But they are quite cheap and they fold away. The next tier up 'wheel-off' trainers are much quieter. But you've still got all that faff (add chain oil to the mix when taking the rear wheel off) of getting the bike upstairs, the wheel off, mat down (for the sweat), positition the fan etc. But I don't have a load of space so a dedicated exercise bike is a complete no. By the way, clip the resistance switcher on the top of your front wheel rather than your handle bars. Fits well there and is out of the way but still reachable.
