David Rosenberg comes from London. He has completed two degrees in architect and a Masters in space syntax. In the late 1990s and early 2000s he was the Project Architect for the pedestrianisation of the North side of Trafalgar Square working for Norman Forster. He is passionate about cycling and started his own design studio two years ago named after his pink bicycle "Velour rose". He will be wearing a modified cycling suit designed by a friend to match his bicycle. Another friend has made a bowler helmet. He will be using a bike trainer - lent by Brompton who made his bike and will be playing so they can see everything in a happier light. He has brought his folding pink bike, a bike trainer that he sits on and can peddle and generate power via a turbo, a power pack and two soap bubble producing machines, light mirror reflectors, iPod and amplifier.
