I ride all types of bikes. My Bianchi is SS/FG with a flip flop hub. While I have ridden it on long rides out in the country; the geared road bike is better suited for that.

Around town, it's the FG. My wife tends to vary her speed so it's far easier to match her on the FG.

I "need" a bike I can just hop on and go riding with the granddaughters. A SS with platform pedals would do well for that and provides the perfect reason to build one up from my stash of frames. ;-)
