nope, and the reason is this. I hunt in rough terrain, I don't hunt from stands normally, and even though they might be easier from a cardio perspective, they are harder on leg muscles so the odds of cramps and lactic acidosis are higher than if I'm just walking. in addition when I do see an animal I don't have to slam on breaks and come to a complete stop before unshouldering my weapon(which probably isn't cross slung but would probably have to be on a bike) and bringing it to bear. lastly, if I do stop to follow tracks, or shoot and then have to follow it through brush the bike is staying on the trail and odds of it getting stolen are pretty high. so no it's a stupid idea for me, in my region, for my style of hunting, and probably a lot of other people too.
now if I hunted from a stand on a nice level privately owned ranch in texas somewhere, the bike to and from hunting might make a bit more sense.
