I've been riding a single-speed Strida for about a year. It took me a while to get used to the handling. When I bought it, I had to walk over to a park and practice starting and stopping for an hour before I could ride home without wobbling like a drunkard. I have 2 other bikes, but I use the Strida for commuting because it's much easier to carry up and down stairs and fit onto the train. A typical round-trip commute is 13 miles of riding broken up into segments with a train ride in the middle.

The longer I've had this bike, the more I've grown to like it. I no longer find the handling weird, and I can do things that I could never do on a normal bicycle, such as back up while sitting on the bike. That's surprisingly useful in an urban environment. It's a belt drive, so there's almost no maintenance and you never have to be careful about leaving black chain marks on things.

I never found the bike uncomfortable in any way. I don't feel bumps much more strongly than I do on either of my other bikes, and they both have full suspension. (I am short and lightweight, though.)

One of the best features is the instant fold/unfold that can be done in a single motion. By the time other people on the train have unfolded their bikes, I'm halfway down the platform with mine.
