Can anyone recommend a good but cheap exercise bike

[Loveweekends10]

Looking for a low cost exercise bike ( as a starter) if all goes well I may upgrade later.
Have been looking at the Argos sale ones. Has anyone got one they can recommend?

Not got a make to recommend but it's the sort of thing people are always selling. Facebook for sale locally is likely to have one or people likely to respond if you pop a wanted post on. I got a three hundred pound treadmill for forty pounds this way. At least then you know if you will get use of it without spending to much.
