Theft-proof bike lights

I love great design.

One afternoon last year, Menn and his business partner, Tivan Amour, headed out to Kendall Square in Cambridge, Massachusetts, to invite passersby to walk away with their theft-resistant bike light. The team announced in poster board and Sharpie: “Free bike lights… if you can steal them.” Next to the light, Menn offered an array of bicycle light–busting tools: needle-nose pliers, an Allen wrench, lock wrenches and heavy-duty plumbing wrenches. If strangers could pry the light from the bike in two minutes (“No opportunistic thief will spend more than two minutes,” explains Menn), the light was theirs to keep.

Excellent way to beta-test.
