and then come back.
In the meanwhile, you will need to answer some questions.
Budget?
Flat or hilly, (prob hilly, eh?)
What do you carry to work with you, and do you think you want racks or messenger/back pack?
does speed matter to you or comfort?
Do you have an interest in working on your bike, how much maintenance do you want to put into it?
I am a cheap, lazy comfortable slow old man with a flat commute who rides in work clothes and doesn't like to sweat. See signature.
