In recent years a number of extremely diverse tribes, linked only by their love of two wheels, have sprung up around London.
Whether Shoreditch fixie types, yummy mummies on Pashleys or those Darwin's Deli sandwich peddlers, they are all celebrated in a series of new portraits commissioned by the Museum of London.
Created by Ugo Gattoni, the ten drawings form part of London Cycles, a display of historic bikes from the Penny Farthing onwards, right up to today's Boris Bike.
London Cycles is on at The Museum of London between 5 July and 22 September, free admission.
After an unpromising start, having to be bribed by her parents to learn to ride without stabilisers, Sarah became rather keener on cycling in her university years, and was eventually persuaded to upgrade to proper road cycling by the prospect of a shiny red Italian bike, which she promptly destroyed by trapping a pair of knickers in the rear derailleur. Sarah writes about about cycling every weekend on road.cc.
