I was doing a little more research on Worksman....slow night!

One statement up there: "I grew up in that part of Queens and never heard of Worksman until a few years ago."

"Barbara Mishkin, his granddaughter, recalled her grandmother's saying that in those early days Mr. Worksman spent all the family's money on patents. ''They moved from place to place because they didn't have enough money for food,'' she said.
"All three of Mr. Worksman's children ended up working with him. It was his youngest son, Irving, then still in his teens, who struck the deal with Good Humor. That enabled the company to move from Manhattan to a bigger space in Brooklyn. In 1979, Worksman moved to its current factory in Queens....
"In 1979, the city helped finance the company's move to Queens by giving it tax breaks for 20 years. That arrangement ended last fall, returning the company to its full tax rate."

The Good Humor deal was in the 1930's, so it looks like they moved from Manhattan to Brooklyn in the 1930's, from there to Queens in 1979.

I find an old ad for ice cream bikes of unknown vintage and an old invoice from 1940. The ad shows the address as 446-456 Adelphi Street, Brooklyn 17, N.Y. The invoice shows addresses as Office- 8 Cortlandt Street, NYC; Factory- 125 Navy Street, Brooklyn, NY.

From what little I can find on the history, it sounds like Mr. Worksman's operation was pretty limited up until the 1930's, maybe just custom work or something like that, but not regular manufacturing. Their big hit in the 1930's was the Good Humor ice cream cycles. It sounds like they also started making industrial bicycles in the 1930's.

Currently, Worksman sells direct to the public (via their website), and markets certain bikes for recreational use. But I don't know how long that has been the case. As long as they were selling industrial bikes to Ford Motor Company or similar clients, relatively few of those would have ever made it to the civilian market.
