I've been using one for 7 years and can't really hunt without one now. They are more reliable than a 4 wheeler but do require maintenance. If you're not handy, it could be costly running to a bike shop to change a tire tube or chain. They aren't terribly complicated if you know the basics. In six years I've changed or replaced almost everything including the motor. Keep them dry and clean and on the logging roads and they last a lot longer. Trust me.
