Prevent the Ride-Away

The folks behind LINKA, the "world's first auto-unlocking smart bike lock," think a would-be thief is much less likely to make off with your bike if it's (1) unrideable because of an immobilized front wheel and (2) screeching as loudly as a jackhammer or power lawnmower. Seems like a reasonably safe bet.

If you've got a bike and a smart phone and are inclined to use the latter to help safeguard the former, check out LINKA's Kickstarter campaign. It runs through June 13 (but has already far surpassed its fundraising goal).
 

   

(Hooray for LINKA's use of Bike Index's database! Theft prevention efforts are better operating in concert.)
