Duotts c29 badly programmed PAS controller

E-bike model is Duotts C29, 750w.
Problem with this e-bike is that on every PAS levels 1-5 it just gives out MAX Power/ Watts , and only limits max speed... and manual throttle is also max speed limited by the currently selected PAS level on the display, and there is no setting available on that display that solves my issue....
From google i figured my generic display model is called ''G 51'' , serial number on the back: XN22512307215168. Sciwil looks to be OEM manufacturer for it, and in their user manual it says: ''explanation to the above Serial Code: 1：Program can be overridden（0 means can not be overridden)''. So that gives me hope.
www.sciwil.com...
And numbers on my actual controller are: JH4AJ6021DZYK , Dongguan jing hui Controller (duotts says its 48V 21A sine wave)
I went to test it out, just to be SEVERLY DISSAPOINTED by how BADLY this bike is set up /programmed.... No matter the PAS level selected it just gives out max power, and only limits its max speed... that's so dumb and non-usable... and on lvl 1 its limited to 19km/h! Right now its an electric scooter, not a bicycle! And to make things even worse, Throttle is also limited in max speed by the level of assist i selected!
Here is the example of how it should look like / what I want to achieve:
PAS 1 : 80W / 10KMH limit (OR NO LIMIT, NOT THAT IMPORTANT)
PAS 2: 150W / 15KMH
PAS 3: 350W / 30KMH
PAS 4: 500W / ...
PAS 5: 750W /...
Throttle max speed unlimited or not affected by the selected level of assist : give out W depending on how much throttle i give, independent of PAS settings
Anyway, you get what i'm saying and why this is so bad as it is right now.... i need for pedaling to make sense and extend the range per my desires (hence the levels), And my throttle needs to be usable as it is intended, for me to have all the speed and power with a twist of the wrist! Oh! And i tried in settings P05 selecting 3 levels mode (instead of 5) and to my surprise its even worse! Those aren't programmed at all! On lvl 1 it gives max power and no speed limit, it just goes ! Also playing with P12 ''power boost start strength'' does nothing, did not noticed the difference, but that doesn't matter anyways, it is smooth enough, problem is that it does 750w all the time and i can't limit it!
How do i go about it? Can someone point me to the usb cable and PC software to use so i can play with it? Where do i plug it in? I hope that's possible...
Or do i need to buy new LCD that would have advanced settings i need, and would work with my controller? Or a whole new controller with display that would work with my motor? How do i identify what motor i have and does it even matter? What fits / what is compatible with what... anyway, i'm new to this...
Bike itself looks alright for the money, and has plenty of power really... but programming for it... the laziest thing ever, Its really astonishing that they send out bikes set up this badly... This one thing makes the whole bike unusable and dumb, ruins the whole product that would otherwise be good....

Go to P10 and switch it to 001. It disables the pedal assist. Leaves only throttle enabled. Works perfectly.

[@tgaborhome]

What you are looking for is a bike with a torque sensor, not a PAS control. I can't say anything bad about this bike either. I am over 4000 km. I had to learn to use it. I have used a few rented ebikes, of course they are only 250-300 W, it cannot be compared, this C29 is so much better! It's like you complaining about a sports car that it's too powerful.

[@vitserp]

On mine I disabled pedal assistant altogether, now I only have throttle control. Which makes bike safe althouth this makes bike more like electric moped that bike. But this is typical with chinese electric bikes. You get what you pay. For me it’s acceptible as I saved thousands of euros for more advance bicycle.

[@KestasL007]

how desable???

[@vitserp]

Hold + and - on the controller. Go to menu and change pedal assistant setting acording the manual.

[@michakoodziej8760]

Set P10 to 1 instead of 2. It works great 👍 Now, finally, you can cruise at 5 km/h without hurting yourself.

[@stavman8536]

.....2100 km with out any problem at all !!! Have manage to ride 160 km in one day with a second battery !!!

[@diarmaidok]

Is it possible to plug in a different lcd controller and reprogramme the pedal assist limits to 5km/h pas1

[@omrfuxksony406]

How do i get it in blutooth mode??

[@kimboidi]

Same thing with my GUNAI GN27. Cant get feeling to pedals it just pushes.

[@Huck99992]

Not only me, i just i sent him back this bike its dangerous

[@adax7189]

somehow if you put top speed exactly at 67km/h it removes limit

[@noahsolis2533]

Thanks a lot for your comment, I've been looking all over on how to quit the speed limit and this is the only thing that helped me ❤

Sterownik jest zaprogramowany tak, aby nie akceptował poleceń z wyświetlacza LCD

[@zokirataj4046]

Maybe is max speed 100km/h and this is not default! Why you not set to 250km/h?😅

[@stavman8536]

there is something wrong with your bike...... mine with 1st has max under 10km per hour and with 2nd max 16....3rd max 26 .... so i have manage to travel 80 km distance before batterie goes too low !

[@skyliner4610]

Its not about max speed, its about power. I can limit speed with P08 setting, it translates to PAS levels, if i limit whole bike to lets say 40, lvl 1 will be 10kmh. Problem is that it always delivers max Power/Wattage/acceleration. On lvl 1 for example, it should provide only 20% of power, not the whole 750w. This bycile is dangerous, i fell 2 times because of it, i turned off PAS completely and only use throttle now, because you cannot control acceleration otherwise

[@skyliner4610]

Also, no way you got that range. I did testing, 42km on a circut on 35kmh cruise control without stopping. And than in city limited to 30kmh with pedaling and lots of stops i did 52km range.

[@stavman8536]

@@skyliner4610 i haven't touch menu at all cause everything was perfect setup ☺️ have ride 1200km until now and i only have positive words to say about this bike. Have also replace freewheel with 11/28 so i can feel the pedals at +40km per hour.

[@stavman8536]

@@skyliner4610 ,...80 km in 3,5 hours, average speed 22kmh an max downhill speed at 63kmh ....and return with some juice left probably could ride +10km more... I also order second battery so i can ride nearly 180 km distance with only pedal assistant and low speed 16 km per hour at uphill ofcource.

Thats why O bought a bike for 672 euro

THAT IS VERY BAD INDEED AND SCARY MAN CAN CAUSE ALOT ACCIDENT NOT ON PURPOSE ITS LIKE PULLING ITSELF TO 18 + AUTOMATIC SHOULD CALL COMPANY TEEL THEM THIS DUOTTS IS PRETTY GOOD COMPANY EITHER WAY DO GOOD BIKES

[@MortalKastorR]

And so...did you found a way to overcome this shitty engineering?

[@MortalKastorR]

Ok, so now these bastards are selling a controller with a speed limiter (probably the previous model) on their site.

[@ash-yr5xt]

What that mean? Anybody buy it now won't has the same issue? People saying it's because they use torque sensor that why ​@@MortalKastorR

bay new controller Change this problem

[@Huck99992]

Jaki kupiłeś? Jak dokładnie to rozwiązałeś?

[@pablox11NEW]

@@Huck99992 sabvoton programowalny rozwiązuje ten problem tylko większość sabvotonów jest bez systemu pas co tworzy następny problem . Podobno najlepsze rozwiązanie to korba z czujnikiem nacisku mierzy z jaką siłą naciskamy na pedały i o tyle wspomaga.

[@miguelea728]

That happens with all the ebikes. The problem is yours. You need to learn when to stop pedaling and how to play with the brakes in order to control the acceleration and bike speed at every moment...

i see u have problem not a bike :D
