They may be a bit more $$ than other "City" bikes, but they're robust and very well constructed. I'm not sure how rigorous you will be with your bike, but these type of bikes are made to be flogged on a daily basis and not flinch. If you do make it up to NorCal, another shop with few models available:

Good luck.
