What is "curricles"

Usage examples of "curricles".

Those were the days when the Prince of Wales had just built his singular palace by the sea, and so from May to September, which was the Brighton season, there was never a day that from one to two hundred curricles, chaises, and phaetons did not rattle past our doors.

I fancy myself a little in that line, so my proposal is that we race our curricles and four from London to Brighton, tigers up, on a day to be named.
