Indonesian Etsy seller Klemens & Co. makes handcrafted leather bike accessories that are as handsome as they are green. And when we say handcrafted, we mean it--no machines are involved in the production process whatsoever. Designed for a standard diamond men's bike frame, this sturdy bike bag is the perfect unit for carrying small valuables while cycling around town. Made of thick, vegetable-tanned leather, the bag mounts to the frame via three straps that keep everything tight and secure. If you're a regular cyclist and you like the naturalistic look for your accessories, this is the bike bag for you.
