Once you have a road, cross, gravel, fixie, hardtail, dual suspension, TT, hybrid, cruiser, fat bike, tandem and house bike* you should be all set though maybe you want to distinguish between a performance and endurance road bike but after that what's the point of a spare?
*Wife's term meaning the retired road bike that is permenantly relegated to trainer duty
