I tried to ride one of the bikes from one Google building to another once and a black security SUV pulled up and started yelling at me. They aren't very good bikes anyway- they are fixies which are kind of useless for rides longer than a block.
Google security can't tell if you're an employee or not at first glance. How would they know to yell at you?
I'm guessing you were riding in the middle of the road or doing something else stupid.
Boston's Hubway bikes are 3-speed, but 42 pounds despite (I believe) an aluminum frame. New York's Citi Bikes are also 3-speed, but 45 pounds.
It is much nicer to ride than any cheaper bike I have owned and I was happy with the price.
