It doesn't really exist, it's only in my head, but....
Imagine a bike shop you could own, what type of bikes would you stock? What else would you stock?
These are my thoughts:
1: A good range of folding bike brands : Bike Friday, Moulton, Birdy, Dahon and Pacific, at least one example of each model for each brand.
2: Bikes with Rohloff, Shimano Nexus, Sram iMotion and Dual Drive 3x9 and Sturmey Archer 8 hubs for the IGH fans to test and a fully trained IGH bike mechanic to fix them, also seperate hubs for sale.
3: Large choice of quality rims, tyres, tubes and spokes for 16,17,18, 20 & 24" sizes.
4: A small museum of classic folders like the R20 in standard form and modded, maybe even workshops showing customers how to build up and restore bikes, even brazing and welding lessons.
5: Pannier racks for all sizes and Ortlieb, Arkel etc panniers
6: Tandem bikes, full size and 20" for touring, racing and recreational use.
7: Touring bikes.
8: Camping gear, specific to bicycle touring.
9: BoB trailers.
10: Most important: Staff who have a passion for these bikes, mechanics who want to fix your bike properly and back up service that's legendary.
Did I leave anything out?
