Love the old barter system where no money changes hands, the good old days!142 kilometres again David! You are an improbable person!
He rides my e-bikes, doesn't he?![]()
David puts us all to shame, he is a well oiled machine!

The one that seems to be falling into the sea.
I only can hope you would buy yourself a decent e-bike one day, and I wish you that from my heartwobbly beast
It was windy over here too. Look's like your headed out on a multi day journey. What's the destination?The wind, OMG, the wind...

What is the elevation gain equivalent of fifty miles of riding into a forty mph headwind? It has to be a lot.
The scenery was spectacular which kind of made up for it:

So after my exciting ride above I discovered I broke x2 rear spokes. I will write about my recent suffering of fools once the dust settles and I am back up and running, next week. I was able to take one of my mistakes work and made a ride. Unfortunately I broke x2 more old spokes so sent the rear hub/wheel out for a total rebuild.....Wow @Stefan Mikes - almost looks like pre-COVID photos there; SO NICE TO SEE!
Sorry for no photos today. Canadian geese and Mallard ducks in muc ponds was not photogenic....
But I have exciting news to report. My 1999 EVG did more consecutive miles than she ever has done before. I just did 26miles (42km) and returned with 59% battery (62% post rest). I am really excited as I still have a battery pack coming; so I may just hit my first Century Ride ever!!!

I think what Mission Control actually shows is the power drawn from the battery (there is no way to actually determine the motor power while it is very easy to measure the current and voltage to multiply them and get the power figure). Since we know the 1.1 motor produces 240 W max and the reported value was 300, it indicates the motor efficiency of 80% and it sounds about right.watched mission control with “motor power” pegged to 300w for almost the entire climb. For some reason (cadence/gearing?) it was MUCH easier for me to put out 150w when the bike was adding 300w than it was when the bike was putting out 50.
Interesting - the field is sort of mislabeled then, since “rider power” is clearly a torque x speed measurement and not an internal body measurement but usefully so as it allows you to calculate range and so on. 80% would be a reasonable value for a brushless permanent magnet electric motor, i think.I think what Mission Control actually shows is the power drawn from the battery (there is no way to actually determine the motor power while it is very easy to measure the current and voltage to multiply them and get the power figure).

I agree with the phenomenon (that you describe) of inputting more leg power at high motor assistance than it happens with low support. I cannot explain that at all but I get very similar relationship when I ride my Vado 5.0 and measure the leg power against motor assistance with the BLEvo app. Let us say I need to ride together with slow traditional cyclists. I set the assistance down to say 25%, and after the daily trip I realize my leg power was just puny. Now, the more assistance I use the higher my average leg power turns to be. Finally, if I set the assistance to 100% and do a (say) 8 km/5 mi sprint, my power input becomes quite high as for my ill legs.
I don't know why that happens. It might be we just try harder ourselves with high assistance on?
Not necessarily. There have been many charts for many mid-motors published, and the top efficiency was reported at about 80% max. For instance, the Specialized 1.2s motor I'm using appears to work at 78% top efficiency: the rated Max Motor Power is 520 W, the power drawn from the battery with the motor at the top power is 666 W, hence 78% efficiency.Interesting - the field is clearly mislabeled then, but usefully so as it allows you to calculate range and so on. 80% would be a reasonable value for a brushless permanent magnet electric motor, i think.
