I would speak to the insurers and find out how they would manage a claim. I had 2 different experiences with the same insurance company 8 months apart. (Sainsbury’s underwritten by Halifax- they let you specify bikes and pay a bit more and have paid out twice: shed theft and stolen from locked Thule roofrack).
The first time I had nominally insured for £2000 (one of several stolen). Claims investigator came out the check story documents etc. Wheelies then checked out details of bike and upgrades added, etc and said I could spend £3500 in their shop (or 75% as cash still more than the 2000 i had it listed for- a whole different argument about having to use their shop though, I know). I checked- “Are you sure, I only had it insured for £2000?… er ok then!”
The second time I had insured exdemo bike for the price I paid plus upgrades (also £2000) and this time, despite the fact that to replace the bike would cost more, they would give me that as a maximum payout for Wheelies or anywhere else. But they never took either the police crime number or copy receipt!
So… check how they’d handle a claim would be my advice.
