My recumbent stable is two single bikes that I ride and a shared tandem that we ride. Plus a 'bent frameset that will at some point either be sold or built up to ride again. Plus a Novara Big Buzz hybrid from my pre-'bent days hanging forlornly in a corner of the garage that at some point may end up with a son or sold.
I firmly believe that you gotta have a Backup Bike. At least. But Too Many Bikes can be a burden.
