The other is a bug out bicycle with air free tires, racks and packs all over, maybe even a pull trailer for additional supplies. It is more stealthy, and can go off road on trails. The North Vietnamese moved tons of supplies with bicycles on the Ho Chi Min trail. Each with about 200 lbs of ammo and supplies. They pushed them south when it was too hard to ride, rode them back north to get more. If you don't use a trailer with one, you can move faster than walking.
Another option is use a modified pull deer cart. Attach a 30 gallon plastic barrel, and put whatever in it. It can be placed to balance where the handles are waist high to attach to your belt or backpack, pull it along. Large wheels to get over logs and such.
