Yesterday I used the exercise bike for 55 mins. What an idiot. My ankle let me know afterwards that that was a bad idea.
Today, to make matters even worse, today I find that the bike is broken!!! After dismantling the wheel and having a look, the only solution is to take it back to Argos and try for a refund/replacement. It's only been used for about 10 hours over 16 days - surely it should be able to cope with that.
