I didn't choose any of the options in the poll because I think they're really lacking.
I wouldn't call myself an "avid" cyclist, but I do cycle often. I live in the city, so my bike is my preferred method of transportation while I'm in the city. I cycle to the pool 3 times a week, and frequently cycle into the city for other reasons. Most of my trips around around 3 km (~2 miles) one way. While I'm in the city, I'll cycle from place to place, so no more than 1 km!! It's great.
I own a Cooper Sebring, and it's a fantastic bike. I only got it 6 months ago, and have really enjoyed the crap out of it.
Everything from the Brooks saddle to the bullhorn. Bullhorns are better than drops, IMO. It's a single-speed, which is just perfect for Melbourne. It is a very FAST bike!!!! The lone gear on this bike is set fairly high, so I think you need to have a fairly high fitness level to ride it. I'm still young, so I can still ride it. I regularly beat the lycra crowd, which must be embarrassing for them. I mean, in the winters here, I'll be wearing jeans, a shirt of some kind, and a down vest on top. Nobody in lycra wants to be passed by a guy on a single-speed wearing a down vest and boots.

My other bike, which I bought 12 months ago, is an Allegro hybrid-style bike with a Shimano 8-speed internal gear hub. It's very comfy, very low maintenance, very convenient, but I haven't rode it since I got my Cooper Sebring!!
