I currently have three bicycles. I've owned, including my current bicycles, seven in the last three years, so I'm hoping to keep my collection somewhat stable over the next couple of years at least. Even then, the only one with real possibility of replacement in the near future is my beater, and that would be replacement, not addition. I was toying with the idea of a mountain bike in the last month or two, but I've decided that, not only do I not have the space or time for a MTB, but that my current low-mileage lifestyle doesn't really justify yet another bicycle. I'm planning to start hitting the roads a lot more frequently this spring and summer! Anyway, my bicycles:

1) 2006 Surly Long Haul Trucker - My main commuter and utility ride, also intended for long-distance rides and loaded touring. This is pretty much the do-everything bike.
2) 1987 Univega Gran Record - A speedy little late 80's road bike. It's not a super lightweight, at about 24lbs, but this is my go-fast, have-fun bike. It's a blast to ride, but also tiring!
3) 1978 Schwinn LeTour III - This is my beater and project bike. It's been through four builds in the last year or so, and I'm pretty settled on the present singlespeed configuration, with a semi-upright seating position and nice, swept upright handlebars. This one is very popular with almost everyone who sees it! The only original components are the seatpost, front brake and headset.
