Do our Vargs actually, "regen"?

I rode the other day for a quick hour long ride on a route I have taken many times (aggressive trail riding). At the very start I decided to set my "regen" to zero instead of my normal 50%. What I found was that I had much more control over the deceleration (and transition to acceleration) of the bike AND that I felt my battery drain was weirdly less than usual. Shouldn't "regenerative braking" put more charge into the battery? Do our bikes actually have, "regenerative" braking? Or is it just programmed drag on the drivetrain?

I'm not sure about the repowering the battery bit (i doubt much if any)
Letting the bike roll will save power too like riding more smoothly
I run 25 % regain for the transition / more upsets the bike while braking cornering
I have been having trouble with jumps and whoops so might do some testing with it turned right down
see if that helps(sudden hard impacts feels like there is some cogging going on)
On the engineering side I can see this would happen with electric motors.
Hoping to get some testing in before easter. The weathers not co operating though.

It does recharge. But with you slowing down more due to engine braking you also need to do more accelerating, wich actually concumes more power.

Deviating from the topic, sorry. But I just had an epiphany...

You are absolutely right! I used to run 50% regen and I thought it was really good at Glen Helen when the track was wet and tacky. Then I switched to 40% and I thought it was better. Yesterday, at my local dry/hardpack/gravel track, I caught myself struggling to do two-wheel slides into a small berm consistently. I just realized that I was having a difficulty balancing between a slight braking and a slight acceleration while cornering. Stark has improved the partial-throttle acceleration recently, thank you very much for this. Perhaps I could decrease the regen now to bring the deceleration closer to coasting to make the throttle off/on transitions smoother, more seamless.

I can always add more decel with a LHRB. But reducing the decel by adding throttle is just not smooth enough.

What electric bikes are missing is the "disengage the engine braking with the clutch" option. Unless you set the regen to zero and add the engine braking with the LHRB when needed.

I am going to experiment with reducing my regen setting. Too bad my local AZ track is going to close for the summer soon.

Have you tested and confirmed this? I played with mine on a long downhill, and never saw a rise in battery percentage. Okay, what I did wasn't a very scientific test, but if you have more hardcore data, please share.

My test is about as good as yours, but i saw a rise in percentage.

Was it at least 2%? If it's rising by 1% it could just be oscillating (for instance display says 30%, then 29% and back to 30% when in fact it's oscillating around 29.5%).
Can't really think of a more practical test than long downhill but not sure how much you could supposedly regen.
