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. ''A gem of a book ...a joy''. (''Economist''). ''Infectious, exhilarating, highly engaging''. (''Independent''). ''Be swept along by Penn's enthusiasm, humour and refreshing candour''. (''Sunday Telegraph''). ''Enriches your enjoyment of a ride''. (''Sunday Times''). ''As a depiction of a world you might vote for, Penn's does not sound bad at all''. (''Observer''). Robert Penn writes for the ''Financial Times'', ''Observer'' and ''Conde Nast Traveller'', as well as a host of cycling publications. He is the author of ''The Wrong Kind of Snow''.Robert lives in the Black Mountains, South Wales with his wife and three children and commutes to work across a heather moor on a mountain bike.
