One mile from my house:

While most ebikes on the road today will come with a battery pack, some are riding down the hydrogen fuel-cell cycle path. HydroRide not only has fuel-cell ebikes available, but also a compact refill station to top up H2 canisters. The global ebike market is estimated to grow in value to almost US$120 billion by 2030, and it's not surprising. Whether commuting or leisure riding, pedal-assist bikes take some of the strain out of the journey while also opening up routes for older riders. The vast majority of ebikes on the street roll with Li-ion batteries, but they can spend a good deal of time parked up charging, Swiss tech company HydroRide Europe AG is hoping to tempt e-cyclists over to the hydrogen fuel cell camp with the promise of super-fast top-ups for its range of city ebikes. And even has a compact hydrogen generator in its product portfolio, which can produce 20 g of hydrogen from 200 ml of purified water in around five-to-six hours. The company says that its refill station can even be powered by solar panels instead of the grid to produce green hydrogen, though efficiency and operational figures don't appear to have been revealed.

To me, e-bikes are just electric mopeds.
It depends of the are pedal assist or not. If they are pedal.assist, you must pedal through the entire ride it quits on you.
The ones that you don’t have to.pedal all the time are classified as scooters and mopeds and they have different laws.
On my bike, although I do have to.pedal, the e-motor does most of the work until 26km/hr. Then it forces me to.increase my load accordingly.
Water vapor condenses pretty quickly (a few days), I don’t think human emissions of water vapor are or will ever be significant to climate for that reason. CO2 lasts decades I think, although eventually it is absorbed by the ocean.
At least they won’t be burning up they’ll just blowup.
That’s the reputation of hydrogen, but testing shows the hydrogen just evaporates in the event of a kinetic event.
14 MPH is something you can walk? That’s a bit over a four minute mile. Good for you.
If you left it outdoors, you were safe. But park it in an enclosed space and in a while the leak builds the nat-gas concentration up until something as otherwise benign as flipping a light switch or starting the garage-door opener spreads your house over half a city block. At the very least anyone who owns such a conveyance and parks it inside should install a fuel-gas detector near it with a very loud alarm. These will alert you long before the smell of mercaptan does. (Hydrogen of course has no odor.)

“At least they won’t be burning up they’ll just blowup.”
Did you sleep through 9th grade science class?
What bikes do you have? Mine don’t have those problems. Plus mine have brakes.
“H2 under high pressure. Enough volume at 1 bar to create a home-made thermobaric bomb when mixed with the ambient air.”
You don’t know what you are talking about!
You may have worked with hydrogen but I challenge (AGAIN) you to show numbers to support your post.
I see a lot of people riding them at speed, and they aren’t pedaling!
In Canada, bikes must be pedal assisted to be considered a bicycle. It could be your local ordinances.
What bikes do you have? Mine don’t have those problems. Plus mine have brakes.
I am sorry to have confused you to the point where you believe that my brand-new folding e-bike or the mountain bike that I recently installed a brand-new electrification kit on do not have brakes.
As someone who once competed as a bicycle racer at a national level and has a lot of experience riding in groups ... I was noting that the e-bikes that I ride do not have the very precise speed control that is necessary when riding in very close proximity to others. This is something that may be outside of your experience.
As far as the e-bikes that I have... they are mentioned in detail in my previous posts, including pictures. I also noted that I know of others with expensive road bikes that have been converted with equipment that is higher in quality than what I have.
Oh, yes I do. Seen the results of letting hydrogen loose in a confined space first hand. Any high school chemistry student understands this.
6th grade science class we made hydrogen in a test tube using a 12v car battery charger, test tube and a container of water. Teacher lit a bic lighter after a few minutes and pulled the test tube mouth out of the water..FLASH BANG!!!
“Oh, yes I do. Seen the results of letting hydrogen loose in a confined space first hand. Any high school chemistry student understands this.”
Show the numbers! Or did you also fail 8th grade math?
I worked as a Hazmat Officer for many years... What you imagine is unrealistic. Hydrogen has its risks obviously, but because it is extremely light as compared to the oxygen, nitrogen and water vapor that makes up 99% of our atmosphere, hydrogen dissipates extremely quickly. There is virtually no chance that a hydrogen leak even from a high-pressure source would result in anything resembling a thermobaric bomb.
The natural gas and propane leaks that cause structures to blow up are because of explosive mixtures contained within enclosed spaces.
Hydrogen has been used as a fuel for vehicles for many years. Here is a video explaining why explosions are extremely rare.

Hydrogen rises so quickly in the atmosphere that even most of the radiant heat goes up. When I was a kid my friends and I made hydrogen balloons by putting a balloon on top of a bottle with aluminum foil dropped in a strong lye solution. We would sometimes light one on fire while holding it in our hands. It was impressive at times but I do not remember ever getting burned because nearly all the heat went straight up.
