Maybe once you move to the american West and invent a bicycle utility trailer you can haul your motorcycles with!

Living with a 'Utility bike' ethic, as opposed to just owning a utility bike, would generally preclude a lot of 4WD vehicle use to haul motorcycles, yes.

Hauling motorcycles for recreation is something most 'utility cyclists' don't even have to deal with, I'd imagine.

A certain hypocracy would be exhibited by a self identified 'utility biker' taking lots of trips with his 4WD. If you want to 'self identify' as a person belonging to a group you only aspire to emulate, that's self delusional.

The people in the town you live in might question your ethics if your 4WD is plastered with 'human powered transport ' advertisments. And bike shops might question your message if your travelling salestruck is a Hummer with HPV bumper stickers.

If you just wanted to make a buck without actually using your products regularily, you could capitalize on designs emulating from somewhere other than genuine utility.

does that make sense? No apology needed.
