They came and they took it away
I was left with another Agility 50 on a slightly newer plate, while they take mine to look at.
I did a couple of journeys on it and, I want mine back. It has a few faults, which is to be expected as a courtesy bike. The main ones are the back break is either off or lever in as far as possible and fully on. The headlight doesn't work properly, I had to ride home 5 miles using side lights or high beam. It does seem to pick up speed better and definitely starts easier.
I guess I can't feel the bike as much, which doesn't leave me with lots of confidence in it.
Hopefully I won't have to wait too long until I get mine back in running order.
