A bicycle lock is the first (and sometimes best) line of defense against having a bike stolen. No lock will deter every would-be bicycle thief, but a good lock and chain is necessary or those times when you need to leave a bike for “just a second.” The problem is that it often takes longer to lock up the bike than it might to say, drop a letter in the mail at the post office or pick up that takeout order. In those cases locking a bike can be annoying, but still so necessary.
The InterLock, which is now raising funds via a Kickstarter project, could simplify the procedure to lock up one’s bike by including a cable system within the seatpost. This means the lock and cable are with you wherever you go and this system makes looking up the bike a snap.
