Something @Cloudgraphy would be more keen about. 
.
@maniashwin3003 true if he achieved something without tapping that footboard Ather should pay him tons of money to learn and implement immidiately.

If we observe closely, we can see the bolts here (Marked in Red out line) on both the sides may be this is how he has managed to fix the center stand.

From your photo looks like honda activaās centre stand, All those claims of we cannot fix a centre stand does now stand void?

I thought Atherās main problem was the physical impact it would have on the battery pack. But if heās found a place where there would be little to almost no impact. Thatās just great. Also weāve to see how it holds up to water now. It would be good if he used some waterproof gaskets or something wherever he used screws.

That stand is not gonna hold up, 3 reasons.
- That point here he has mounted it is a support frame for the battery to rear pillion footrest itās just a support bracket type which connects from front to rear. any alteration in middle will damage or wrap it.
- Even if he has found someplace and realtered the bolt, Now he has to connect both parts of a center stand, mounting it on 2 different bolts, the axis will create unequal equilibrium
- Third, if he has counted both the points and somehow managed it, the case of the battery is now holding the entire weight of the scooter which will create new sets of problem

Itās where the mid frame base (where the motor is mounted) connects to the front sub frame. There is no overlap between that and the battery case. If the load has been distributed properly where the stand assembly meets the bolt, there will be no problems WRT structural integrity.
Of course, this wonāt stop @ather from threats of warranty voidance, because they canāt stomach the fact that others are showing them up.

One of the prime reasons i didnāt like is because of the second point
If I were to make a center stand for Ather I would use the same bolts create a clamp and move to stand to a little bit further to the front (to the actual points where Ather uses it for servicing the scooter) and make the Ather rest to 80deg, not like his which looks like a 88-90 deg straight up, this way the scooter wonāt fall when someone touches.
But Ather can/will stop his warranty if the battery case or the side chassis cracks
Maybe Ather diched the idea of a center stand in favour of looks, that leaning scooter looks which is sporty bike looks, but not versatile for a Indian consumer

If you take the scooter apart, youāll find plenty of things that can be done. Given that the mid frame already functions as a cross member connecting both the LH and RH sides of the frame, hanging stuff off the same mounts isnāt going to mess with balance or load bearing capacity like you fear.
I speak about warranty from experience. I modified my scooter to make it quieter and smoother by adding a vibration damper between both frames, and had to send it back to Ather to get the entire setup realigned at the advice of a friend who works there. Internal politics ensued after the scooter was dropped off there and a 2 day job ended up taking weeks, which also happened to coincide with the lockdown and the scooter was stuck there for months. In the meanwhile, I received dire calls about how my warranty would be voided (even though what I did had no direct impact on the motor or battery), and how Iād have to pay for the work carried out. I told them to do their worst and waited until all the lockdown related dust settled and they finally delivered my scooter after realigning the frames.
Frame alignment is yet another interesting implementation which seems to be needlessly complicated and desined in a way where it cannot be performed without a reference āzero frameā that only @ather has. Had I known that things would be this murky, Iād have saved myself the grief and made reference marks before I took the entire thing apart. Thatās exactly what Iāll do if I decide to fiddle with the frame alignment next time.
With the damping in place and the belts aligned properly, the scooter now glides at any speed without a rumbling floorboard and I find myself doing higher speeds than I used to in the past because Iād back off when the rumbling started building but now doesnāt.
Iām not sure how a warranty situation will now be handled if it arises, but even if it stands void, the end result was well worth the cost.
Back on topic, I donāt care much for a center stand, but what has been done is pretty nifty. Kudos to good old ingenuity. I might borrow the idea to make a discreet mount for a service stand.

Ather already has Service mounts right below the floor board of the battery there will be 4 marking in the corners I have used them with my car jack with wood plank at those places when I went to change tyres

I use a low stool to prop it up loading the same location. This would simply be an easy project to kill some time.

Hmm, And I thought itās just me that the scooter shakes like Hell on over speeds of 60, would love to have some Pics so I can also make adjustments in the future. Did you use the vibration dampening sheets? or adjusted the mounting and added Sorbothane washers?
I have some future projects, will do once the warranty period is over.
- Change the Horn wires from the BMS, I donāt know whoās idea was to put these tiny-winy wires and this horn for this scooter.
- Create or import a Fast charger for 14s cells of at least 40a. for emergency use.
- Change the Transistor or the IC responsible for the Lag in Horn, you can feel it you press the horn and it works there is a slight delay. (or is it just me playing way too much GTA)
- Bigger tires at least 120/70 in the rear and 110/80 in front
- Clear or make the rear tail light Black so it blend in with the black rearguard or to stand out I mean look like Pulsar 220fās tail lights
- Create a perfect X shaped mount for lifting the scooter with a normal Hydraulic jack, or to put it on a jack stands
- Last but not least add and aftermarket ABS and remove the CBS, I have seen and looked at various models and some Chinese versions of sensor disc will fit with Boschās Pulsar 180ās Module, The only thing I need is how I will connect the speed input vs disc input, Thatās for later.
My future projects are all set

Wow this interesting!!! Are there any sources or DIY projects where we can convert the traditional CBS to ABS? I mean the resources which you noted down! Need to figure out the electronics and software where speed is taken into consideration or āto figure out the locking of wheelsā

Speed input is the major factor for the module to figure out whether the wheels are locking up or itās a slow stop, Since Ather used combined wheel+gps+motor Rpm to display the speed on dash board, The only option is to add a wheel rpm speed input sensor, one which is found on Activa 125, create an input gear and spend days in calibration. Here are some sites https://www.aliexpress.com/item/33024286970.html?spm=a2g0o.detail.1000013.3.24623eecptZzoe&gps-id=pcDetailBottomMoreThisSeller&scm=1007.13339.169870.0&scm_id=1007.13339.169870.0&scm-url=1007.13339.169870.0&pvid=b4368531-1714-4130-bc64-9c65230f920f&_t=gps-id:pcDetailBottomMoreThisSeller,scm-url:1007.13339.169870.0,pvid:b4368531-1714-4130-bc64-9c65230f920f,tpp_buckets:668%230%23131923%2330_668%230%23131923%2330_668%23888%233325%233_668%23888%233325%233_668%232846%238116%232002_668%235811%2327169%232_668%236421%2330831%23948_668%232717%237566%23840_668%231000022185%231000066058%230_668%233468%2315617%23822_668%232846%238116%232002_668%235811%2327169%232_668%236421%2330831%23948_668%232717%237566%23840_668%233164%239976%23481_668%233468%2315617%23822&&pdp_ext_f=%7B%22scene%22%3A%223339%22%7D

Iāll do a full write-up on the procedure shortly, post it here and tag you. Didnāt take any pictures the first time around, but I will this time when I take the panels apart to add ram air ducts to cool the motor instead of that ill located fan shaped vibrator.
Long story short, your scooter vibration originates from the motor due to the shaft being side loaded. Since this is rigidly bolted to the mid frame which in turn is rigidly bolted to the rest of the chassis, all these vibrations spread everywhere and the aluminium magnifies this, and thatās what you feel. What was done (rather should have been done during the design phase) is provide physical separation between the mid frame and the rest of the chassis and add elastomer couplers AKA rubber mounts like they do in every other automotive application.
ABS is an interesting project that also crossed my mind, but the cost / benefit of that seems unreasonable at the moment. Not to mention the power required to run that system will be detrimental to the overall range which is already borderline pathetic.

Thats really impressive but looks terrible on otherwise a beautiful looking scooter imo 
peace 
I guess it makes more sense why Ather ditched it in the first place. It doesnāt go well with the overall design.
also need to create an removable battery pack in the boot space Thanks for the idea
2 Likes
I had that idea too. Iām having a 3kW worth of 18650ās and 1.5kW easily fits in the boot, the real issue is of balancing the onboard and external battery and since itās a low voltage system we gotta use some tick wires too to run them together.
The issue is Ather uses proprietary charging protocol and is unknown to us how to get it fast charging or just charging even if we have supported SMPS lying around. I Have read here on forum that vehicles are locked with the chargers they come with .
If you still want to fast charge it, the only option is to directly feed power into BMS inputs.

Making a space efficient battery pack with clean integration into the existing high voltage system and integrating with the electronics is going to be a very prohibitive cost / benefit equation. I had kicked the idea around ever since I bought the 450, but after giving it some serious thought, decided that time and effort was better spent elsewhere.
While people foster ideas, and sometimes actually go ahead with improving glaring deficiencies, @ather happily continues to evade its responsibilities instead choosing to focus on pushing as many sub standard vehicles as possible to as many people as possible to pad their numbers, while issuing veiled and direct threats to the former group of people. Bravo.
