Can't get my ES2 go faster than ~25Km/h. Need help please.

Hi folks! It's my 1st post here.

My friend's wife has fallen off her ES2 and chipped a tooth. Now she's scared and she doesn't want to ride it anymore. The good news is... I got a free e-scooter!
In fact I'm enjoying riding it so much I'm changing some of my personal routines to use it to go to town for small shopping, meeting friends, or just go out for "a one battery-long fun ride".

I've been reading stuff online and fiddling around with CFW built on the website.
I've been able to give it more power so it goes up hills much better, and go from the original 20Km/h to around 25. Also I find the FreeWheel setting (KHERS/12) very useful as I can use gravity downhill to save battery (I think in some slight slopes it gives more range than regenerative breaking).

But I cannot make it go any faster than 25Km/h!
According to the settings I input on the CFW builder, it should go faster. But it doesn't.
Also, I've changed its region from U (limited to ~20Km/h) to S (limited to ~30Km/h) but in practice I see no change in top speed.
Info on Android apps show settings that the e-scooter is limited to ~30Km/h but it never goes beyond ~25, even with a 100% charged battery. (I only have the original battery, no 2nd one installed)
I've also noticed that when applying CFWs built on the site, the e-scooter ignores all modes (eco, white and red S) and just behaves the same in all modes. In practice, I've lost the 3 modes and it looks like it is always on the red S mode. Is this normal?

Even if I install the latest official firmware and with the region set to limit it to ~30Km/h, in fact it doesn't go faster than 20! (not even in the red S mode)

AFAIK this e-scooter was never sent for repairs, meaning it still has all original hardware, battery, controller, etc.
The e-scooter is 4 years old but the battery is still in good condition, so i think I can exclude the battery not being able to supply enough juice for it to go faster. When it was given to me, it had done around 300Km.

I've tried lots of possible configurations on the CFW builder (even tried the old version) giving it settings to go faster than 25Km/h but it has never worked. It seems that all top speed settings are ignored. I think I've done all options I could have done (at least that I am aware of) and ran out of options on how to solve this.


So, wiser ones, can you please help me out?
If you need more details or info, just ask.
Thank you very much for any help guys!!

It sounds like you've already done a lot of tweaking with your ES2. Have you checked the tire pressure and the condition of the wheels? Sometimes, a lower tire pressure or worn-out wheels can limit the speed.

It's possible that the motor or controller may have limitations that prevent the scooter from going faster, regardless of firmware modifications. Replacing these components might be necessary for a significant speed increase. tiki taka toe

Regardless of whether or not the software is modified, it is possible that the motor or controller has constraints that prevent the scooter from traveling at a quicker speed. In order to achieve a remarkable acceleration, it is possible that certain components will need to be replaced. geometry dash
