Given all the resources and expense, it would take to diagnose, analyze, re-engineer hardware, re-engineer software, test hundreds of new versions to find the one or two that are failing, and to establish who pays for this and replacements, whether trek or TQ, or how to apportion, all to satisfy...

That is exactly the sound mine made before talked to LBS into swapping motors with another bike on the floor. I can reproduce the sound faintly in the new motor, but only if I'm trying to operate it low torque from me guess the odds are good if you can swap motors again, that it you might get...

I really look forward to your hearing what’s going on with PQ. Several months ago my local bike shop swapped motors and my motors been perfect ever cents. If I try really hard I can make it reproduce the sound, but almost never does it occur on its own

This seems eminently reasonable. I was one of the first ones to complain about the grinding sound on this forum but since my local dealer swap the motors with another bike my EXE has been perfect, a few months ago.

“Sounds like the predator “…. awesome description. Almost makes me wish I had it.😊

It may be a problem that takes a lot of resources to define, analyze, and solve. They may have taken a look at it, and determined that it’s not worthwhile fixing it, comparing the resources to fix it to the minimal benefit to only a few riders and the minimal loss of PR? May be like the old...

My second, swapped, motor only occasionally makes the sound, so I'm worried that if they have a software change to try to correct for the noise they may have made a trade-off or a compromise for something else that may affect performance or naturalness of engagement. At the moment I'm thinking...

I have followed the lithium battery issue very closely over the many years that they have been out and what Montana St Alum says is true. Basically you can think of lithium batteries as not liking to be cycled, and certainly not to the limits. A typical computer battery or cell phone battery...

The frequency of the clatter sound is similar to mine.

I have both, and I think the EXE is a little more powerful. it is not as much more powerful as I anticipated given that the SL is 30 Newton meters and the EXe is 50 Newton meters. The fact that the EXC is more natural may hide some of its improved torque.

I have also experienced some funky behavior in the high mode, only in the high mode. Sometimes variable support, sometimes more rapid cut off when slowing pedal effort. I assumed it was a software thing, where the program can’t always handle perfectly well all possible scenarios of all...

I experienced it a lot on the first motor, but it’s strictly a sound thing no functional implications at all, just very annoying in that my expectations were so high and it was not present at all in the first 30 miles, 50 km. My local bike shop eventually swapped motors, and it is barely...

LBS swapped my noisy motor off with another bike with a brand new motor. It was wonderfully silent for 35 miles now the same grind clatter starting again. Still a wonderful bike. Maybe this new purported firmware algorithm will help. And I would guess that most people would not notice it.

That reply has been sitting on my screen unsent for a day and half, before Robs answer from TQ, I have now ridden two new , unsold , EXEs and could only reproduce only the slighest question of a pissible grind in one On the other, where conds. were better to test, I could get no grind, just...

Excellent points. My grind noise is not associated with any performance issues at all. Perfect performance from the motor and the transmission. I also have heard a rare isolated ticking noise. May be only two or three ticks at a time, And could not decide whether it was from the motor or the...

. At 9:15 inches. “ freewheel clutches”.

Just heard from my local bike shop which has been in touch with both TQ and with Trek and they say that neither is being very helpful to them in terms of a warranty claim on my motor . ( This is related to the grind noise). Trek or TQ says the only thing that can be done is to make sure the...
