C:\cygwin\bin\bash.exe -c "command"

You will find that successfully navigating the Command Prompt, Cygwin's and "bash -c"'s escaping rules to be entertaining for advanced commands.

You can also achieve similar with mintty.exe -e (which will launch the terminal emulator, instead of using an existing console window, or opening a new one). Similar fun with escaping unusual commands.

See, for example, https://github.com/ocaml/opam/blob/43e4c778/appveyor_build.cmd#L93
