Now crowdfunding on Kickstarter, Seatylock is a bike saddle that transforms into a lock. The Israeli design comes from the makers of Foldylock, a previous Kickstarter success. The new security accessory is installed just like a normal saddle and fits any bike frame. Made of high quality plastic, aluminum, and carbon steel, the product is rust-proof and scratch-resistant. The durable design withstood 10,000 test cycles and is promised to be comfortable as well. Available in a range of colors and patterns, there is a Seatylock for every cyclist.
