In the returned error message you showed the backslash between E: and mydir disappeared, which lets me assume bash uses such as escape characters.

Windows Command Prompt (cmd) however uses backslashes as path separators, hence %CD% contains such. However, bash expects forward-slashes as path separators.

Therefore, to replace all backslashes by forward-slashes, use sub-string substitution, like this:

c:\cygwin64\bin\bash -l -c '%CD:\=/%/my_script.sh'

In case the single-quotes cause troubles as well, use double-quotes:

c:\cygwin64\bin\bash -l -c "%CD:\=/%/my_script.sh"

solution in two steps, first convert the %CD% with cygpath then call bash with the converted path in POSIX format 

FOR /F %%I IN ('c:\cygwin64\bin\cygpath -c -u %CD%') DO SET CDU=%%I
c:\cygwin64\bin\bash -l -c %CDU%/my_script.sh
