I'm really sorry to hear that.

Bikes CAN hurt pedestrians, but it's statistically rare compared to injuries/death caused by cars. E-bikes increase the risk significantly, though.

It also illustrates that proper infrastructure is needed, since an accident like that shouldn't even happen. In some areas around here, we have split trails, which separate (by several meters and bushes) cyclists and pedestrians.

However, there are often pedestrians strolling on the cyclist side, or cyclists on the pedestrian side, and that's just dangerous for everyone. I honestly don't know why simple routes are so difficult for some people to follow.
