking get one cart for both. This 2 in 1 trailer and stroller cart supports dogs up to 100 lbs in a 31.5 by 21.2 by 24 in cabin built from carbon steel and 600D Oxford fabric. Hitch the cart to a bicycle for park loops then snap on the front wheel and walk the same dog through trails or city sidewalks. An internal leash clip keeps pets anchored, quick-release wheels remove for trunk transit, and the frame folds to 30.7 by 24.2 by 9.4 in.
