Riding your bike can be a lot of fun. But you are going to need a lock to keep your bike from getting stolen. The Seatylock happens to be a saddle that turns into a bike lock, saving you from having to carry a separate bike lock. It has a universal adapter, which lets you attach it to any bicycle. The Seatylock will be available in 2 models: Seatylock Trekking & Seatylock Comfort.
This bicycle saddle transforms into a one meter bicycle lock quickly. Like what you see? You can get it on Kickstarter.
