Bike Spike

LoJack + OnStar + Fitbit for your Bike

Every biker in San Francisco needs this. So much theft. $129 isn't a bad price.
$130 + $60 for a year of use means you're getting close to $200 for the first year of use, which is roughly half the price of my bike. Even my friends who ride nicer bikes would have 1/7-1/4 the price of their bike tied up in a security system that doesn't replace the traditional ~$100 locking system. If it's pitched as more than a security system (more on that in a bit) the price doesn't seem expensive. By security fasteners it looks like they mean Torx Security screws, which are super common in basically every extended bit set, they are also really easy to loosen with smaller flat screw drivers (depending on the strength of the security pin you can either leverage the driver against the pin or just bend the pin out of the way). Any serious thief will not have trouble removing this device, so the hope seems to be that either the thief doesn't notice the device (I have no idea if this is likely or not, but it's *unlikely* if these get popular) or the device removal is designed in a way to cause damage to the frame (would deter thieves who spotted it, damaged frames sell for less. This would also deter people with nice bikes from installing them) Obviously this is from a quick glance over their site, I could be wrong about it. It looks like a really awesome product, but it seems like a conflicting pitch, both security (which I am dubious of) and personal tracking features (which I identify with more, but could be solved by linking to my phone and thus not requiring a monthly service fee) and crash detection etc.
I saw this a month ago and had similar concerns to Will. I have a reasonably expensive bike and I still wouldn't buy this. These guys being angle-saws and bolt cutters... my instinct is they'll quickly add something to disable this (eg, cut through the body of the device, remove the "security fasteners" from a safe chop shop?). If this could be fitted *inside* the frame, so thieves lead police up the supply chain, that *might* help. But the economics of bike theft are the real problem.
Great perspectives on the security part of this product. Especially like the article @staringispolite posted. :) I view bike theft as an opportunistic crime. Any bike of sufficient value will do. I find it unlikely that thieves go out with intent to steal a specific bike from a specific person. Based on that view, a thief is likely to simply pass up a bike with a device like this in favor of a lower risk target if one of sufficient value is available. On price, completely agree that this is aimed at the upper end of the market and isn't a fit in the lower end.
@heydjeff — You're absolutely correct about bike theft as opportunistic crime, but this device is designed to be hidden—i.e.: thieves would have to know what it is, and that it exists, to be deterred by it. If your aim is to convince thieves the bike next to yours is an easier steal you might have better luck with a blinking LED sticking out of a hole in your frame, or big stickers for an embedded security system.
