Interactive video: Cyclists will outnumber car drivers entering central London in rush hour in the next few years, according to figures from Transport for London (TfL).
The number of car drivers fell from 137,000 in 2000 to 64,000 in 2014, while those of cyclists trebled from 12,000 to 36,000 over the same period.
TfL says the shift away from private cars to public transport and walking and cycling is "a feat unprecedented in any major city".
Big changes are now happening on the streets of London in a bid to make cycling safer.
The capital's longest and newest segregated bike lane has just opened across Vauxhall Bridge. Others will open by the summer.
But opponents say bike lanes are adding to the congestion in London and are "politically motivated".
