I would want my bike to be a single speed, old folks cruiser with springs front and rear and heavy balloon tires. Fenders, baskets all around, a generator lignt/battery light and a seat the size of a tractor seat. In hill country there is no downhill, everything is uphill related to the quickness that you can coast to the bottom of a hill. I couldn't ride uphiil far enough to need gears especially with a load on the bike, I would be pushing it most of the time. (The Vietnamese pushed 500# loads on the HCM trail I have read.)
As far as escapeing from pursuit, I would have to go through something they wouldn't want to go through, probably crawling. eddiegjr
