I think places like bike shops are less of a retail destination than they used to be in the internet age. When I was a youngster, if you were considering buying a bike, you made a special trip to the bike shop to browse the wares, most likely on a Saturday morning. Even if you only wanted a catalogue to peruse at home later, you still had to physically visit the shop to get it. Nowadays I bet most potential buyers first port of call is the internet, where they will trawl forums and places like YouTube for reviews, and will also search for the lowest priced source online.
I do get the difference between a bike shop and a shop that sells bikes. What I would regard as a proper bike shop is one where the place was jam-packed with as many bikes as would physically fit, and you'd have a glass-fronted counter down one side with all sorts of components & accessories on display, plus loads of stuff hanging up behind the counter on the wall and from the ceiling. You could see exactly what stuff the shop had in stock, and the staff knew exactly where everything was kept, even down to the most obscure part. You walked in with a duff part in hand and said "I need a new one of these", and you were on your way in minutes with exactly what you came in for. No messing around searching for stock details on computers or disappearing for ten minutes out the back somewhere to try and locate the product.
