None in the house - none of them are house-trained enough to be trusted not to leave tell-tale black chain-link-shaped marks on the carpet.
(On VERY special occasions, i.e. when I'm off at silly o'clock in the morning, and don't want to wake the neighbours by opening the garage door then, the Brommie is allowed in the hall, if folded.)
7 in the garage. (2 'bents, '80s-style Peugeot racer, Super Galaxy, Discovery Twin tandem, Ridgeback Nemesis commuter, Brompton.) And a trailer. No room for a car.
Only me in the house.
