Proper brakes and tires already exist.

Going 30mph is going 30mph no matter how you attain that speed.

Well, the petroleum is also delivered by truck, takes huge amounts of energy and tremendously toxic chemicals to refine, takes huge amounts of energy to recover from the earth, and produces toxic gases---not oxygen----throughout the process. And the waste from petroleum is toxic in all forms, while the waste from food is fertilizer.

You know, I really appreciate you pointing that out.

The answer is: you might be right!

Remember some time ago, there was a politician who suggested that bikes were no more eco-friendly than cars because cyclists exhaled carbon dioxide? He was roundly criticized and shamed in the social media ... I mean ... who would ever suggest that?

But I got to thinking. Lessee ... me, breathing hard on the way into the office, versus maybe 7 people in a fairly economical minivan. Which produces more CO2 per passenger? I looked it up. The bottom line is that we still produce much less CO2 per person transported than even the most efficient van would. The reason is that the exhaust of the car is almost all CO2 and water. What we exhale is still mostly air with a little bit more CO2 in it. I wish I still had the link, but that was the bottom line.

But that is only CO2 (not all the other stuff like what the environmental cost is in building the bike).

My guess is that how an ebike makes out would depend on how much of the energy is generated by burning fossil fuels versus other sources. The food we eat is of a different class as a source of CO2 than fossil fuels pulled out of the ground (as the growing food scrubs some of it to create oxygen), but as you point out, food does need to be transported and prepared.

Interesting question!

No... "Legal" E-Bike can't go 30 MPH with assist... Even in the USA it's at 28MPH and the "assist" cuts out... Personally I would go with the 32Km/Hr that's 20MPH and with no throttle EU laws, that would be more realistic and more widely excepted by the general bicycling community and people in general, but hey that is JMO...

Interesting question!
Two small counterpoints:
1. The wasted energy on any given trip is going to be proportional to the wasted mass. An e-bike weighs in at 30-60 pounds and a normal bike weighs in at half that. An electric car weighs in at 3000-6000 pounds. The vehicle is all waste, not payload. Heck, the embodied carbon cost of an electric car are so large that a cyclist may never catch up to those in a lifetime of commuting.

2. In order to be healthy, a human needs a minimum of an hour of relatively vigorous exercise per day, not that many Americans manage that. Therefore, I think it is fair to simply subtract that first hour per day of riding from the energy equation. Note that an hour of exercise is much more than an hour of riding a bike or e-bike in most settings since one isn't really exercising while descending (unless it's a long grade of minimal gradient).

It is extremely extremely unlikely that I would bet an e-bike, but if I did I'd like one that the pros use to cheat. And I'd have to install solar panels to charge the battery.

A friend has modified his e-bike to assist to over 40 mph. He said it was easy.

That's what I would do. Maybe not to that extreme, but the biggest advantage I would want from an e-bike is the potentially higher speeds.

A couple days ago, I went for a ride on the local and very flat MUP with my family. A lot of other families had the same idea. We rode by a group of people who had DRIVEN to the path and were unloading their bikes--one of which was a electric motor powered bike. About a mile later, the group with the motor bike came up from behind and the motorbike lady scootered by us on the right and then made a left turn without looking to follow her pedaling friends who had passed appropriately on the left and turned safely. I suspect that this lady drives her car the same selfish way and she continues those habits on her two wheeled motorized vehicle. The electric bike salesman will say that that lady would ride a real bicycle in the same manner. I say, that had she become a member of the cycling community, she would be more courteous and aware of her surroundings. And it really pissed me off that some old lady passed me.

I mostlyride out in farmland north of town. It’s mainly flat. I ride solo and do my 20 – 30 miles at 10MPH. On a certain route there is a hill that I find is too steep for me. I turn 71 on Friday and have no qualms about walking the bike up that hill. The south part of town is hilly and when I go down there I find that if I don’t route my trip with care that there are more hills that I have to walk. If I lived in that area I might consider an e-bike if only to get up the hills. Since I have the option to ride where there are fewer steep hills I don’t ever expect to purchase an e-bike. Not everyone is as fortunate as I am.

One of my fears about ebikes on MUPs is that it would only be a matter of time before an ebiker would be shouting "single file" to me on the bike path. That happened a couple of weeks ago.

Of course, not 10 minutes later, someone without motor assist did essentially the same thing.

Motorized bike or not, people can be arseholes. But I do think that making the jump to a motorized vehicle makes the transition to arseholedom a bit easier. It is a lot easier to be impatient with people going slower than you when you're having a motor doing the work for you.

Yea, I had a debate with someone here on that topic some time ago. They were adamant that modifying an ebike to get more speed is too difficult to be a serious problem.

Then I found there were threads on bikeforums dedicated to just that topic, and that he was an active participant in those threads.

What were you doing that caused two different people to shout “single file” to you while you were riding?

Society was handling it. Mopeds were not allowed on MUPs or in bike lanes. Then industry got involved and had electric mopeds redefined as bicycles. Now we have a problem.

My immediate and initial reaction to e-bikes is negative. In fact, very negative.

I can understand an e-bike could possibly help keep some active who otherwise may not be able to do so by the tradition means of pedaling. Okay, I'll buy that.

Personally, I want to keep the drive to push myself to MAKE myself stay in shape to keep climbing these hills, and the only way to do that is to keep pushing myself to keep climbing these hills and pedaling under my own power.
I could see myself becoming lazy with an e-bike and unwilling to work as hard for the gain and stay in shape, with the result being losing the ability or motivation to keep on keeping on. I rather suspect there are many advocates of the e-bike where that is the motivation...get the benefit without having to work quite as hard for it.
<shrug> Not sure that matters to me or not, nor exactly how I feel about it. All I can control is me.

And so, I think I will resort to what the pros do...

DOPING!!

Hallelujah for Caffeine and ibuprofen!!!
