Hello folks, I'm relatively new to trail riding on a bicycle. I'm looking for a bike. I don't want to make a bad decision on purchasing my first one and thought I'd get on here and get some help. I'm a big fellow (6'2") tall and 225lbs. I've been to a couple local shops in the area around San Diego and ridden a few Giant brand bikes. That and cheap Wal-mart style bikes are my only experience with them. ( I rode BMX style bikes when I was a kid) The more expensive $2,000+ Giants felt exceedingly better built than the cheaper ($1,000) ones did. What could some experienced riders offer in advice? Brand, Style, Bang for Buck? I plan on seriously doing this with the intent of riding the trails here in San Diego. I appreciate any information that could help.
