Same here in Honolulu, Hawaii. I've been interested in motored bikes for 3 years now, and I've never seen another one anywhere. Everyone just stares as I pass them by, or they're shocked as heck. I wonder what the bus riders think when I overtake their bus.
Hawaii is the moped capital of the world. Those guys run past my house at all hours of the day and night. I'd love to have a moped or Vespa scooter. However, mopeds get stolen all the time here, and I wouldn't want to worry about mine.
No one looks to steal my bicycle, as they would a moped. However, I still chain my bike's frame, the friction drive and my seat when I park.
Thieves love to steal seats and wheels here.
