Quirky invention: a bicycle that can be ridden on water.
Various shots of inventor William Ratcliffe riding his pedal boat down river. Boat looks like conventional bicycle except it has floats instead of wheels. He passes some girls rowing on the river, they wave at him. He goes under a bridge. M/S of Ratcliffe hauling contraption onto bank with help of co-designer Peter Robinson. They set about making some adjustments to the cycle. Cycle may sound quirky but appears to work really well!
Note: alternative spelling of inventor's surname in paperwork: Rackliffe.
