Considering you're purpose for the bike, I would suggest a better bike. For $50 you can get the giant sedona not top of the line but it is only $219.. or the Boulder SE for $249. Either one will last you ALOT longer and you can have the bike shop swap the tires right there for just the cost difference in the tires. And you will get a properly fitted bike with ALOT better components and wheels. There seems to be a big misconception of lower end bikes at a LBS, that you are going to spend $500 vs the $200 at wallmart. YOu can find a lower end bike at the LBS for around $200-300.
