Electric Motorcycles & Electric Bicycles

Technical revolutions when? Surely we are more interested in the direction of the industry moving forward?

For instance

Battery Tech was under a lot of development 5 years ago but now there is barely an announcement every 6 months

Swapable battery packs have been around sine we had rechargable batteries in the 80's

Wheel hub motors, are they actually any advantage at all? Electric motorcycles and cars are doing everything they can to keep motors out of the wheels because of the poor performance of unsprung weight so are their new lightweight motors that favor hub motors over central drive motors?

So on and on.

The technology listed here may have been important in the development of the current e-bike population and fleet delivered to customers but in my view, many of these are an example of what we want to get over in order to take E-bikes to the next level and revolutionise where they are headed..

Okay ; so in your opinion what is the next best thing that is emerging in the E-Bike industry that is so compelling that everyone should stand up and take notice ?

Yes, I have mentioned the evolutionary progress over the last decade, but its because of small steps not large advances that we are where we are today.

There is nothing revolutionary yet to come forward with batteries and/or motors, but there is revolutionary technologies quietly emerging in the power conversion industry that is leading to conversion rates up to 99% efficiency !! Yes, that is revolutionary, but there are few (if any) on this site who know why (IMHO).

So i presented my thoughts on what has happened - now YOU tell us what is about to happen.

Thanks !

I never claimed to know I I just pointed out the obvious error. But since you ask I'll give it a go.

1/ Change in battery make up from Lithium Ion to any number of new materials that will make for a bigger supply or batteries with equal or better shelf life than Lithium Ion because we dont have enough Lithium ion on the planet to even turn every wheeled vehicle from Gas to Batteries we need to have batteries made of a different source, I think Aluminium will be the source carrier material and they can be recycled so easily.

2/ Variable magnetic field electric motors. The machine is characterized by its structure that uses a three-dimensional magnetic flux to increase the torque density and adds a variable-field function to decrease the electromagnetic loss.

3/ Independent home electricity generation. Mains power is expensive and centralised supply is already a problem in supply before adding cars and bikes to the grid and getting hideously expensive. Effective charging of personal vehicles will only be able to be achieved when proper independant home electricity generation systems are rolled out as ublic charging is already a mess.

4/ Are batteries or Hydrogen ICE vehicles a better future? And for what vehicles?

Thanks for the opportunity.

Comments to your response :

1/ agreed !! - this is the holy grail of the planet to get beyond a (low cost) magnitude of storage capacity for small cells such a person could charge their cell phone or laptop for a week, and cars would need 1/10 the amount of batteries -or- they could travel longer without a charge if there were more 10x batteries.

2/ variable magnetic , variable reluctance, axial flux vs radial flux, permanent magnet types using rare earth minerals are all here. The question of *how much* better they can get (torque vs energy) is the magic key here and just like ICE engines took decades to improve, i think that it will likely take a couple of decades to get there. Also emerging materials and meta-materials may help here.

3/ I *whole-heatedly* agree !!! HOWEVER this is in direct opposition of what the utility companies want and what the governments want since the corporations make profits and the governments tax the usage. Energy Independence is AWESOME for the individual, but the forces-that-be DO NOT want this and will do everything to stop or delay this. - - - I watched the solar industry destroyed by regulation, taxation, import control, permit fees, bloated installation costs, and so many other sellers, resellers, and installers rip off people. The only way this will ever happen is for a very savvy technical homeowner do it themselves and avoid intervention (if possible).

4/ Personally i see the Hydrogen / Solar / Electric Storage mix as the best winning combination for heating/electric generation for a homeowner -WITHOUT utility companies involved. But that is a dream vision that i am sure few will ever achieve.
