Two. About to give birth to number 3..... with my wallet.

1) Touring bike. All around commuter and recreational bike.
2) POS Huffy MTB. About to make it to the scrap heap
3) Roadie of undetermined model and make. To be determined in the next month.

Edit:
If I can count my entire house:
1 more for my wife.
1 Tricycle for the kid
1 Regular bike for the kid.
