These are great bikes, of course, but I'd opine that you almost have to live in a heavy traffic, urban setting these days to appreciate one.
I cannot picture trying to ride one of these on a modern - "get outta my way or die!" - freeway or major busy street, or near any shopping malls, major thoroughfares, etc. You would get run over almost immediately.
On the other hand, to maneuvor this down a endlessly traffic clogged urban street might be an advantage. One up on a push-bike?
If I had a 'downtown' job, and lived in the inner city, I might consider one... but thank goodness I don't!!!!
This could also be a good pit bike, or a farm bike as well.
