I just was reading an article about fuel cell cars & motorcycles and thought to myself; has anyone put together a hydrogen fuel cell MB? I know it's kind of an unorthodox/impractical fuel source right now but it might be once it's safer, practical and more refined in the future. I think a motorized bike with a hydrogen power source could travel further than any typical $1,000 E bike currently made. Probably more expensive but it would be lighter because it would just need a tank of the hydrogen fuel with an electric motor and of course the fuel cell the and would not need to rely on those E bike heavy batteries.
