Walking around paris

We went to paris to my bank then we walked around and we saw this guy pass infront of us with his i don't know if it is a bike or a motorcyle.Everyone looking at him and thinking if it is bicycle or a motor.I was just too late when i took this photo because the guy already park and left this bicycle.But is really intereting because i never see this kind of thing mostly in paris i saw expensive cars but not this one.
