Bike Reviews

I want a mountain bike that can be used on a daily basis for both road and trail.
height: 6 feet, 0 inches
weight: 190lbs plus backpack
expected price range: $300 to $500
At first, I stupidly bought something for $50 thinking I could use it to ride to my college campus and back. There were many headaches fixing the piece of crap since the parts were so cheap (particularly the wheel bearings). So, I have had enough of that and want something better. What brand or model performs consistently well and why? Also, any USA bike stores you recommend or is it just primarily the local shops that are good?

I’m an athletic and fairly muscled 38-year-old man. I’m 6′6″ tall and I weigh 255 pounds. I live south of Anchorage, Alaska — a great place for mountain biking with an abundance of open terrain and trails.
I’m new to mountain biking. This summer I’d like to switch over from my past routines of prolific hiking and jogging to biking.
I need a recommendation on a mountain bike for an individual my size. My price range is $3000-$5000.
Thanks!
