It's going to be significantly less tire dust, they weigh a 100th the weight.

Ebikes won't be mainstream in a typical American city though, the distances between home, goods and services and work are usually too great and cars are basically baked into the culture. Better mass transit and bikes for those living in denser cities, is likely America's only good option.

I don't think e-bikes are unsafe though, their lack of safety is dominantly because of cars, and infrastructure not being set up for cycling.

If you use an ebike, wait until you go down by yourself and tell me what you think again. No cars needed. On a cyclist lane. Just you and your bike. If you use it for everyday commute, it's a matter of time. When it happens, it will be no fun.

I just fell a few weeks ago. Some ripped jeans and road rash but I'm ok. No doctor visit required. Low-speed accidents are far less injurious than the sort of high-speed ones you can get into with automobiles, and by far less fatal.

According to WSDOT, there were 2 bicycle-related fatalities in Washington state in all of 2023, vs. 218 automobile-related fatalities. So a 100x difference. The data is there if you care to look for it.

If you care, you'd extrapolate the 2 fatalities to how many would be if bikes were adopted in mass as a means of transport in the Washington state (comparably to cars).

The number of bike trips will not increase by 100x only, certainly by orders of magnitude more than that.

Now multiply the 2 fatalities considering 10,000x or even more bike trips...

OK, let's take a look at traffic fatalities in Denmark (where bicycles are the primary means of transport in most cities). 25 bicycle fatalities, compared to 64 auto fatalities. It's a much closer margin, but bicycles still win out. The statistics are similar in The Netherlands, where bicycles are equally popular.

How many kilometers cycled and driven?

I find it very dubious to assume that cars drive the same amount of kilometers as bikes in the Netherlands...

You can measure mixed risk like this in hours exposed, since the outcome of a car and bike trip in Denmark is the same (you get to work or whatever). That will also be fairer to cars, since I suspect there are more deaths per KM for cars.

I ride my bike just shy of 40kms per commute, the same amount I would drive.

I have been in one commuting accident, plenty of non-commuting accidents though (mountain biking etc.), but you can also fall down stairs while walking or slip up in the rain. We can't be shrinkwrapped everywhere we go. I just picked up my bike, said bummer that hurt, and kept going.

Compare that painful inconvenience to a car accident and it's just silly to call an e-bike dangerous.

I have been in 4 car accidents, and am lucky to be here. You step out from a totalled car, and see the carnage, distress and mess that everyone is now subject to. Traffic has to be redirected, cops show up to take down details of those still alive, EMTs try to find the ways you've been contorted, firemen have to disable the vehicle and clear any fuel and fire risk, the tow trucks scrape the husks of twisted metal off the street so people can use the road again. It's a whole ordeal, and regularly fatal.

Although there are exceptions, usually bike accidents are only fatal when a car was involved. Cars are not safe and never have been, we just accept the risk for the convenience.

The question is not "doesn't the alternative have the same problem in kind"? It's "does the alternative have the same problem to the same degree?" Certainly, bikes have tires too, but bikes weigh a tiny fraction of an automobile, have half the number of tires, and generate a tiny fraction of the dust, per unit distance. We can't let perfect be the enemy of significantly better.

> I don't think this can be a mainstream public transport solution if we want to move forward.

The cities of Copenhagen and Amsterdam beg to differ. Bicycles are first-class citizens there in terms of transport.

> Ebikes are unsafe, for starters.

Do you have any stats on that?

Really, you need stats to realize that an automobile is safer than bikes?

Bike have half the number of tires but remember that they carry 1/5 the number of people. For one person, fine, but families? Good luck selling it... They're also problematic when it rains or snows. Or when the sun is hot.
