I think that the differences are what makes scootering unique. With bikes there's a bit of a difference in bar size, frames are different but all look the same, with skateboards they're all exactly the same save for width and concave, but with scootering there's so many different styles of parts, whether it's 3 piece bars, crow-style bars, T bars, etc, all different heights and widths, I really enjoy seeing a group of people riding completely different setups. I don't want there to be just one standard size that everyone accepts.
