You're still road huntin whether it's off a bike or out of a truck, just more effort. As long as either are used to get to the point to start your hunt it shouldn't be an issue.
Use to hunt the South side of I-90 at exit 38 and it was a 20 mile drive to the clearcut at the top of the ridge to hunt grouse, since the road washed out and the forest service is not going to fix it, nobody will get to hunt up there until they log the area again, if they ever do.
