I am an avid mountain biker, and I hunt by bike all the time. Usually I will holster my revolver towards the back of my left side, grips facing outward, so I just turn my hand back and grab it. This way, it doesnt get in the way of my pedaling, its quick, and its out of the way enough to wear a day pack. We do a lot of long day trail rides, 20-30 miles, and this is how I carry my big boys for bear protection, works great. When we do those rides, every 1/2 mile of so we just start yelling very loudly for a little bit, keeps the big critters out of the way. I do leather working and am starting to draw out a back holster for a rifle for bike riding. Usually I strap it to my pack, but you can't get to it quick.... We will also take out bikes until we can no longer ride out into the woods, and then start hiking. Biking in gives you a huge speed advantage and you can cover much more area in one day, even if you and up hiking for a while.
