Cycling is not being promoted or funded well enough by the government, a sustainable transport watchdog says.
The watchdog wants an extra £70m of investment
The National Cycling Strategy Board said the level of cycling in Britain is among the lowest in Europe with only 2% of journeys being made on two wheels.
Philip Darnton, the board's chairman, says an extra £70m is needed to meet government targets on reducing congestion and enhancing air quality.
Ministers say spending on cycling has risen from £29m to £39m since 2002.
But Mr Darnton says he can see "no overall strategic commitment" to cycling at ministerial level.
Only one in every 50 journeys made in the UK is currently made by bicycle, he told BBC Radio Five Live.
Last June ministers abandoned the target of raising this figure to 6% by 2010.
But the government has pledged to spend an extra £10m to link the UK's existing cycle lanes to schools around the country.
