A spin is certainly not what I am trying to do with my calculations. I have seen first hand what petal bikes can do around pedestrians. Your attempt to play the safety card is based on speculation not fact. It is actually much safer to share the path with speed limited scooters then a bunch of riders flying down the path on their petal powered open frame bikes, they will not slow down when they pass because it takes to much energy to get back up to speed. The full lighting and signal system's on the closed frame scooters make for a very visible rider. It really comes down to the individual rider, scooter style or open frame, if you ride like an idiot, someone will get hurt. I have rode both styles. I enjoy my open frame ebikes but when I need some extra storage and comfort for my ride I hop on my Scooter style E-bike.
