So me and Timmy went to gym s'morning for a mega cycle. After a third of the distance I paused for too long trying to sort out my headphones and it stopped. So Timmy took the key over signed me out and in again. I did another third of a cycle and got fed up and left.
We did realise that as GGtGG had put the FES on the back of my knees without enuf springyness that was why it was hurting my knee, so Timmy will try a replacement later
