This is a large bag from Captain Stag. I used it several times as a bike travel bag. I put a 16-inch folding bicycle in it. It has an adjustable shoulder belt. There are holes in it from when I put the bicycle in. See photos 5, 6, and 7 for reference. The size is 50cm high, 36cm wide, and 80cm long. Please note that these are amateur measurements, so there may be some slight errors. Thank you.
