i dont think adding the word scooters has anything to do with how mature the sport looks.
If you cant live with the fact that you ride a scooter, just like little kids, then quit. This sport is not for you.
If you are afraid to have the word scooters in your brand name, and your brand is designated towards scooter riders, that means your imbarrased about the sport you "support".
emeica isnt called emerica skateboards because they make shoes not skateboard, they are called emerica footwear. however, a company like element makes boards so they're called element skateboards or element skateboarding.
have u people forgotten back in the day skaters used to think bikes were gay ass hell but now the two sports are like cool with each other.... just give scootering time too mature then well be a normal thing,and there will probably be a new sport called XTREME WATER DRINKING
