Twins Paradox Theory
Step by step diagrams for a battery powered
cargo trailer which pushes a bicycle (or
more likely, a three wheeler unit, rather
than trailer-bicycle).
The links to the parts suppliers are
outdated, but this document can still
serve as a guide to the issues involved
in designing a battery powered vehicle.
