I've bought and sold quite a few bikes over the years, but seem to always have at least five or six on hand. Here's the current lineup:

Mine
- Cinelli Vigorelli Road... Cro-mo steel frame, carbon fork, rim brakes, drop bar, 2x11 drive
- All City Nature Boy Disc... Cro-mo steel frame and fork, mechanical disc brakes, flat bar, single speed (technically 2-speed, but I can't shift while riding; it involves a tool and takes about 60 seconds)
- Surly Steamroller... Cro-mo steel frame and fork, rim brake on the front only, riser bar, fixed gear
- Cinelli/Mash Parallax... 7075 aluminum frame, carbon fork, rim brake on front only, bull horn bar, fixed gear
- Takara... Hi-ten steel frame and fork, rim brakes, riser bar, originally a 2x6 but now converted to 3-speed IGH

My wife's
- Trek FX3... aluminum frame and carbon fork, hydraulic disc brakes, riser bar, 3x9 drive
- Schwinn something MTB... steel frame and fork, rim brakes, riser bar, retrofitted as e-bike with 1x7 drive + 750W motor

My son's
- Specialized StumpJumper (rigid 1991 model)... Cro-mo frame and fork, rim brakes, riser bar, 3x7 drive
