Cycling was given an enormous fillip by the Olympics and the Bradley Wiggins factor. Now is the time to build on it genuinely and vigorously. So I welcome the publicity you have given the issue and the parliamentary inquiry now in process (Report, 21 January). If, as you point out, cycling is to become mainstream, as it surely ought to be and is in other European countries, piecemeal cycle lanes must be dispensed with in favour of high-quality, dedicated and entirely segregated cycling routes, and the cost involved, a fraction of that devoted to rail and motoring schemes, treated as an indispensable ingredient in our transport budget.
