Don't worry about carrying a heavy, hot backpack or awkward purse while biking! If you want to ride with work files, groceries, or swimwear to the beach, then a saddlebag is your best choice.
Bike bags can sit almost anywhere on your bike, from your handlebars to your seat post to your rear rack. A handlebar bag can carry maps, tools, and phones while out biking. Pannier bags attach to the rear of the bike, which may be where your battery sits. Covering your rack with a bag provides extra storage when you're out and keeps your battery safe from dirt and debris.
