Don't worry about it. It will probably be more scared of you than you will be of it. Or it will hear you long before you ever come near it and it will either take off or hide from you. But if you do come into contact with it, make yourself as big as possible. Get off your bike and hold it above your head. If it does leap at you, you should be able to bring the bike between you and it as it leaps or even throw your bike it at. Shout at it and make as much noise as possible.

Or your other option is to quit riding all together. Nothing we do can be guaranteed 100% safe.
