From its folded, round state, it can be unfolded like a tent, and then secured to the left and right of the front handlebars with Velcro, allowing it to be used simply by carrying it like a backpack. - Brand: Bub-up (German manufacturer, purchased this year from a Spanish website) - Folding method: Yes (with round instruction manual in the photo) - Color: Blue/Yellow - Size: Circular - Usage: Rain cover for vehicles with handlebars such as bicycles (electric bicycles, scooters, kickboards, etc.). When unfolded, the length is approximately 100+ cm (see photo), when folded, the diameter is approximately 44cm, the thickness is about 6-7cm, and the weight is about 1.2kg. I tried it twice on rainy days with a bicycle. Indeed, it kept most of my upper body dry, but for someone like me, who makes deliveries and gets on and off the bike frequently like a mail carrier, the process of repeatedly taking it on and off like a backpack was cumbersome, so I've decided to sell it. It seems effective for continuous travel from point A to point B, or for a round trip. It's also good to carry it folded up and be prepared for sudden rain. It has a solid construction, typical of a German manufacturer. Please consider it, referring to the photos and the description. (Shipping usually takes 1-2 days on weekdays)
