The inventor who specialises in making miniature objects has a new big idea. A collapsible bike designed to fit a commuter journey as easily as it folds to squeeze into a bag...It stands out from the competitors as an "ultra-compact" bike for "short hop" journeys - two miles from home to the Tube or from the train to the office.

Truths often come from the mouths of babes and in this case from a Year 7 class of 11 to 13-year-olds on an art trip to draw Tower Bridge.

They tussled to ride the bike. Declared it "lightweight and cool", "better than my BMX."
