The sporty pair, who can usually be found in their quarters in north Wales, have taken to riding when in the capital city, where they have a home inside Kensington Palace.
A spokesman for the couple says, "The Duke and Duchess of Cambridge occasionally use the London cycle scheme bicycles to undertake private journeys around London."
Their peddling around was first revealed by the Boris Johnson, London's mayor, on LBC radio.
Barclays Cycle Hire, nicknamed Boris Bikes, was launched in summer 2010 and quickly proved a success, with more than seven million journeys taken from some 400 rental stations across the city.
