A recently erected sculpture along the Lake Michigan shoreline in Chicago is attracting a lot of attention for all the wrong reasons.

The “bike sculpture” along Oak Street Beach in the Windy City is comprised of dozens of electric Divvy bikes that have been retrieved from Lake Michigan by the Alternative Anglers Association led by Glenn Rischke, who discovered the discarded rideshare ebikes while swimming in the lake.

The group collected 22 Divvy ebikes from the lake bottom over the weekend, along with plenty of construction materials, and piled it along the boardwalk to raise awareness about a growing problem city officials have largely ignored, Block Club Chicago reports.

“All of those bikes you saw, including the fencing, came from a 40-foot section of the lake,” Richke told the news site. “We had to remove a ton of the fencing before we could even get to the bikes.”

The weekend haul followed other outings in Montrose Harbor, near the Shedd Aquarium, and other locations where users have simply dumped the ebikes in the water, pulling dozens ashore over the summer.

“We’ve pulled out over 60 bikes in maybe 2,000 yards’ worth of lakefront,” Rische said.

“Pretty infuriating, yeah,” he told NBC Chicago. “I think this speaks to corporate accountability. It speaks to the city.”

The city owns about 16,500 Divvy ebikes and scooters docked at more than 800 stations across the city, an operation that’s managed by rideshare company Lyft. Rische told Block Club it’s “maybe not surprising” neither the city nor Lyft have made significant efforts to address the issue, but he felt compelled to take matters into his own hands to “advocate for better waters.”

“It’s been annoying to me and to a lot of people,” he said. “I think the story is more about what the company is doing to get these bikes out of the lake. I feel like if we weren’t doing this, there’d be 60 bikes still in the lake.”

That’s a concern for Dan Pogorzelski, commissioner with the Metropolitan Water Reclamation District, who told NBC Chicago the issue could pose a threat to drinking water.

“I was amazed when I saw what Glenn and the Anglers Association were doing,” Pogorzelski said. “Especially when you’re talking about the e-bikes, my worry is when that battery gets in the water it will leach in, so it’s definitely not healthy.”

The Chicago Department of Transportation and Lyft, meanwhile, seem far less concerned, issuing a joint statement on Sunday that largely ignored the environmental concerns.

“We evaluate each bike that comes out of the water to see if it can return to the fleet or if there are parts that can be re-used on other bikes,” the statement read. “The city is working with Lyft, the divvy operator, to improve rebalancing and increase valet services along the lakefront.”

The CDOT, which ignored a request for comment from Block Club, told CBS News the department is working to help riders find docking stations along the lakeshore.

Durrell Robertson, a field service operator for Divvy who worked to dismantle the bike sculpture on Monday, told Block Club all of the waterlogged ebikes will head directly to the trash.

The problem, which has also been documented in viral TikTok videos, surfaces as Divvy hiked rates 10% this year, with plans to expand its network by adding 250 more stations by 2025, ABC Chicago reports.

“Earlier this year, Divvy expanded its service area to all 50 wards and today’s launch of new stations will continue to increase bikeshare access, particularly on the Northwest, Southwest, Far South Side,” according to an October post on the city’s website. “Eivvy is also in the process of adding nearly 3,000 new classic bikes to the fleet to ensure users have a healthy balance of ebikes and classic pedal bikes.”
