In a statement released later Sir Bernard Hogan-Howe added:
I was expressing a personal view as a non-cyclist and I would like to clarify my position.
There is no doubt that despite the growth of cycling in London, it has got safer and its cost effectiveness and health benefits make it an attractive option for many people.
Cycling is an important part of our city's transport system and the work the mayor and TFL have done to get people on their bikes as safely as possible is commendable.
