I've had little kids shake off their mom's hand and run right in front of my human powered bike - I had to lay my bike down once to avoid hitting a little kid, and I was only going 14 mph. Dogs and kids are incredibly unpredictable and just when you think they are controlled, they are not. I cannot imagine how I would have avoided hitting that kid if I had been going more than 20mph. At the very least my slide would have taken me right into the kid given the added speed and weight of an e-bike. I'm not saying the problem is the e-bike or the motor, but the speed increases in unpredictable settings can increase accidents. I always slow down and hover over my brakes now when I pass around kids and animals.
