PHILADELPHIA (CBS) – Thursday marks the launch of Philadelphia’s much-anticipated bike share program, Indego, but here’s one thing you may have forgotten: a helmet.

No worries, because Uber is apparently bringing Philadelphia cyclists a Nutcase Metroride helmet on demand in exchange for a $10 donation.

Riders are instructed to open the app and request HELMET. Shortly thereafter, a driver will arrive with said helmet, which will be exchanged for a donation to the city’s Bicycle Coalition.

The helmets are available from 63rd Street to the Delaware River from west to east, and Lehigh Avenue to Pattison Avenue from north to south.

“Uber is committed to connecting Philadelphia with safe, reliable, and affordable transportation options,” the Uber blog says. “And with this week’s launch of Indego, Philly’s new bike share program, we’re extending that commitment to bicycle safety.”
