A special exhibition to mark the start of the 2014 Tour de France in Yorkshire will be held at Cusworth Hall Museum.
It will look at all things cycling and celebrate that proud childhood milestone of the first bike.
Doncaster Museum Service is asking people to send in images of themselves with their first bike, or to contact them if they have an interesting bike, or cycle-related memorabilia, which they might be willing to lend for display.
Coun Bob Johnson, Cabinet Member for culture and tourism, said: “This exhibition will coincide with the world’s greatest cycle race and next year is set to be the best yet as The Grand Départ 2014 is in Yorkshire.
“I hope people will take up the invitation to share images of themselves with their first bikes – whether it is a sparkling Raleigh Chopper, a rusty old hand-me-down or a state of the art BMX bike.”
