Well you got to start somewhere. In Tampa they started a bike share program. I don't know all the details, but it sounds like a similar type of bike the OP describes. Surprisingly, I see them used quite a bit. However, at least in my observations, they are only around the downtown area on the new Riverwalk or Bayshore. I don't think I've seen any out on the open road. If I took a guess they are used by tourist or locals out for a little cycling adventure, but not for commuting or as a vehicular alternative. I could be wrong though.
