Robert Penn's It's All About the Bike: The Pursuit of Happiness on Two Wheels is a paean to the humble bike; it's the story of why we ride, and why this simple machine holds the power to transport us all. Robert Penn has ridden a bike most days of his life. He rides to get to work, to bathe in air and sunshine, to stay sane and to feel free. This is the story of his love affair with cycling and the journey to build his dream bike; a freewheeling pilgrimage taking him from Californian mountain bike inventors to British artisan frame builders, and from perfect components to the path of true happiness.
