So how did our heroes transform themselves into wired wonders taking inspiration from just an electric motor from a small fan and a toy bicycle?

The Green Team's Challenge

Using an electric motor taken from a truck’s hydraulic pump, the Green Team constructed an elaborate set-up involving our hero being strapped into a climbing harness suspended from a wooden frame. Grooves cut into the centre of castor wheels, taken off a trolley, ensured they coupled onto the wire above this frame. Flanges were attached to either side of the castors as a precaution to make sure the wheels didn’t slip off the wire. Meanwhile, a battery attached to the electric motor was used to power the back wheel to enable the entire structure, including The Mighty Jupiter, to move along the wire. When it came to stopping, our hero simply pulled on a wooden lever that was hinged in such a way as to force a rubber block against the wire, thus jamming it.

The Red Team's Challenge

Taking a couple of old bicycles welded together, the Red Team created the superhuman cable car that is Sgt Cosmos. With the bikes flipped over, their two wheels were replaced with smaller wheels that were hung onto the wire, with our hero suspended beneath as if on a hang glider. Having two wheels produce stability. Meanwhile, a motorbike battery provided power to a car starter motor for propulsion. But because this motor moved too fast, a couple of belts, taken from a video recorder, were used to gear it down to create a more manageable speed – from small fast wheels to larger slow wheels. These belts ultimately turned a drive wheel attached to the wire to provide movement. For brakes, our hero pulled on traditional bike brakes attached to brake blocks that gripped this drive wheel.
