a trick that motorcyclists use is to slow down a little. the dog
will time and aim their approach at your slow speed. when they're
fairly close, speed up then. the dog won't be able to adjust in
time.

As a motorcyclist off and on for fifty years, I'd say you left out a
step.

When the dog approaches, brake sharply to get behind him. THEN speed
up, planting a large boot on his butt. I've never had to do it
twice.

On a bicycle, with my shoes clipped into the pedals, doing that would
require more dexterity than I can muster.


That's what the pump is for. Works just as good as a boot.
