I purchased this for a Boardwalk D7, but I'm selling it because I sold the main unit. The following is a quote: This is a rinko bag compatible with many major railway companies, including the JR Group. This dedicated rinko bag is convenient for rinko (taking it on public transportation) and indoor storage. It covers the entire body of the bicycle and closes with a zipper, so tires and seat posts won't stick out of the bag. When not in use, it can be folded compactly and attached to the seat post or handlebar. We offer four types depending on the bicycle size. Slip Bag 20" Compatible with 20-inch models (excluding the Dash series), Compact Size: W230 × H140 × D50mm, with shoulder strap
