There's longish waits for many bike models at the moment Alan, the pandemic (and specifically lockdowns) did two major things to affect bike supply in 2020: They pushed demand for bikes higher than ever, and secondly, they closed down some of the major component factories for months, putting the supply chain for assembly under previously unknown pressure. That's still having a knock on effect.
It's getting better but the supply issue endures... I wanted a particular Trek (children's model) in the last few weeks and of the exact colour I wanted, there were only two in stock the UK. Some retailers were offering one for delivery in July. So it really is a case of looking hard and maybe travelling a long way for a specific bike, or going on a waiting list. As Cycleops says, choosing a different, more easily available model can work, but even that can be tricky.
