My prior comment on hydrogen mobility:
Hydrogen for mass- or space-constrained mobility (eg bikes, automobile, aircraft) faces all the known problems with storing it inside inconvenient shapes and contending with the losses from liquification. Real Engineering has a video on this aspect (Nebula and YouTube) when compared to simply using battery-electric storage.
With that out of the way, my takeaway from this article is that manufacturers are working on broadening the appeal of bikes and micromobility with new models, be it harkening to the classic "Dutch bike" or designing for less smooth surfaces. Some are clearly gimmicks and fads, or advance the surveillance state. But by and large, innovation is taking place, proof that this market will not stand still for even a moment.
