My husband and I are looking to start cycling together. We're just starting out and are looking for something we can do together just to get in shape. He's 6'4" 330+ lbs. and athletic (he played college football, basketball, still works out 6 times a week, eats exceptionally well). So, there's no breathing problems etc. He is looking to take off some of the weight so he won't be so bulky. Neither one of us is experienced, and I found a Kona Hoss Menís Downhill Mountain Bike used. Ideally, we wanted to get a steel framed bike, but is this one ok for him with his weight? Also, we don't have a whole lot of money to drop right now, so the price is pretty ideal, but I want to make sure I'm getting him something that will be worth starting with - sturdy & reliable.
