Unfortunately I am one of those fools: I put down $65 at REI for one of these locks, the 30-inch model a month ago. It’s really light, lighter than one of those inexpensive cable locks you see at Ace Hardware (don’t you just love that name?) for about $15 and which I have been using for years. But it turns out it’s no more effective at thwarting bike theft than the $15 type—just a lot more expensive. So much for disruptive technology; about the only things that will be disrupted are your wallet and your ride when you find your bike has vanished from outside Starbucks. It has steel and Kevlar but so what if it doesn’t stop a thief. The Bike Picking Lawyer posted a video showing that you can cut one of these idiotic locks in much less than a New York minute with a pair of $10 tin snips from Home Depot—see the video. Years ago when videos showed up on the Internet showing you could open a Kryptonite U-lock with a Bic pen, Kryptonite revamped their locks and to their credit undertook a massive years-long recall. I’m not sure Ottolock is going to be able to pull off a similar apologia because the raison d’être of their locks is ultra-light weight. Plus, Ottolock is a child of Kickstarter, i.e. it’s young and not well capitalized. However when a complaint was raised to Ottolock about how you could actually palpate the tumbler to detect the numbers used in the combination lock, apparently they did improve them so that you can’t do that anymore. So maybe there’s hope.
That said if you are in the habit of using a cheap cable lock for your coffee stops [for the record I never let my bike out of sight when I’m on a ride] the Ottolock will be lighter. It just won’t be safer. If you do use an Ottolock, like a cable lock it will only delay a thief momentarily. So you should use the usual tricks in combination with the lock (wrap helmet straps around wheel/frame, use more locks, put bike in high gear, pile bikes together, etc.) And by no means think that an Ottolock (or cable lock) allows you to dawdle inside a store for a few minutes. That’s plenty of time for your bike to be whisked away. Just hope the bike thief goes after easier prey, i.e. a nearby unlocked bike.
