I had tried some of the same ideas, like holding different parts to see if the sound changes. I tried stuffing foam into the top tube through the display opening, but, alarmingly, it made the motor control buttons erratic or downright unresponsive, but worked again with the foam removed...

Perfect reason.

Thanks Antonio, good to hear from you. I remember being surprised at your very modest assistance settings back then (to the point of asking why an e-bike). Glad to see you are holding steady. The noise makes itself heard on average roads on what would otherwise be a quiet part of the ride...

Thanks. I also suspected the top tube and had shoved some foam into it, but it didn't help. I may try to do a better job, but don't want to mess up. I've been looking at the manual. Can you tell me: a) Can the Smart Box be pulled to the display opening to check its foam pads. b) What the...

On topic: TQ Motor Settings Many here have been riding TQ HPR50motors for good while, long enough to know what motor settings work best for them on the road. What settings have you settled on? Mine are broadly rounded: Eco 100W, 100%, Rapid... Mid 200W ,200%, Gradual... High 300W, 200%...

Ratttle Rattling noise from inside my TrekDomane+ SLR6 frame, on even slightly rough pavement, is spoiling my rides. Possible causes include 1) loose internal wire connectors banging against the frame, 2) loose nut or other bit of hardware bouncing around somewhere, or 3) ?. Looking for...

Just received a TQ notification that an HPR50 firmware update is available. In typical TQ style, it is a terse note with only hints as to what is being improved. Looking for Trek, established reviewers, or senior members of this forum to elaborate in the near future. I turned up an earlier...

Antonio, glad to see you are staying involved. Wondering what TQ update you are alluding to. I'm not aware of any substantive firmware update since January 2023. With another year's experience and more bikes in use, I thought one would have come at around this time, with some beneficial...

Coincidentally I exhausted the battery on a 54 mile ride today, from a starting charge of 92%. Only 2150feet of vertical gain, but significant chunks of the ride were takenat aggressive speeds with liberal use of Eco, and occasional use of Mid where I would usually be in Eco. Oddly enough I...

I've tracked battery usage through September and the patterns are holding. Most of my rides fall into a1.2 to 1.6 ( % depletion / mileage) range so that 80% consumption will allow me to go 50-60 miles along local topography, which encompasses nearly all of my rides. Put simply, I don't have to...

I get more feedback than I need from the Karoo2 through the PC based Hammerhead dashboard, including battery % charge at start, end, and amount consumed at each level (except that it thinks E is lvl2, M lvl 4 and H lvl 7). I don't rely on max grade: stepping the bike over a curb throws it way...

Antonio, thanks for expanding the Domane+ SLR knowledge base. Post #41provides reassurance that the TQ motor and overall system are efficiently tuned. The overriding point I get from your post #40 is that battery charge consumption might go a bit under-reported early on, it ends up on the...

Quite understandable. Riding should be enjoyable, not punishing. I would imagine hub motor ebikes would come with narrower q factors. Have you tried the Domane+ AL5 or looked into carbon frames featuring the Mahle x20 and others? I haven't kept up with those but expect that they are also...

Any progress/improvement? Your best bet is likely to be a good fitting as Calcoaster suggests. Not the bike shop variety, but from a professional fitter with bio-mechanical expertise, like the guy in the attached clip, if you can get a hold of one within your reach. It's an expense, but the...

Just thought, backed up by scant knowledge, but have you matched the saddle position (relative to cranks) of your painless bikes? Have you tried switching the saddle with one from your other bikes?

Thanks to Antonio and Will for adding to the dearth of information from TQ on the HPR50. It's a shame that we have to sort these parameters on our own. Because my maximum sustainable heart rate and power are lower than Antonio's minimums, I'm very interested in figuring out how to get the most...

Apparently 96% Off/Eco was too easy for Antonio, had to go to 100%, and came out thinking he may need to trim back the support! Then again, he did make pretty good use of the available 84W and acknowledged finding the help on the climbs. The support drops below ~40W is a meaningful insight...

Will look into your rides tomorrow. This is good information that others will appreciate in the larger forum. You should post both rides there.

Great information. Much appreciated. It's bringing peak and nominal power into real world focus. 300W peak power for 6+ minutes on a scorching day seems pretty good. I was thinking it might keep it up for about 10 minutes on a cooler day, and it seems to be be within striking range...
