A british company had a hydrogen fuel cell bike prototype a few years back, not sure what came of it. Design looked pretty ugly/basic but it is interesting. They said it could topout at 80. I dunno what the bike in that video can get to but I'd think < 50.
It's a cool idea but there is just no hydrogen infrastructure setup.
HOG has the livewire EV that they've let people test drive and put it in show rooms. Gotta be careful with that since it can reach full torque instantly. No gears, just all throttle management.
