I want to go back to a point that, in my opinion, is the real problem of this bike.
For everything else, I am fine with it, but the
power delivery of this motor is very bad and it is driving me crazy.
My main issue is that the motor pushes
too much even at 10% support.
To fix this, I contacted
Specialized Italy customer service. They suggested installing a
smaller front chainring (32 teeth).
After installing it, I found out that it was
not compatible:
in some gear combinations, the
motor shuts down.
After many complaints, it turned out that this was a
known bug.
In the meantime, I had already
spent time and money on this modification.
So I reinstalled the original chainring and
limited the bike to 30% support just to be able to reach
more than 2000 m of elevation gain.
By analyzing the
Specialized app logs (attached file purple line is motor power, pink is my legs
), I noticed that the assistance is
no longer progressive, but basically
on/off.
This happens because I am almost always using the
maximum available motor power, which is around
220 W.
All of this could be solved very easily by Specialized:
- allow a minimum support lower than 10%, for example 5%, or
- even better, after 10%, allow 1% steps instead of fixed jumps.
I honestly do not understand how an app like
BLEvo, created by a single developer and now no longer supported, could be
so much better than the official app made by a large company like Specialized.
