i think i need a spring energy-storage mechanism. Maybe a very large
wind-up clock motor?

the scenario is: a slightly-valuable commodity originates at the top
of a mountain. More or less a bushel at a time. there is an existing
paved road. the commodity fetches a price, but not enough to pay for
very much transport.

the concept is to use a cargo bicycle, maybe with trailer, to carry
the items down to the bottom of the mountain, "winding up the clock"
on the spring-storage.

at the bottom, the load is transferred to buyers. the now very-much-
lighter bicycle is to be driven UP the mountain, using the stored
energy.

This is a surprisingly tough wish. It would have a huge world-wide
market with any cyclist who would like to get back a little sweat
equity from freewheeling down hill - on the next uphill stretch.
