i am going to use a bike to get to + from work when the weather does not force me onto a bus. all i want is something for pavement, no off road, no racing, just commuting. i will be biking in a hilly area so something that will get me up the hills would be preferable (i suppose that means more than just 3 gears). i am also a pretty big guy (6' and 280lbs) so something fairly safe, comfortable + upright as opposed to a drop handle 10-speed racing bike is preferable. lastly, while i do not want to buy crap, i would like to keep it reasonable (tho i do not really know what "reasonable" is for bikes these days.) i used to bike a lot as a kid but i have not done so in a while, so i do not know a heck of a lot. thanks!
