This is a black storage and protective bag for MOBIC folding bicycles. It is a new, unused item. I unfolded it for measurements and photos. (The first and second photos are from the MOBIC website.) I bought it for storing a Brompton, but I never used it. The unfolded size is approximately 85 x 80 x 35 cm. There are adjustment belts on both sides. A storage bag is included. It doesn't fully cover the bike, so it might be difficult to use for train travel as is, but it can be used for storage or when putting the bike in a car. Although it is unused, there are wrinkles from storage, and it is not new as it has been handled by a person. Please understand this, and those who can agree to no returns, no cancellations, and no refunds, please consider purchasing. I am a non-smoker, but I have a small dog in a separate room from the storage area. Please refrain from purchasing if you are concerned about this. The following is a quote from the MOBIC website: --- The MOBIC folding bike bag is made of durable, thick nylon (not thin nylon) and is padded to protect your MOBIC folding bike during transport. It neatly fits into a small backpack with adjustable drawstrings. It's perfect for folding and carrying your MOBIC. You can carry it on your arm or shoulder. It fits all MOBIC folding bike models and folding bikes with 13-inch, 16-inch, 18-inch, and 20-inch wheels. The internal dimensions are 32 inches x 17 inches x 13 inches. The bag is flexible, so it will fit folding bikes that are 1-2 inches larger than these dimensions. The dimensions when folded into the backpack are 18 inches x 10 inches x 2 inches. #HalloweenOnMercari
