Ebikes, bicycles, scooters, skateboards, longboards, eboards, motorcycles, skates, unicycles: Whatever floats your goat, this is all things micromobility!
"Transportation using lightweight vehicles such as bicycles or scooters, especially electric ones that may be borrowed as part of a self-service rental program in which people rent vehicles for short-term use within a town or city.
micromobility is seen as a potential solution to moving people more efficiently around cities"

It's a little sad that we need to actually say this, but:
Don't be an asshole or you will be permanently banned.
Respectful debate is totally OK, criticizing a product is fine, but being verbally abusive will not be tolerated.
Focus on discussing the idea, not attacking the person.

They don’t mention the range. It seems like it would be hard to beat current battery energy density on a motorcycle with hydrogen.
You don't really have to beat battery energy density to be better for longer range riding, you just have to have a minimum acceptable range and the ability to quickly refuel. For example having to stop every 100km for five minutes is likely going to be more acceptable to the majority than stopping every 200km for an hour.
Of course the real trick is to both figure out how far the minimum distance is for most people and - most importantly - making refuelling widely enough available that people can work on the assumption of just pulling in and filling up.
If we have to refuel more often, or if we have to recharge longer, we're still gonna need better rest areas on freeways in both scenarios.
It would also allow to do a small afternoon tour, e.g. jumping on the bike and going 200-300 km through nature just to chill, and then back home. Right now this means a 1 min break at a petrol station, as commonly after 200-250 km you have to refill.
With battery bikes and data sheet ranges of 'up to' 180 km, with 70 kg passenger at constant 45 km/h, you probably get to 20% charge after 80 km already to recharge to 80% within an hour. So after an hour waiting you just get enough to barely make it back home.
As you say, with hydrogen it would allow for shorter breaks, enabling to do a small afternoon tour at all. And I'm not that stingy about a 1min or 5min break to refill.
