Sounds like the OP probably knows they don't have the will power to do it. So really, spending anything is likely a waste of money. That being said and OP is willing to give it the old college try, maybe that $110 WalMart Mongoose that keeps popping up is a good option. Before you know it, those two really hard hills will look like ant hills.
Just so you know jjboods, if you should choose to start commuting by bike for 35 RTfor real, that this bike will have to be retired for a better steed.
