Thanks. I did think about the turbo option. I've already got a fairly decent road bike which I use for all occasions (including commuting throughout the year). I borrowed a cheap turbo trainer and set it up in my shed but it was really noisy and difficult to get the resistance right. I reckoned the advantages of a fixed indoor trainer would be (1) I don't need to keep fitting/removing the bike to/from the trainer on a daily basis (especially given that the bike can get quite mucky during the winter commutes, and I thought a turbo trainer required a specific type of rear tyre?), and (2) I have read in a few places that indoor bikes are much quieter than turbo trainers, which is an important factor for me.
Does anyone have any comments about the noise generated from a turbo versus an indoor bike?
Thanks in advance,
