Cyclists are planning a huge demonstration in a bid to force all mayoral candidates to improve road safety.
They will ride from Blackfriars Bridge to Hyde Park on April 28, putting safety at the top of the agenda before the May 3 poll.
Labour candidate Ken Livingstone today vowed to change traffic lights at all junctions to give cyclists a five-second head-start over other traffic. And green lights for cyclists are being considered by Boris Johnson at Bow, where two cyclists were killed last year.
Between 2001 and 2011, 156 cyclists were killed and 4,000 badly injured in London.
The protest ride is organised by the London Cycling Campaign which is calling for safer Dutch-style cycle lanes. At last night's launch transport expert Christian Wolmar also called for the Olympic VIP "Zil lanes" to be given to cyclists after the Games.
