I am glad you mentioned about the maintenance... I am concerned because in trying to research a bit I've been reading about derailleur vs internal hub and all the bikes I picked are the former, though the latter seems better in terms of shifting and maintenance. I am wondering if I need to search out the latter or if it really matters that much.

Edited to add: I am able to get 25% off of the powder blue bike (they were running a special which ended yesterday, but I messaged them on Facebook and they will honor the 25% off), but again, not knowing specifically what to look for, I'd like to verify if this is another bike I should look into. Thanks so much for all of your help.
