When Tiffany Seder and her four kids went inside their house one recent afternoon for a short break from gardening and outdoor play, they left her son’s new bike in the open garage. It was parked behind two cars in the driveway at their Santa Rosa home near Fulton Road and West College Avenue.
It was about 3:30 p.m. on a Monday. Seder’s son, Will, 9, had saved up his money to help buy the Trek Marlin 5 bike less than two months earlier.
When the family returned outside 15 minutes later, it was gone.
“It’s completely violating,” Seder said. “It was somebody who either knew it was there or somebody watching us.”
They searched their neighborhood, filed a police report and checked pawn shops. And they turned to online resources such as Bike Index — an online bike registration nonprofit — and the Sonoma County Bike Watch Facebook group, where residents can post photos of stolen bikes.
In the bicycling destination of Sonoma County, authorities say bike thefts have become bolder, with bikes snatched in the middle of the day, much like the Seder family. But social media has paved a new path to recovering stolen bikes, touted by authorities and local cyclists as more effective than working solely with police.
The Sonoma County Bike Watch Facebook group was started by arts advocate Spring Maxfield in late 2012 after a sudden rash of bike thefts in the Roseland neighborhood.
“I really think that social media in this respect is really effective,” Maxfield said. “It’s known now as a great resource for bike recovery.”
Instead of tacking up flyers around town, bike theft victims can get immediate updates from 1,500 Facebook group members who serve as their eyes and ears in Sonoma County — a place that attracts cyclists with its good climate and array of biking paths.
“Going on the Sonoma County Bike Watch page, it’s crazy. Bike after bike after bike,” Seder said. “It’s pretty remarkable.”
Drew Merritt, Birdhouse Cycles owner and Sebastopol Bike Center mechanic, has recovered two stolen bikes with help from the Bike Watch page.
“I think it’s really the only way to get a bike back,” Merritt said.
Santa Rosa Police Sgt. Marcus Sprague said the city doesn’t have enough personnel to register bikes, and while he is familiar with Bike Index, it’s not used by police.
“We find bikes weekly that we can’t identify,” he said.
An annual average of 166 bikes were reported stolen to Santa Rosa police from 2011 to 2017, but Sprague said the number is “as good as the people who tell us.” From January to April of this year, 43 bikes were reported stolen in Santa Rosa.
“That number is super low,” Bike Peddler store manager Chris Wells said. “I think it could be double that.”
Sonoma County Bicycle Coalition board member Christine Culver said people don’t always report stolen bikes. “And there’s a lot of people who are occasional bikers who don’t miss it right away,” she said.
Police have used GPS-enabled bait bikes to catch thieves for at least five years now, particularly in “trending locations,” Sprague said. There are no city signs that warn of bait bikes, which some towns put up to ward off potential theft.
