The Seatylock is your garden variety bike seat with a twist. It actually attaches with a quick release on the post. Pop it off and it unfolds into a meter-long solid bike lock, which solves 2 problems: theft and where to keep your lock.
Design-wise, the creators put a lot of thought into it. First of all, it’s designed to be compatible with pretty much any bike on the market. Simply slip it in and adjust it to your preferred position. There are two types of saddles available, one for trekking and one for comfort, and they come in 15 colors and styles.
The Seatylock is definitely a smart way to make sure you’ve always got a lock on you. Kickstarter has this product starting at $85. Check it out here, and stay tuned for a full review.
