I'll participate if there is interest. There are more than a few hunters here that have ebikes.
The Rad basket can mount either way up front and on the back. Part of the choice has to do with the size of the racks. The QK rear rack is short and rear edge has an uplift to it.
I mounted it the wide way to have enough width to mount the Koplin grips to carry my xbow. Mounted the other way, it would have put the butt of the bow in close contract to my back. I also felt that if I carry any weight in it, having it centered over the rear axle vs partially overhanging the rear wheel would be more stable.
FWIW, if you use the bike a lot for hunting, having an additional small rack and basket up front for light things would be a good idea.
