A new wheelchair wheel that folds into almost half its original size for easy transport and storage has been unveiled by US company Maddak. When folded, the patented Morph Wheel takes up a total of 12 litres of space, compared with the 22 litres it would usually fill when fully circular. This enables its size to be reduced from 24in diameter to the more manageable dimensions of 32 x 12.5in. The folding wheel was originally conceptualised as a folding bicycle wheel by Royal college of Art graduate student Duncan Fitzsimmons.
