Cable through the wheel and around a tree or through the frame.And maybe a camo net or build a blind to hide it in.

I have a Yamaha XT225 that I use for hunting on logging roads. I carry my bow in some forks that I attached to the handle bars, or break it down into a case and attach it to the rack I put on it. A hard case would be nice in a spill but this is what I have now. I have not yet come up with something better for my bow; it is a recurve so PVC pipe won't work for me.

I did want to post another idea for you.
Something I have found real handy is a hauling rack over the rear wheel that is attached to the frame.
The rack I have is made by ProMotoBillet, they make them for a lot of bikes. You can google them if interested. I sometimes attach a plastic milk crate to the rack (with cable ties), which is handy for hauling things without having to tie everything down, like a day pack. I sometimes hook a bungie across the top of the crate but for short trips on better roads I don't bother. The crate keeps straps on the pack from dropping down into the wheel or spokes.
You can also put a lot of boned meat in game bags a milk crate and it is pretty secure, and then wear your pack on the way out.

I have a trail bike that I putter around the logging roads. The bow is strung and the string goes over the two mirrors on each side of handle bars. The bow rests on plastic cowling over head light. works as long as Im going slow. arrows are in my side quiver strapped to  rack on rear

If you really wanted to tote your bow in style you could go all out with buckskins on a Harley and a Bear head helmet...    

 

Great looking bike & leathers Ron!

Sorry, I can't help on that. I found that picture somewhere on the Internet and copied it. It is my favorite old time picture, as I like both bowhunting and motorcycles.
