I have a 07 Ruby Pro and now that early mornings are lighter I also plan to commute to the train station. I will not use my Ruby as I never lock her up. Even in the nicest areas here I am so afraid of some kids that have nothing better to do vandalizing her and the train station seems to be the place to ride and do tricks on skateboards.

I am just about done in making some changes to my mtn bike (smooth tires, rack etc.) to use to commute. I have been running errands on it. I now just need a kick stand as I don't even plan to leave this bike at the station, but down the street in "the town" where there are stores so I can lock it up to a lamp post since my town of Bellmore doesn't even have bike racks. I feel parked in front of little quaint shops there is less of a chance of someone doing something to it.

To answer your question, I would get a 2nd bike. If I find commuting/errands by bike is working for me, I will eventually invest in a lighter bike.
