Tomorrow's Bargain Hunt will feature a visit by the programme's presenter to the National Cycle Museum of Llandrindod Wells.
Charlie Ross introduces the show from the Royal Welsh Showground in Builth Wells but then "gets in the saddle and finds out about a weird and wonderful collection of bicycles," says the BBC.
In the photo above, the museum historian Scotford Lawrence is shown discussing an Itera plastic bicycle with Ross.
Footage for the BBC antiques show was shot in September last year. The programme airs on Friday at 12.15.pm.
