It’s like, you are a meat bag with a fragile coconut head traveling at least 25mph, like, please read the Humpty Dumpty story.
35 is hauling pretty good ass on a bike. It's not a speed it'd be advisable for someone to just jump on a e-bike and do. Fortunately, most e-bikes made by reputable manufacturers top out at 20 or 28. Unfortunately, there are plenty of less reputable brands. Not that nobody can ride faster safely, but this is a case where earning your speed will give you the experience to manage it safely.
[0] Before they pivoted to the larger and more lucrative stroller market, they made excellent single wheel bicycle trailers for touring.
Friends wife went for a walk on a pedestrian path, onlookers saw her hit from behind by someone on an e-bike going very fast. She still doesn’t remember anything.
/r/IdiotsInCars is a monument to how ineffective permitting is for this purpose. The people rear-ending pedestrians on sidewalks at 20MPH might be the same people who never miss their off ramp.
Maybe.
There are regulations, but the wording is generally such that the bike cannot be sold with a speed capability greater than X. So the bikes ship from the factory with a firmware setting for the max speed of X. But as soon as people buy the bike they go into the bike settings (!) and change it to whatever higher speed that they want.
Whenever crashes happen these settings need to be examined and they need to be part of the liability determination.
It doesn't show you if it would happen any less compared to no permitting.
Not that I care either way regarding permitting, but people being stupid is common, but we still do things to try to limit it.
Without an ebike you gas out and decide not to go back up.
Do you get 2x more trips down the hill? 3x? Probably depends on your fitness level.
As an intermediate rider one reason I’ve not gotten an ebike is I worry that it increases my exposure to the more dangerous parts of the sport.
