      Huge help

      Customer service was awesome!!!
      Hey Ike web site indicated the battery top was only available for cityscape. I needed the Ranger top cover. Customer service said he shows the Ranger top cover was in stock. Per his suggestion I ordered the cityscape and he changed it on his end and it worked perfectly 👏

      Battery top cover

      Very happy with the battery top cover. It even arrived early! All the wires hooked up fine. My cityscape is back on the road!

      It fit so that was all I needed it to do. However would love it if it came with install directions even though it was pretty self explanatory I like knowing that if I had a problem I could refer to something
