Hey guys I need a little advice. I built a custom quad recumbent (quadrecumbent.blogspot.com) but I haven't been real happy with it for various mechanical reasons. I can get it to work but it's going to need some work. Besides that it's heavy. I'm looking for an inexpensive ride, preferably a mountain bike. I'm on a tight budget due to buying a new house. My main concern is the wheels. I'm around 450Lbs. I need to get back going again and my quad isn't working for the area we live in. My dad bought a bike at "Wally World" the same time I bought my donor bikes. It's a 26" with suspension. He added a wider seat but hasn't rode since he bought it. I'm thinking of trying to use that. Any suggestions?
