Built for medium to large dogs, this bike trailer offers a 31.9 x 21.9 x 25.2-inch cabin with enough room for a dog to lie down or turn around comfortably during the ride, up to a 100-pound weight limit. The universal coupler attaches quickly and securely to bikes with 22 to 28-inch rear wheels, and a rear door makes getting your dog in and out simple. Up front, a clear PVC flap blocks wind and rain while mesh side panels keep air flowing and let your dog see out, so they stay dry, cool, and calm on the road. A built-in leash clips inside the cabin to keep your dog secure, and a rear reflector along with a safety flag improve visibility for other riders and drivers. The reinforced steel frame holds up to daily use, and the whole trailer folds down from its 53.1 x 28.3 x 33.1-inch riding size to a compact 31.2 x 24 x 8.1 inches, with detachable wheels, for easy storage in a car trunk or closet between trips. Net weight is 26.5 pounds.
