If you have a bike, keeping it locked up tight while you’re at work or in class is of high importance. No one wants to come outside to find that their mode of transportation has been jacked. While there are a ton of different bike locks out there, they only do you good if you remember to bring them with you. If you’re worried you might forget to bring your lock along, then why not just make it part of the bike frame?
The Interlock is a seat post with a built in lock. It has two 20 inch cables that have a weather resistant cover, and two keys. One bolt will make sure that your seat stays where you want it. You’re supposed to wind the lock through the frame, so that the bike can’t be stolen even if the seat post is taken off. Currently it’s a $39 pre-order, and from the looks of things, it only comes in black.
