Using this bag is super easy. First, adjust the Velcro straps to fit your bike's handlebars and stem. Then, attach the bottom strap with the Duraflex buckle to the fork crown. You can put a standard cycling bottle, some snacks, or small essentials inside. When you're done using it, just detach it from the bike. As for maintenance, you can wipe it clean with a damp cloth. Avoid using harsh chemicals as they may damage the Nylon Robic material. Store it in a dry place when not in use. Remember, the bottle isn't included, so you'll need to provide your own.
