The email does sound a little sketchy. But if you get the money in the paypal and it is marked as clear from paypal then you should be fine. Although the person can send the money, it will be cleared and then once they receive the item, they can make a fraud case and if you dont have any proof besides your word that she received the item, she will win and you will be shit put of luck. Soo you have to make/have hard proof that she received it. Like fax her documentations saying the whole story, then have her sign it and fax it back. Then get the delivery person to sign a document too and what not. You just have to make sure that if she tries to screw you over, that you have hard proof about the agreement that was made and what not. Also get the back on video working and the condition it is in, saying your name, date and details about the bike. Just get as much evidence and more info about the lady before you make the deal.
thats what i was worried about, the fraud case, but il definitly do those things, thanks man
edit* and what if she signs a fake name?
