A person who buys stolen property has no legal title to it. You certainly have a valid claim to the parts of the bike that you bought. The other person could only have a right to the new bits on the bike.
The Police Property Act is a way of getting it back. http://www.ukpolicelawblog.com/2013/05/08/retaining-property-a-legal-minefield/
You won't get costs in the small claims court so employing a lawyer will not be cost effective. Good luck
