People really don’t want to carry their bike locks around with them, do they? Over the past few years, we’ve seen locks that fit in a water bottle cage, get strapped to the top tube, or that are even worn as a belt. The InterLock’s approach is particularly interesting, however ... it’s integrated into its own seatpost.

Created by Vancouver cyclist/entrepreneur Adrian Solgaard Janzen, the InterLock consists of a key-opened 8-mm braided steel cable lock, that is stuffed inside a 27.2-mm diameter seatpost when not in use – 27.2 is the standard diameter for road bikes, but not necessarily for mountain bikes.

The two ends of the lock stick out of the post just beneath the saddle, allowing the user to grab them and pull out most of the cable when it’s time to lock up. A bit is retained inside, however, keeping the cable and post attached. The cable can then be run through the frame and around an adjacent immovable object such as a bicycle rack. In that way, even if the seatpost is removed, the bike still can’t be stolen. Solgaard Janzen also suggests that his lock could be used in conjunction with a harder-to-hack U-lock, for added security.

Adrian is currently raising production funds for the InterLock, on Kickstarter. A pledge of US$39 will get you one, when and if they become commercially available – at that point, the retail price is expected to be $50.

A demonstration of the lock can be seen in the pitch video below.
