It’s an interesting result but needs to be studied much more. The amount of ebike crashes is tiny, despite the researchers claiming it’s statistically significant.
My biggest problem is that it doesn’t make any sense.
“The researchers analysed 686 crashes involving e-scooterists and 35 involving e-cyclists.”
To ascertain the statistical significance of the findings, we calculated the 95% confidence intervals and p-values (Lash et al., 2021). The statistical significance level was set to α = 0.05.
Yea how does that make any sense? How are 20x more crashes, the safer option? Severity of crash? How do they compare that?
I assume it’s because there are that many more scooters than bisycles on the road, but how can you even begin to argue 35 bicycle crashes across multiple cities across multiple years had any statistical significance?

From the article:
“The high number of crashes involving e-scooters reflects that they were used much more frequently than e-bicycles”
They really shouldn’t frame it as “number of crashes” and put it into crashes per 1000 ridden km, or something like that. At least for the layperson.
Edit. I assume it’s because there are that many more scooters than bisycles on the road, but how can you even begin to argue 35 bicycle crashes across multiple cities across multiple years had any statistical significance?
Exactly that. 35 is nothing, especially when they don’t result in fatalities.
