Two to three years ago, articles concerning fuel cell powered ebikes were in the news for a while. Then the whole subject disappeared. Now another manufacturer is making the attempt to stir this pot again. Eurobike was to be the unveiling of the "Vorradle S3 FC" see this: http://www.bikebiz.com...

Unfortunately, in the USA, ebike and a lot of transportation related rights are controlled at the state, not national level. So national organizing for a particular issue is a tough nut to crack. In Arizona, I can ride my ebike anywhere a leg powered bike can go. Not so in some other states.

And the United States of Europe has limited their motors to 250 watts!

I feel like a broken record, but I'll say it again. If you have a steep hill(s) to climb you better get a 48 volt motor/battery system with the battery being 15 amp hours. The motor, 500 watt minimum, preferably 750 watt geared rear hub motor. Hard to find somethin' like that? Yup but otherwise...

I would look into a tricycle.

Battery technology is not there yet for the weight and distance and loads you have. I have a bike trailer and let me tell you the extra weight when it is fully loaded quickly drains the battery down. Test it out before you buy.

We sometimes need that throttle. Legs get tired, chains get broke, and powered coasting is cool.

Swap the throttle out, they are cheap....Sealed off or not, electric components and water are not compatible. If it looks like rain, I take my car. If I am forced to ride in the rain I know that I have already used black silicone sealent on any accessible electric connectors or entrance and exit...

I now have over 700 miles on the bike. I went for the 36v 15 amp hour option since I wanted to be able to get extra distance ( I like longer rides). If you look at the pics of my bike you will notice that the bike is all black with the decals only on the frame and these are black also and not...

Don't worry about a budget. Take out a loan to get what you want and need. It is worth it. Think about how its going to feel not having to fill your ga$ tank as often.

Sorry about disagreeing with you here, but he is going to need a fleet of at least 48 volt, 500 watt perhaps 750 watt motored ebikes with matching 48 volt 15 amp hour batteries. This will get the acceleration to get through intersections without holding up traffic. He will also need several...

I took the plunge (without a test ride) after carefully and repeatedly watching Court ride the Motiv Shadow. He gave it a pretty good review and was my height, so I purchased one and had it delivered to a local shop that assembled it for me. I had to make some modifications. I added a stem riser...

I tried riding an unicycle once in my youth. It was a rigorous balancing act rather than a mode of transportation. My idea is to have the rider sit within the wheel of a motorized unicycle. The top speed then would be limitless, faster than the above videos anyway, perhaps as much as 100+ mph...

150 miles a day at 20 mph, you will need five charged up batteries per day, per bike.

Fantastic!

You paid a lot money for that bike!... So now you are going have 28 extra gears and 3 extra power modes as a technological reserve... Just in case the Zombie Apocalypse is not a collective delusion.

Ravi, here are some examples (starting at 4:10) of wobbling and weaving in this motorcycle video, which collaborates with the mathematical description you provided : I am reminded the oscillating movement of a pendulum.
