6 for me kind of

29er full squish mtn bike that I ride a lot
29er rigid mtn bike that I haven't ridden a lot this year but probably will start riding more often this winter
27.5 slack hardtail mtn bike that I just bought and love sofar, might make riding the rigid more unlikely this winter
26er hardtail was my first real bike and isn't worth anything so I keep it round. I keep fixing it back up thinking I'll ride it, ride it once then end up stealing a part of of it to keep one of the other bikes running
26er full squish that isn't really mine but lives at my house and hasn't been touched by it's real owner in 2 years. Has a dead rear shock so I haven't ridden it. Stolen some parts off it too
road bike for those rare occasions were I feel up to risking my life by riding on the road.
