Its crucial to keep the inside of your frame clean, to avoid electrical issues. The large hole behind your horn that's pointed right at your tire, will allow dirt, water, dust, rocks, and mud, to enter into your frame and electrical system. The purpose of this plate is solely to prevent electrical problems and unnecessary corrosion and debris inside your Sur Rons or Segways frame.

You will literally be putting debris directly into your electrical system.
