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).
