I agree, there are a lot of E-Bikes in that film clip.
The news clip doesn't differentiate between pedal bikes and e-bikes being involved with the accidents.
So, considering safety is important. And, it is more than just strapping on a skull cap.
I like the idea of safety training for young riders (or any new riders).
One thing I've wondered about e-bikes is if they are able to sneak up on vehicle's right side. So, say if I drive 1/2 mile on a road, I'll know if I've passed any bicycles before making a right hand turn at a stop light. On the other hand, if an e-bike is cruising 30 to 40 MPH up the bike lane, then passing on the right, it is possible they could sneak up and be missed.
