Hello all,
I am new to biking and would like to ask for your opinion. I have been looking in the bike shops and the cost is a bit daunting. However I found this one on craigslist and I was wondering if a mountain bike would be ok for commuting to work (3miles) and just riding around town. If i go to a shop ill be looking a bottom of the line hybrid, the cheapest of which seems to be $350-450 before tax.
