First: excuse for my poor english writing
@Mitchell, I am very sure that I have the same problem with my ST2.
I am glad that you defined this problem very well.
Quote from you:
It feels like the assist mode is cutting in and out. For example I will feel the assist for about 4 seconds, then its like assist has been turned down (not completely off) and the peddles have resistance. The peddles require more pressure. After applying that pressure for about 2 to 3 seconds the assist comes back on and there is no longer resistance.
Next point play by me along:
I cycle 80% of the time in mode #2
1) This problem seems to occur more in hotter weather.
2) During a trip - no problem to encounter.
But then, when I stopped at a red light for a few minutes and keep the front and rear brakes pressure hold, sometimes I have/had a little later resistance problems (as described above).
3)Mostly I solve the problem with the next things:
*A little mechanical and electrical 'switch' on the 'gearshift'
*Plus squeezing and wringing at the brake lever and the little cylinder in the brake handle / sensor
*a several times momentarily braking
*pushing a little harder on the peddles
And mostly the problem is solved - This is not funny, but I 'm able to continue cycling.
Currently, as I just indicated braking with rear brake, and I have less problems.
I know someone on an other forum who indicates the same problem.
He told me that his brake sensor was totally wrong mounted from the factory.
I do not know how this is completely resolved, but apparently I never hear of this. - I'm going to ask
Indeed, in my view the batch of the bike, rather than a design fault
The first days after the occurrence of this problem I felt myself deceived, like "7000$ " for a bike - and then something like this...
I'm sure this will be solved, maybe not now, but as several people have this common issue...
I guess Stromer has to take action and solve this.
But: Without this problem, my ST2 is a dream bike
And now the big question - how to locate this problem and how to solve?
I hope we can solve this out - and read more on this thread
ps: I also wonder if their is nothing about the torque sensor/ or recup logic/electronic ?? big questions
Regards
