"Walking by foot is a rather slow way too evacuate during an emergency. Bikes are one of the most energy efficient ways to travel by muscle power. An individual can normally travel many times the distance one could by foot per day using a bike. Another major advantage is that equipment can be loaded either directly to the bike using special bags or be drawn behind the bike on a trailer, this mean that much more equipment can be brought than would be possible if an individual would have to carry the same amount of equipment. There are many different models of bikes specialized for different tasks like being used in the city or off-road, find a bike that suits your specific needs. There are also bikes thats especially designed to carry heavy loads like the Transport from Trek. If you are on a budget it can be worth checking out the second hand market. "
