The Guide Dogs charity has warned cyclists to take extra care near guide dogs.
Boris Johnson pledged to increase the number of people getting around London by bike with the Cycle Hire Scheme and Cycle Superhighways.
More than 1, 000 cyclists and drivers staged what they've called a 'die-in' tonight.
The charity Guide Dogs has released a video showing the risk to guide dogs from cyclists who take shortcuts on the road. The video shows cyclists going through red lights at pedestrian crossings and cycling on pavements.
The charity Guide Dogs has warned that cyclists need to take extra care when they are riding near visually impaired people who are using guide dogs. In a survey, it found that a quarter of guide dog oweners in London had been hit by a bike. And 70% of the dog owners had experienced a near miss with a cyclist riding on the pavement or through a red light.
The charity is asking cyclists to ring their bell or call out if they see a person with a guide dog waiting to cross a road. It also warns against riding up behind a guide dog in case the animal is startled.

A coroner has warned cyclists of the dangers of ignoring red lights after the death of a young woman at Bow Roundabout.
Venera Minakhmetova became the third cyclist to die at the roundabout in two years when she was killed in a collision with a lorry at Bow Roundabout on November 13 last year.
Mary Hassell concluded that the 24-year-old "most likely" cycled through a red light prior to her death.
She said many cyclists went through red lights but did not suffer the same "devastating consequences" by "virtue of luck".
"It's important that I'm open and honest about the cause of this collision, for no other reason that other cyclists need to understand what dangerous behaviour contravening a red light is, and that there are potentially devastating consequences," Ms Hassell added.
Using the latest online mapping and lobbying technology, Londoners can quickly and easily enter their postcode to locate their ward and then email their council election candidates calling for their support for the specific Space for Cycling measure identified for their area.
They can also use the new tool to see what is being called for in all wards in London and, as the campaign progresses, track responses from candidates.
