I am looking to buy a new bike for commuting into work (about 5 miles of city riding). At first I was thinking a townie or a lighter weight cruiser would be fine, but the more I rode my husband's electra verse, I realized wanted something lightweight as well - the ride home is all uphill.

I have my eye on a specialized vita or ariel, or possibly a trek fx. Am I looking in the right direction?

A specialized vita in fabulous condition just came up on our local CL. It's a size 55, or large, and I'm 5'6"-5'7". I'm wondering if this will be too big for me? (I realize it's best to test ride, but it's kind of a haul to get out there, so I was hoping to get some feedback here first!)
