#2380: Biquad

Today’s invention allows cycling to continue even on frosty roads.

Two cycles have their seats removed and are then joined by a single brace which slots into the seat post location on each and keeps the frames parallel.

This component has a single seat attached, as shown.

A rider can sit and propel this stable, four-wheeled vehicle using the two inner pedals, whilst steering via the inner ends of the handlebars (which could be linked together to coordinate the angle of turn).
