Back when I was a lad (early eighties), I used to go swimming at Yearsley swimming pool, which is next to the Rowntree's factory. There was a massive parking area for bikes next to the swimming pool for workers at the factory. It was always crammed full of bikes, and at shift change time the roads would be full of people on bikes going home.
It's a car park now, and the space that used to be so full so bikes might park about 20 cars in it.
