Funny bicycle shop name: "N+1 Bikes" (https://n1bikes.com/)
Unfortunately (or luckily, depending on the point of view 😉) they mostly seem to have mountain bikes and nothing really fancy like folding bikes, recumbents, trikes, tandems, etc. 😇
In other news: I recently noticed that the n+1 rule also applies to #mechanicalkeyboards: I'm eagerly awaiting @thpoll's #polykbd becoming available for preorder at https://www.crowdsupply.com/polykybd/polykybd 😁
