Locks are heavy, bulky, and a pain to carry around. That’s why I always carry my bikes inside. For those who aren’t as paranoid, InterLock has a kickstart campaign currently running for an integrated seat post bicycle lock which should keep most crummy commuter bikes relatively safe.

Even if you have a quick release seatpost bolt, or something that only uses an allen, as long as you run the lock through the frame and around a secure object – the bike will be secure. The two 20′” cables are made of 8mm aircraft aluminum cable and the set comes with two keys.

Only $39 for a complete setup and you can choose between black or silver. Campaign ends February 5th, 2013.

Pop past the break to watch a short demo…

  1. Well… might be good for super-low theft areas… but any bike locked with that in the bay area would have a pretty high chance of getting ganked.

  2. 3-2-1. Thats about how long it would take for some thief to snip that relatively thin cable lock and steal your ride. The convenience isn’t worth the substandard protection. Forget this and invest in a decent U lock.

  3. @Sprockets:
    The example shows enough slack, you could send the strand between the rails before locking. But that won’t necessarily work for everyone.

    Yes, but someone has to have the tools onhand. If someone wants it bad enough, they will get it. The trade-off is how difficult for them (and you) that needs to be.

  4. Credit for the design execution. Looks very neat. Already said above, not really the top specification in security. It seems nice enough for quick stops, and as a supplementary lock.

  5. Everything depends on what you actually expect. As long as you need a lock to secure your bike in a safe area for a few minutes, then why not?

    Personally, however, in that was the case I would use a simple lock integrated with the frame, like those mounted in old Dutch bikes – there are models which don’t require any special fittings on the frame which are perfect for such applications.

  6. I would modify the lock and use it as a seat/seatpost/rear wheel lock together with a high end U-lock. that would shoo some peeps away. even in our neighbourhood.

  7. Not everyone lives in a crime-ridden crap-hole where you need two Rottweilers and an atomic bomb to protect your gear. I lived in a place like that for 7 years, but where I live now, this lock would be plenty, no matter how nice the bike.
