I am hoping to find a mountain/hybrid bike for a decent price (under 400).. I am 6 ft tall and 230 lbs.. and am just looking for a bike to get started on that i can ride to and from work (about 7 km). I am not looking to go on trails or anything, just mostly want it for a healthier commute. Eventually, maybe in a year or 2 i will upgrade as i get more into it, but for now i just want something to get my foot in the door. Can anyone recommend a model that might fit that criteria?
