The casualty rate is 5604 per billion passenger miles cycling, and 238 per billion passenger miles in a car.

The death rate is 30.9 per billion passenger miles by cycle, and 1.9 per billion passenger miles in a car.

As noted, cyclists have a similar (only slightly lower) risk of casualty to motorcyclists, but much lower risk of death - slightly lower than a pedestrian. This presumably reflects speeds, etc., and does suggest analogies with motorcyclists are not wise.

In terms of 'serious injury' these are about 1/5 of the total for cyclists, i.e. 1120 per billion miles

To put it another way, if you did 52 * 50 mile weekly rides for 20 years with 12 people, that would be 624,000 passenger miles cumulatively, and you would expect to see a SI in that time

Just checking the figures, assuming the 1120 is correct, 1000,0000,000 /1120 = 892,857 passenger miles per SI. Assuming serious head injury to be 40% of injuries, once in 2.232 million miles cycled. Is this near to what would be expected from the data?

This one? (Dutch, btw, "leren fietsen" is "learning to cycle")

At least our culture isn't mad enough to have whole-heartedly embraced the Thudguard for small folk learning to walk. Read the marketing blurb for that and it's remarkably close to how helmets have been pushed on cyclists. I think it's mainly gained traction for bikes because cycling isn't normal any more, and can thus be assumed to be weird and/or dangerous.

That's it. Well done. Lovely happy video
No helmets just kids discovering the joy of cycling.
