Does using coasting regen improve the efficiency? I’m confused if I should have it turned on or just turn it off. I have it turned on now but I don’t like the way I get pulled slightly every time I don’t accelerate the bike. I think it would be better if there was a manual way to activate the regen

Hi Chanakya.
The coasting regen function can improve efficiency as well as not improve as it depends on the driving scenario.
Scenario 1:
Mid to high traffic, small roads.
In the above scenario, there is acceleration and braking at regular intervals. So using coasting regen works best as now instead of using brakes to slow down you use regen. It works smoothly and with a good relaxed ride, you get increased range as well as less wear of brake pads.
Scenario 2:
Low traffic on wide open roads.
Now if you are cruising on an open big smooth road with minimal traffic, then using coasting regen will not be beneficial and in fact, cause reduced efficiency as when you release the accelerator instead of smoothly coasting ahead with the momentum, the vehicle will begin to slow down too early even though the road is open with little traffic and to compensate the speed you again accelerate. So in short you are using more energy to cover the same distance.
The best way is to turn on and off the coasting regen based on riding conditions to get the best efficiency.
I own a 2023 Ather 450S which has a 2.9 KWh battery capacity & by using the above points I get 35 km/Unit efficiency for pretty much each ride all in Sports Mode & get an 80-85 km range for every full charge. It is great as on full charge the dashboard shows only a 70 km range in Sports mode.

The manual way to activate coasting regen is slightly pull the brake lever, make sure the Coasting regen is off. This will engage regen without the brakes engaging so that you have control when you need to regen or when you need smoothly coast without any braking.

Hi, I just enabled coasting regen in my 450x
I tried multiple speed modes and i feel the RPM is definately reduced to 50% atleast .
Earlier , the wheels used to move much smoother when not accelerated in same road. Even in the downhill road, the wheels are no smooth with this feature.
Anyone else observed this ?? If we are reducing the RPM, then what is the use of this feature ? This will make u accelerate more as the vehicle slows down and in turn its same range without the feature

Well ! That’s what ‘Coasting Regen’ means… Whenever you release accelerator, regen kicks in and charges the battery. Earlier it used to be on only when the accelerator is twisted back. Now when the ‘Coasting Regen’ feature is turned on, it kicks in irrespective of twist.
Should you ‘not’ liking the feature, you may please turn off in the setting.
Some may definitely like this, as braking is not needed.
Well, I too turned off

Did anyone notice range drop in 450X gen 3, after the atherstack 6 update? My scooter is behaving very random after the update. I am a balanced rider, and before i used to drive in smart eco and used to get more than 1km/1% charge . After the update it went really bad. Now from 100-80% i am still getting 1km/1%, but right after it goes below 80%, then i get 800meter or so per 1% charge. My riding habit hasn’t changed. And this just tbrows off my whole distance i can travel. And this happened suddenly. I never noticed a gradual decrease in range. My scooter is 2½ years old has ran 17000 km.
Does anyone know about any such issue?

Same here buddy. I travelled like 33kms today and the SoC went down by 67%. Started with 72% and ended home with just 5%. Thought of starting a seperate topic for this but, saw many people are reporting this issue! Many people said it might be due to the degradation of the battery but I can experience this drop (say 1% per 550-700m) in all SoC’s even though I’m in 80,70,60%…the drop feels the same. And also the cooling fan enables simply for no reason. Like whenever I go above 35-40kmph+ I can see the fans turning on. Earlier it used to activate above 50kmph. Ather must look into this

But if it was battery degradation, then we would have seen a gradual decline in range, right? Everything was working fine and this issue just started out of the blue. Did you also get this issue suddenly?

Yeahh. I just completed my 15k service a week ago and before it I kept my tyre pressure about 27psi in the rear for a week before the service. From that time I have been experiencing this issue, but I thought this was mainly due to the low tyre pressure but after servicing the vehicle I noticed that the issue was not due to low tyre pressure and was concerned coz of something at the Ather/Development side. And also if the battery has degraded you can’t experience an overall range drop. Coz only the cells of a particular range could’ve got damaged say; after 30% you can experience an abnormal decrease in SoC since the cells could have got weak. If the range drops overall then it could be considered either a software issue or maybe a weak battery pack. But 2 years old with just 15k kms driven overall, I won’t say the battery pack has got weak since I believe Ather has not gone to that low quality. Should be a software issue.

I hope it’s a software issue. If there was an option to insta atherstack 5 and test the range, that would have been good. But sadly, that’s not an option. Anyway, I plan to raise this issue on my next service. If maybe Ather fix this through an update before that, then I guess everyone will be happy.

Try turning off coasting regen then test, rider of Ather has said they are getting less range or efficiency in coasting regen for long ride

For short ride coasting regen is good

It’s already turned off. I haven’t been using coasting regen.

Checkbyour battery health mine seems ok, but you can wait as they will roll out stable version in few days with ping my scooter and forced regen fix(probably)

Same here. The battery drain after Stack 6 is horrible. I got a range of only 57km from 100% to 17% and I drive economically without any harsh accelaration. The range took a nose dive. I am forced to charge frequently since I am not sure how much range I might get. So much for claims during the community day event that Dashboard reliability has gone up to 90% something.

Yes. When you drive, do you get a high range from 100% to 80%, then once the charge goes below 80, the range becomes worse? Because my scooter does that. Just wanted to know if that pattern is there for others. Or does the discharge is consistent from 100 to 0%?

I am getting worse range from 100-90 then the range seems to be good from 90-80. And once I go below 75 the range is on a constant endeavour to commit suicide. And it falls of a cliff.

Yes driving on one mode will fetch a better range. But accordingly situation also matters, what I have observed is in Ride mode I get approximately 90kms range as well in sports mode it’s 75-80kms in city limits.

I think for people who drive only in Sport mode , before we used to go below 60 , we used to get more range (100).
But that pickup has now reduced to 55 or 52 , We get used to speed of 60 , I predict thats why we are getting less range.
As per many people are also complaining abt the warp is not warp anymore , I believe that any mode is not that mode anymore…
Specific mode pickup has reduced after the AS6 update.
Orelse is my prediction is wrong , how can we prove that our range has decreased due to AS6, as we are facing since AS6 Update.
