My recent claim has now been settled, very pleased with how it was handled, so I recommend AA very highly! It was a week past Thursday that I submitted full information to them so that is just over a week to fully sort! I was offered the option of a replacement bike for one of the stolen ones, which I declined as I would rather buy locally, they offered me full cash value, no nonsense about trying to offer me their discounted price, nor did they try to force a replacement on me. On the other one they admitted that they would struggle to replace directly therefore just offered me cash.
Overall very pleased and would highly recommend- I am with the AA though they are just a broker (though I think it is the AA policy that is good for bikes, not the individual insurers, if that make sense), my policy is with Allianz and it was them I had to deal with, they were polite, helpful and friendly. Allianz also use a 3rd party, homeserve, to value your claims, again they were polite, helpful and friendly in my dealings with them. They also seemed to have a good enough knowledge about bikes to have a reasonably discussion with them about what was and wasnt reasonable in terms of replacement.
Overall 2 thumbs up from me, if you are looking for insurance for your bikes I would definetely recommend checking out the AA
