That sounds good Mr Coffee but I was looking for improvements in weight and range? Which format will bring us a light bike that goes all day?
I have started carrying 3 (sometimes 4 ) powerpacks on long hilly trips . My bike is solid and comfortable with fat knobby tires. There are some steep (18% grades) and some long ski hill roads as well as many high resistance gravel trails. I also like to tour with a lot of stuff sometimes so the bike can get heavy. So fellow dreamers, what if there was a hydrogen fuel cell powered bike that only needed one small light battery which could be refilled quickly at any gas station? The result would be a light bike with infinite range. If it cost a dollar to fill up instead of a dime per powerpack I would pay. Make it so!
The company I work for also built one - Linde H2 eBike. It was built mainly as a prototype and was never brought to full production.
You will also notice the range of the Pragma Bike (per fuel charge) is about what a standard eBike range is (60 miles) and it weighs 60 lbs (about the same as most eBikes). Advantage is fueling time if available, but TBH easier to carry a spare battery.
