At the moment one of our TV stations is showing a BBC series called "Lilies", set in Liverpool, England soon after WWI. Essentially it's the story of three sisters in a struggling household. One of them, Ruby, has been filling in for the postman while he's been at war, and uses her postie cycle to go to swimming training - see her in action on the bike on YouTube (about 1 minute into the series and then again riding down the corridor in the post office about a minute later). It's a vintage men's bicycle, and she's bitter when the postie returns and gets his job and bike back.
She then applies for a job selling corsetry; she's less than impressed with the woman interviewing her and almost turns the job down until she discovers it includes a bicycle. The bike in question is a black vintage loop frame single speed bike with (I think) rod brakes and a front basket, and cream/white coat guard. Ruby rides it confidently in her long skirts and louis heeled shoes and boots. It was shown a bit in the first episode but has been absent since. You can find it here on YouTube - at about 4mins 20secs in this clip. Maybe some eagle eyed person out there can identify the make of the bike; I certainly have no idea!
The postie bike got some airtime in this week's episode with the postie giving Ruby's sister May a ride on the front rack; May sat sidesaddle and I was impressed by the ability of the rack to take her weight and the stability of the bike. I suspect, as the panning was careful not to show the postie's face when they rode off, a stunt rider was involved.
Hmm... take it easy, the doc said. YouTube beckons I reckon!
