BUFFALO, N.Y. — If it were possible for anything to be hot in Buffalo this winter, it was the newfangled “ice bikes” that debuted at an outdoor skating rink.

The bicycles on ice skates were an immediate hit when they glided onto the Ice at Canalside the day the mammoth new rink opened on the city’s waterfront.

Since that December day, the bundled riders who have ignored breath-taking cold to rent them have convinced inventor Lisa Florczak that she’s on to something. That, and the inquiries from several other cold-weather cities in Wyoming, Michigan, Minnesota and Canada interested in rolling them out next year.

“I had no idea if this would work or how people would respond,” Florczak said on a recent afternoon as some Parkinson’s patients tested the bikes for their exercise potential. “I thought I might end up being the laughingstock of the city.”

Instead, she is relishing being part of Buffalo’s efforts to revitalize its waterfront and draw people year round, even when the Lake Erie breeze is something more endured than enjoyed. The bikes give even non-skaters a chance to try out the ice, along with the warm nuts, hot cocoa and craft beer sold at nearby kiosks.

Florczak’s family business, Water Bikes of Buffalo, was renting pontoon bikes that let riders pedal the Buffalo River in warmer months when economic development officials put out a call for ideas for the 33,000-square-foot ice rink being built nearby on a historic recreation of the Erie Canal.

“They said the ice is going to be pretty large and they thought they might need something more than just skating,” Florczak said.

Curling, hockey and broomball leagues emerged.

“I thought, what a perfect opportunity to go from water biking to ice biking,” Florczak said.

She bought a bike off the rack at Walmart and worked with General Welding and Fabricating in suburban Elma on a design. The bikes had to be sturdy, not tip and co-exist with ice skaters. Prototype testing showed that sharper blades, like on ice skates, were too fast, as were flat blades that worked like a ski.

The finished product is a 26-inch bike that sits on a rectangular base with a duller blade replacing the front wheel. Stainless steel so they don’t rust in the snow, they ride like a regular bicycle, only without the need to balance. Riders brake by pedaling backward.

“It’s pretty neat,” said Dave Wolf of East Amherst after giving a bike a spin. “They take a little getting used to. No sharp turns. But once you get used to it, it’s a pretty nice ride.”

Wolf, who has Parkinson’s disease, said he rides a three-wheel bike in the nice weather and likes the idea of a winter alternative.

The inaugural year had 15 bikes on the ice on weekends only, with riders paying $10 for a half-hour turn. There are plans to sell kits that will let people convert their own bicycles for about $1,500 and the company is hoping for orders from other cities will make for a busy “offseason.”

Ice Bikes of Buffalo, the name Florczak chose for the venture, is laser-cut into the running board. It was important, she said, that her city get its due if the bikes took off. She also wants to keep production local, after seeing relatives lose jobs during Buffalo’s economic struggles.

“It’s been,” she said, “an incredible ride so far.”
