Well, don't stick around long enough to see a recation. Like any living thing, when attacked, they will attempt to defend; thus bite you.
If you were walking, jogging or riding a bike slowly, there is a distinct possibility that you would get bit. If the snake has the ability to coil a bit and launch itself, it can travel vry quickly for a few feet. Of course, having a bike tire parked in the middle of it's back will limit that distance a bit (you hope).
Rule of thumb, stay clear. Should you get bitten, relax and call for help. Don't do anything to make your blood flow faster. You'll live through any bite, but you won't be terribly comfortable for a while.
