Not a new invention, but a good idea. You can go to any vinyl sign shop and they'll have it. There are a lot of companies that make it. If you put all that he has on his bike it will add about 1.5 lbs to the bike. Ask them if they have left over stock they aren't using or it will cost you a ton! When I worked at a sign shop in high school we'd have a lot left over from custom jobs. You can get it in about any color you want.
