Steep inclines, like the Statue of David hill by Delaware Park in Buffalo, are avoided. Conversely, Linwood Avenue's downhill is divine. With speeds averaging 8 to 12 mph, Karagiannis and his colleagues bike from 15 to 18 miles each day. Recently, Karagiannis logged a 26-mile day.

"We're really limited where we can go," Karagiannis said. "I saw an ice cream scooter in Hong Kong a few years ago, but I saw them over and over in India. I get home and called like 50 places looking for one. No one I called will add the freezer sidecar, and no one will insure motorcycles for business use."

For now, Karagiannis will stick with his cargo bike – and his altruistic commitment to both ends of the ice cream chain.

Recently, 100 thank you postcards that Karagiannis collected from a school assembly were packaged and mailed to one donor.

Ron Caudle lived in Puget Sound, Wash., when he made the $100 donation after watching a story featuring the Ice Creamcycle Dude on television news.

"I like the idea because you're giving kids something and you're teaching them to say thank you," Caudle said. "I wrote the check out almost a year ago. It's nice to know you donated to kids, and that's cool. More people should do it."
