After the Ghostbusters and Slimer learned the Ghostmaster placed a force field around each of them, rendering their equipment useless, they fled the Firehouse and ran to Mr. J's Bicycle Shop. Mr. J helped them out and gave them two sets of skates and two bicycles since Ecto-1 couldn't be driven around.
