I ride mine 2 miles a day, sometimes 3 based on a variable commute. Mine doesn't have gears or a spedometer so I can only say I am comfortable at the fastest speed I can pedal -- but it would feel unstable to go much faster, say, on a very steep hill.

I'm not trying to imply it feels like a weirdly shaped mountain bike. I'm saying it does its particular job very well. The seating position and narrow handlebars definitely preclude it doing anything other than getting you from the train station to work on urban streets.

I have a real bicycle, too for, well, actually riding a bicycle.
