Ever since intellectuals like HG Wells and Bernard Shaw, cycling has been associated with the socialist left. George Orwell wrote of the spinster riding to evensong - later referred to by John Major.
Since 1997, Labour has introduced the £43.5m National Cycle Network. John Prescott, often called 'two Jags', oversaw transport reforms that were meant to double cycling journeys by 2010.
