Under-saddle bike bags are a great way to store your belongings while cycling. They can hold all the essentials, such as cell phone, wallet, keys or a bottle. They come in several capacities: from 0.6 liters to as much as 12 liters. Thanks to the fact that the bike bags are fixed under the saddle, they do not interfere with the ride and, what is most important, they are stable on the bike.
