Something similar has happened to me - and a great deal of power lies with the insurance company - I'm not sure what you could say to them to change their tack and offer you full value.
You could try negotiating with them. Maybe because you haven't claimed for personal injury you may be able to convince them to pay up in full now for the bike rather than face a protracted PI case.
Also - and this is a bit off radar - they may not be willing / able to take posession of the damaged bike, so you may end up keeping that, too, and making up your losses by flogging the undamaged parts. This is common, but it's not great, as technically it doesn't belong to you, but as above the insurers probably won't take posession.
Another approach would be to ask them to simply replace the bike, like for like, which I'd imagine would cost them a great deal less than it would you.
Depends if you want an easy life or not.
