As much as I appreciate the freedom e-bikes provide to people who wouldn't otherwise venture outside, without proper cycling infrastructure, e-bikes are quickly becoming a serious hazard to pedestrians. As a long-time runner who is usually struck by at least one cyclist on the sidewalk per year, e-bikes are in a completely different class. The other day, a kid on an e-bike was careening down a bridge while my kids and I were running up. I'm a decent judge of speed, and the cyclist was definitely going over 40 km/h with dog walkers and other children nearby. I didn't do the math, but that's a great deal of kinetic energy to transfer to a pedestrian (I assume e-bikes are heavier, and most cyclists going that fast are dedicated cyclists on the road). I caught up to another e-bike at a stop light and asked him why he wasn't on the road, "Too dangerous," was his answer - sadly typical. A non-trivial number of cyclists are adopting the "Uber" mindset - break the law until laws or infrastructure changes, but with complete disregard for fellow citizens in the meantime. I've expressed my concerns several times on local biking forums (when a "cycling on the sidewalk doesn't hurt anyone" message is raised)- it's usually met with ridicule, anger and disbelief, but I experience it practically every day.
