Ok as a Wulfrunian (a Wolverhamptoner)... I remember Poyners bike shop from when I was a kid. It was based on Dudley Road (basically the main road from Wolverhampton to Dudlayyyyyyyyy). They seemed to always compete with Fred Williams bikes (still going strong) and Mike Stallards (son of Percy Stallard).
Wolverhampton was once a bit of a hotbed of bike manufacturers. Sadly there is very little left of that in the town.
Heres a list of all the bike manufacturers we had in Wolverhampton once (strangely it doesnt list Poyners as one as I think the list is just factories rather than shops) - http://www.localhistory.scit.wlv.ac.uk/Museum/Transport/bicycles/makers.htm
