I don't see any moral obligation on your part to pay anything. Different story if he had lent you the bike and something broke while you were riding, that would = 100% liability for you. When you're trading and riding together with no abuse on your part, I'd say 0% for you.
The other issue is financial - If you've got lots more cash than your friend, no problem helping him out - them that has, pays!
