At $500 i'll get one.

Sounds awesome.

Up to $1K i think i'm going to get one.


But the question is how to you refuel it ?

interesting

It looks like it's foldable too, or are my eyes deceiving me? It also looks like the pic in the link has a cushion on the rack for an extra passenger.

Environmentally harmful

I used to think electric and now hydrogen bikes were a good idea. Eventually I realised that they use energy that I would not otherwise use by biking and are nowhere near capable of replacing trips that I currently consider necessary to use my car.
So where do they fit in to energy savings? Nowhere.
They just use more energy so people can be lazy while riding their bikes.

I think that depends very much on where you live and what your circumstances are. In some cities which have thousands of noisy dirty two-stroke mopeds then this would be a great idea.

The thought of sitting in a piazza in Rome without having all those mopeds buzzing around like nasty insects is wonderful..

Right, because everyone is exactly like you, therefore this has no value. Far better that lazy people drive 2 or 3 ton belchers than a little zero emission bicycle, right? Must be perfect, otherwise bad!

I wonder....

Instead of just having to use the pedals only for propulstion, could the rotational energy be converted into electricy, that could then electrolyze the water and generate your own fuel?

Or maybe you could just pedal your lazy ass to the nearest refueling station to fuel up.

I definitely think it is a great idea to come up with cleaner '2-stroke' transportation, since those types of vehicles are very very popular around the world, and are also very very dirty (not to mention they have some of the worst emissions per-person mile, worse than the worst SUV)

I agree it would be great if we could replace larger, more energy intensive vehicles with these. I'm just making the point that for a lot of environmentalists (the type of people who would be willing to buy this and the type of people that probably already ride bikes when they can) it might not be as green as it initially seems.
Saying they fit in nowhere was too harsh though, you're right. If we could convince a couple SUV drivers to make a switch to these it would be incredible.
I also don't like the term 'zero emissions' especially when referring to hydrogen, but that's a whole new can of worms.

I will buy one if

IF i can make my own Hydrogen Fuel and be independent from fuel companies.

I want one!

I want one at any cost.

I agree that this is stupid, bikes have this nice concept of being 100% pollution free, except the carbon dioxide you reject by breathing.

What I would do is put a small motor on a bike just like this one and instead of batteries/fuel cell I would put super capacitors, which would help you up on steep climbs and recharge when going down one (also it would help you breaking if too steep). Super capacitors are very effective, vary light (compared to batteries/fuel cell set), don't lose their charge over time, temperature change doesn't affect them and they have high load/unload capacities.

The down side of a capacitor is that it has a smaller energy density than batteries or a fuel cell, but as long as it takes me up the hill I wouldn't care, because I have legs goddammit.

i want to know on which principle this bicycle works, and what should be the cost require for making this bicycle,

Im cool
