Has anyone ever seen a radar detector mounted on a bike and if so post some pics i heard it looks kinda dumb

Look into the K40 stealth detector, though they are pricier.

I use to have a rader detctor on mybike i drilled holes in the windsheild(i had a spare) to match the ones on the mount and used lp windsheild screws (alum) it worked great. sorry i have pics that winshield is in a better place now .
