The Mayor and TfL are investing £55m in cycling this year
More than 1m Londoners are being urged to 'dust off' their bikes and start cycling more regularly, as part of a new mayoral campaign.
London's Mayor Boris Johnson wants existing cyclists whose bikes are languishing in sheds or garages to make more use of them.
The appeal is part of the Summer of Cycling campaign.
The event ends on 21 September with central roads closed to all cars allowing cyclists to travel freely.
"While there's already been a healthy increase in the number of people on bikes, half of Londoners who own a bike aren't using them regularly, and over a million Londoners are still missing out on the benefits of cycling," said Mr Johnson.
"I'm challenging all Londoners who have bicycles languishing in the shed or garage, to dig them out, dust off the cobwebs, and re-acquaint themselves with one of the most glorious ways of getting about."
