Lots of cool bikes built for hunters, hunters here still use Tote Gotes, heck, they were designed for hunters trying to access game in Utah's rugged back country. I am working on a Brooks bike now that I think could easily be modified for hunting.
You will notice a lot of the Gotes and Gote knock-offs will have a flat area behind the seat, some people have added a second seat there, but a lot of Gotes still have this open space behind the seat, that open space was for hauling game. Never seen a Gote hauling an elk, and I think you would have to quarter it to do it, but I have seen some monster bucks strapped to the back of a Gote.
