Get a back pack that you can strap the gun in vertically. I'll post a picture tonight of my setup. That's is the safest way I have found. Most of my guns would never ride with me on a bike; they cost more than the bike.
Like this, but mine is even more basic and can't be drawn without taking the pack off: http://www.eberlestock.com/Tactical%20Master.htm
If you are planning on having something for a quick draw, well I would forget that idea. There is no quick draw with a long gun on a bike, unless its sawed off shotgun like the terminator.
Having the gun mounted to the bike is not an ideal solution in my opinion, there is no good way to do it that I know of.
