The explosion in popularity of bike share programs has one negative side effect: tons of people in major cities now ride bikes in lots of traffic without a helmet. The attraction of bike share programs is that you don't have to plan, you can grab a bike whenever you need one. But nobody wants to carry around a traditional bike helment just in case. Quirky could make a stylish, collapsable or foldable bike helmet that would fit discretely into a purse, briefcase, or other moderately-sized bag.

Bike commuters worldwide through two avenues: direct to consumer, and through bike share programs themselves. Imagine if every bike share program offered new users the opportunity to buy one of these helmets at the time they create an account.
