H2 is dead.
Almost as dead as this thread, buried as it is under pages of arguing about topics not even tangentially related to E-bikes.
Which seems regrettable to me, since it's unlikely that any future visitor will have the patience to wade through 27 pages of unrelated arguments, to find the very few posts actually about electric bicycles.
As every politician knows, the best way to kill an initiative is not to argue against it, but to bury it under unrelated BS, to fillibuster.
Maybe those folks wanting to read about electric bicycles will be better served by searching through these threads on hydrogen fuel:

Bicycles are THE most energy efficient method of transportation, often said to be the most efficient machine man has ever created. Brushless DC motors are very efficient in their own right, robust and versatile, with a high power to weight ratio. Together, they create what is in my view, a very interesting transportation solution.
Look at a representative sample of what is available in mountainbike motors in 2021:
Mfg Model Torque (N-M) Weight (kg)
Bosch Performance Line CX 85 2.79
Brose Drive S Mag 90 2.98
FAZUA Ride 50 Evation 55 1.92
SACHS RS 110 3.66
Shimano EP8 85 2.57
Specialized SL 1.1 35 1.95
TQ HPR 120 S 120 3.90
Yamaha PW-X2 80 3.06
