No stats about range tell me that the likely range of one canister will be woefully short - I hope I am wrong because this looks, on paper at least, like a great idea.

O.K. I don't know much about hydrogen cell technology, but this looks like it could be a really interesting innovation, especially in terms of range. Unfortunately, as you point out, we'll only know when the undisclosed "detailed specifics such as battery size, weight or range on a single cartridge" are finally published. Too bad they couldn't be more transparent with their data. I was, in fact, hoping to get some further info from the video but, well, that didn't happen. What a poor presentation ! A guy riding a bike around Biarritz (it looks like) and then a few shots of logos and a surfer for some "local color". Hopeless ! Please, somebody help these guys make a video !! Couldn't even hear the bike with that horrible dubbed-in "music". I had to wonder if the machine was actually running on the fuel or just being pedalled along on leg power... hence the "no sound" approach ?!

a price would be nice. just reading and then liking it i can not actually say its a great idea without knowing how expensive the bike is

The problem with all of the hybrids is that the space and weight allocated to the fuel powered device occupies so much space that the vehicle is a poor on battery only vehicle. The space would be better used for more battery. Or, the the alternative, just make it a pure fuel cell bike and get rid of the battery carrying a lot of fuel. At ZEV Electric, we tried all sorts of hybrid combinations. The only thing that works if you insist on a hybrid is a small serial generator with the vehicle really packed with battery. That only works on big trikes or cars. For a bike, for the space shown for the bicycle, you can get 100 miles on battery alone. That is more range than anyone can stand to drive a bicycle in one sitting.

I agree with Darus, above. I ride an electric scooter, and with the new lithium phosphate batteries, what more do you need? There's a whole lot of room if you're willing to forgo cargo space, on these bikes. Rather, I would like to see more development in the brushless motor field, These things DO wear out, and where I live (Canada), you have to use every trick in the book to get any power because of our highly restrictive and biased legislation against electric bikes..

I hope they market the fuel cell assembly as an after-market device, because this would be a boon to the electric wheelchair/mobility scooter user.

Hmmm, all very interesting - but not exactly an informative article, since the makers/developers haven't seen fit to provide any stats...
However, I'd suggest that if they've any concerns along the lines of @Darus Zehrbach's comments, maybe they are (or should be) looking at Lithium-air (http://gizmag.us1.list-manage.com/track/click?u=57c04fd0f2defe64b0f583dc7&id=b28abe19f7&e=2be02f94ac) or, even, Lithium-sulphur/sulfur (http://www.gizmag.com/next-generation-battey-lithium-sulphur/11926/) batteries..? Obviously, these are still in developmental stages and would bump up prices somewhat, but you never know...

Don't we still need petroleum in order to extract the hydrogen for the fuel cells? I hope I'm wrong...

Sounds very good! Was wondering if the Israeli 1000 mile "water car" that uses aluminium billets to store electrical energy could be adapted here?
