I get the impression that despite his age he could give most cyclists a run for their money even on a normal bike so he is only using the electrics on the really tough bits.
All credit to the gentleman for his development work but anyone over in the UK can purchase something along the same principles from that firm down in Winchester. Ok, their bikes are double the weight of the one seen in the link but the small battery, used sparingly, can allow some fairly lengthy trips.
I wonder how many ebikers have never considered/never heard of the Cytronex system and bought one of those 30kg clunkers then used (had to use!) power all the time when they ride. If I were in England, I'd certainly consider that type of bike as they have power when needed but are light enough to ride easily over most terrain. I think those bottle batteries are good for up to maybe 20 miles but in all honesty, how many ebikers actually ride that far in one go?

the guy is an athlete, he runs marathons, he sure can ride 120 miles in a day without assistance.
BTW, what is in his battery? must be a Sulfur one to pack 800WH into that space.
As I have said many times on this forum, I am a big fan of carrying only the battery size/weight that you need for a trip. My daily use (10 mile round trip commute) DIY battery weighs 1kg, 36V, 3.0AH and will give me around 15 miles albeit in flat Cambridge. I also have a DIY 2kg, 6AH battery. This is my lightest electric folding bike a Brompton M2L-X at 11.5kg excluding bag/battery.
Even if you had a longer commute of say 10 miles each way you could keep a charger at work.
The trick is to get the battery sizing right and to make sure you dont take it down below 1/3 charge to ensure it lasts you a few years. The beauty of the DIY battery route (not for all I know) is if a cell goes its easy and cheap to replace. I still have my original DIY battery which was used daily for over three years and has 6000 miles on it. Changed two cells in that time.
Of course using Lithium Polymer batteries is another alternative, but not advisable unless you are very confident in their safe use.

I should add that unlike a folding bike that is build to be carried that I don't really understand, within reason, say around 15-20kg the need to get a touring/mountain bike weight down given that you don't need to carry it and once you put luggage on it the weight shoots up anyway ?

That's a re-badged Annad with Keyde motor. You can probably get one direct from Annad if you want one. They do a range of light bikes including MTBs. I tried one, and it felt quite torquy for such a small motor.

Climbing, acceleration, ground handling ie. through gates designed to stop motor bikes.
Also off road I find it easier to control/throw/jump a light bike.
But the above only applies if you are fit and like extracting maximum performance from your bike, now days an over weight cruiser does the job
