Kickstarter products are getting more and more creative, with hybrid creations such as the Memobottle gaining momentum, making way for other how-did-I-never-realize-I-needed-this-before products. Among these is Seatylock, an innovative bike seat that transforms into a bike lock. It works via a folded arm that sits under the seat saddle while the bike is being ridden. The seat then comes off, with the arm folding out and allowing the rider to affix their bike to an external object. With a range of pledge options on Kickstarter, you can head here to pick up a Seatylock for yourself.
