This is the story of Peter Cheung (C.Y), and his father, who became a wheelchair user after suffering several strokes. Ever since his father's 3rd stroke, back in 2011, Peter Cheung realized that at that time the wheelchairs available in the market were either too heavy, too expensive or bulky. On top of that, Cheung has back problems due to genetic issues, so he couldn't really continue using the the manual wheelchair they used at first. He then noticed he needed to create a new kind of power chair, one that wasn't heavy and that could allow his father to move around easily.
