Yahoo! Purple Pedals — "Purple Reigns"
The problem
Yahoo! wanted a physical, roaming experiment in location-aware, always-on photography — years before that was an ordinary consumer idea.
The approach
Build the capture device into something nobody would look at twice: a bicycle.
What was built
A solar-powered bike, 'Purple Reigns,' with a swiveling onboard camera and satellite positioning, auto-uploading a photo every 60 seconds to its own Flickr page as it moved between caretakers.
The outcome
Gavin was the bike's Southern California caretaker for several weeks, riding and documenting the leg for a planned 'Purple Reigns in Venice' recap on purplepedals.com.
In 2009, Gavin became the temporary caretaker of “Purple Reigns” — one bike in Yahoo!’s “Purple Pedals” family — for a multi-week leg through Southern California.
In his own words, from the Flickr post announcing it:
“Purple Reigns is no ordinary bike. Purple Reigns sort of has super powers and employs green-consciousness. Purple Reigns is solar powered and communicates with satellites. Purple Reigns uses that natural power to take photos with its onboard camera, which swivels and uploads images every 60 seconds to the bike’s personal Flickr page.”
The bike passed between caretakers city to city, each rider adding to its public, live-updating photo feed before handing it on. Gavin’s leg was meant to become a “Purple Reigns in Venice” recap on the project’s own site, purplepedals.com.
Verified independently, 2026-08-11. The bike itself checks out against Flickr’s own developer blog, still live: “we have 20 purple bikes tricked out with Nokia N95s geotagging photos and uploading them to Flickr as people cycle round” — matching Gavin’s account almost word for word, down to the 60-second capture interval and the swiveling handlebar-mounted camera. (Flickr was a Yahoo property at the time.) The bikes were Electra bikes painted Pantone 2602 C. CNET and Lifehacker both covered it contemporaneously.
⚠️ What’s independently confirmed vs. what rests on Gavin’s word: the Flickr Bike program
itself, its technology, and its Yahoo ownership are third-party verified. That Gavin personally
was a caretaker for the Southern California leg is source: gavin — his own dated Flickr post and
photos, not independently attested elsewhere. verification: defensible reflects that split: the
program is real and documented, his specific participation rests on his own contemporaneous record.
