The Christmas window display at Frank’s Bike Shop on Grand Street is a Lower East Side tradition. Greta Cohen sent along a few photos of this year’s version. A few years ago, owner Frank Arroyo told us dressing up the windows create his favorite LES memories. He loves “fixing up the windows for Christmas and watching the kids come by and smile,” he explained. “If you can bring a little joy to those kids at that time of year, it’s really special.” Frank’s Bike Shop has been located at 553 Grand St. since 1976. The store is open 9 a.m.-7 p.m. every day except Wednesday. Anyone wishing for a new bike for Christmas or Hanukkah?
