Help!

Hi everyone.

I'm sorry that my first post here is one of frustration and a request for help but my Mountain Bike was stolen from W9 in London either last night or the early hours of this morning...

Basically my brother gave me this bike so I have no details about it. No make, model, approx. cost etc.

I need to claim on insurance to get a new bike so I can cycle to work instead of taking the always dire and depressing London Underground... but cannot do that unless I can provide them with make, model and approx. price...

Please, if anyone knows the make, model or price of this bike or any websites I can visit to obtain this information I'd greatly appreciate it.
