Hi,

I am thinking about a second bike and would like to keep it in the office , for random /lunch/after work rides. I have my main bike that I use on weekends etc, and started thinking about getting something like this - Vice 2.0 Bicycle : Fixie & Fixed Gear Bikes | State Bicycle Co.

Or maybe this - http://www.wiggle.com/quella-varsity...-cambridge-20/ ?

Would this be a good singlespeed bike? I can't tell what size the chainring and rear sprocket is, are there options?

Any recommendations for ready to go/off the shelf cheap singlespeed bikes under $400 if at all possible ? Doesn't have to come with saddle/tires/handlebars to keep the cost down as I'll supply my own.

Thanks much!
