I ride a step through as a commuter and like it very well. The step through design is quite convenient once you get used to it.
I wondered if it would be flexy at all but so far it is stiff yet responsive, more so than my touring mtb and I'm 210lb's.
This season I am setting it up for light touring/randonee stuff. I already have a frame and handlebar bag so I may just go one step further and get a seat post bag as well.

I just posted this pic yesterday but here it is again.



It started out with flat riser bars with twist shifters which were fine but I decided to put trekking bars on. That was a straight swap over and it worked well.





But then I decided to do a dropbar conversion on it. I didn't want to spend a lot on bar end shifters (can't find any used ones cheap around here) but I discovered new shimano friction/index stem shifters that fit my stem for only $17 so I added them and interuptors.



From here I plan to swap out the crankset for one with lower gearing as I find the current one a little too high for big hills. My knees are hurting this season. It's a biopace triple with 175mm arms and a 28T granny and I am going to try going to 170mm arms with a 42T gear. Total swap out will be approx. $100.
