The Senhor Prudencio Bicycle Case from Wrong Weather is a briefcase designed specifically for bike riders. You attach it to the bicycle frame using the zip and buckle system, and it fits snugly into the empty triangle created by the frame. The arrangement works perfectly for most standard bike sizes, unless you’re a Lilliputian driving a very small or very large bike. Afterwards, you may easily remove the bag from the bike and use it as an ordinary bag when you’re not riding the bike. It has a velvety lining with interior pockets, and may be used to stow and transport your laptop too. It has a stitched leather handle and a cotton strap that’s removable. You can get the Senhor Prudencio Bicycle Case in khaki and black leather.
