Yes, they’re covered, but if you have to make a claim on a bike they won’t pay out what they cost you. Bikes depreciate and you could lose hundreds, even thousands.
If any of them are a few years old (mine is over 8 years old) they’ll reduce the payout for wear and tear to a point where, including your excess, it’s not worth claiming and you’ve effectively been paying for nothing.
That’s the thing with insurance – you have a choice of buying it, or self-insuring. It boils down to what you want, the risk you’re willing to take, or can afford and we’re all different.
I have a bike that initially cost me over £2600 and I’ve spent £100s over the years upgrading components. If it gets stolen I want to be able to replace it with a similar bike. If I insured with the AA I’d be lucky to get enough to buy an Apollo from Halfords. My situation is not unique.
The bottom line is, people need information to be able to make an informed choice. Many, if not most, people don’t read all the documentation accompanying a policy, or simply miss parts. They just see the premium and click buy. So making sure people know some companys, e.g. the AA, deduct £££ for wear & tear, is very important. If they then use them, great. 🙂
