what about all the people you passed up when you was on the airplane? how can i wave you down if youre 30,000 feet above? A bike or scooter simply takes you from one place to another where people are at faster than you can walk there. Even if you own it for a few months then it gets stolen it paid for itself. A 50cc scooter is more efficient than a human on a bicycle or walking because a human has to speed alot of time&money eatting and drinking. Have you ever drove a something with a 50cc engine or under? Iif not I suggest you rent one and try it out. If you know how to protect your bike, there is little worry about it getting stolen.
