I purchased a Stromer ST1 platinum two years ago.
I got a motor replacement a few months back.
My stromer new motor is Power 48
TDCM S20 . I am trying to change the speed of boost mode using the code 3775, but after saving the settings it’s coming back to 00 and the boost mode speed does not go above 20 km/h.
Can anyone suggest what should I do.

Is your ST1 a 25km/u model originally? In that case, codes to change the top speed higher than 25km/u cannot be saved in the computer.

Thank you so much for replying.
With the full confidence I can tell you that in the previous motor which came with the bike pre-fitted, I was able to change the boost mode speed up to 40 km/h. And whenever I activate the boost mode it was able to achieve a speed of 37.7 km/h.
I tried to even set the speed between 20 to 25 km/h but it’s not changing.
It’s keep on coming back to the factory default of 20 km/h.
And whenever I enter the code 3775 or 3773 it’s showing the values as 00 in both of them.

Oh right I missed that: you live in Canada?

In Europe the legal maximum speed for a regular e-bike is 25km/u, in Canada it's 20mph (which is about 33km/u). Above this, the maximum is 45km/u for a speed pedelec.

You have put a 45km/u speed pedelec motor in a 25km/u (Europe) or 33km/u (USA/Canada) Stromer? Most probably the sofware can't communicate with this motor. Maybe also for legal reasons, because if you want to go 45km/u, you need a licence plate, insurance etc. etc.

I don't know how to fix this in a legal way (nor illegally for that matter). If you want to use this motor, but limit the speed to 20mph for example. You probably need to have the software changed. Only a certified Stromer dealer can do this. Maybe it will work, but I am not sure if you can still limit speed to keep your Stromer legal at 20mph.

Hi!
Thank you so much for replying and letting me know all the details which I was not aware of.
If you don’t mind I would like to know one more thing, whenever I used to press power and minus button my display back light used to be turn on or off but now when I press this something called “SENSO 70” Appears and I can change it value from 10 to 90 with the difference of five.Can you tell me what it is. Thank you in advance.

Sounds like the sensibility of the torque sensor. The higher you put this value, the stronger your motor will respond when you put weight/force on your pedals. A higher value will not change the top speed, but it will give you more support.

However: the term SENSO 70 does not ring a bell for me in the Stromer context (Stromer uses TMM sensor). Just play around with the values and see what happens, if you can feel any difference in support.

A newer software version prevents setting the boost to a higher speed.
This software came with the new motor
I had exactly the same issue with a new ST1 motor and this was the answer of a well known dealer in Amsterdam.

Did anyone managed to record any value on the 3773? I’m aiming at temporary downgrade my ST1 (model 2017) to max 25km/hr. But whatever value I set it always go back to zero. Does anyone knows of another code to limit the speed?
Thanks!!

Code 3773 toggles the speed between legal EU e-bike speed and legal USA e-bike speed. So it switches between 25km/u and 33km/u.

As far as I know, there is no code to downgrade a 45km/u speed pedelec to a 25km/u pedelec. (Legally, this is also not an option.)
