Gonna be hard to deliver a load of firewood on a bicycle.
One stick at a time. Besides, you won't need all that firewood because of all the exercise, and that way you'll save a tree for the earth and climate change.
The chicoms got ya covered. They been there done that. A single person can move over a metric tonne with one of these oldskool commie carts.
