Handlebar bags give you the possibility to conveniently store and access stuff easily within reach of the riding position. Handlebar bags either fasten with a mounting system or use straps and velcro. They're ideal for holding a camera, snacks, your wallet and mobile phone. Another type of handlebar bag is the "handlebar roll", which is particularly popular for bikepacking. These are attached to the handlebars with straps to ensure they stay put even on mtb trails. As with all bike bags, it's a good idea to check if the bag is waterproof before buying.
