I thought that's what this was at first, then I realized the video is just sped up.

I'm from Arvada CO and I'm allowed to drive my Honda ruckus in bike lanes on the road since I'm 50ccs or less, I never see actually bikes though, feels as if all ebikes just use the sidewalk lol

Well there's not a motorbike lane, and it's a bit safer than lane-splitting, so we can share. It's not like OP is blasting past bicycles doing faster than a fast bicycle can.

But also I'm 99% sure that's a bicycle.
