I think it's more complicated - a pedestrian could easily have more KE than a cyclist (e.g. 80kg geezer runs across road, hits slight rider queueing at a red light.)
Also vulnerability is complex - elderly rider at 8mph is quite vulnerable. 100kg 25yo male pedestrian weaving off the pavement is less so.
(Much harder to find similar examples with a motor vehicle.)
Lots of variables :-/
