I brought my bike in Easter 2012 and am sure it was a lifetime guarantee on the frame.
There is now an unbearable creaking sound (and possibly dangerous) fault to the frame. Have taken it to Decathlon in MK who told me there is only a 5 year guarantee, but I can see on your website this is only from 2013.
Can you please advise what I can do. I have always brought Btwin bikes
