They have probably managed to mitigate that noise quite a bit, but it's still there and can occur under certain pedaling conditions. For now, I tend to think it's something intrinsic to the TQ motor and that one can learn to avoid the conditions that trigger it. Apart from that, I still love my...

I am tricking the motor. I don't allow the assistance power to drop to low levels where the grinding noise occurs. I achieve this by quickly shifting to higher gears so that my legs are always delivering power. Also, on easy segments of the route, I turn off the motor.

Jack, to be honest with you, I've been very satisfied with the performance of the 2023 Domane+ SLR. It's the ideal road e-bike. Regarding the grinding noise and based on TQ's response, it reassures me a bit, and for now, I'll try to avoid the pedaling and assistance conditions that trigger it...

Jack, it's exactly the grinding sound they describe in that forum.

Searching a bit in various forums, especially in MTB forums that use the TQ50 motor, I come across the fact that this same issue is well-known to them, and they have even received a response from the manufacturer clarifying their stance. I am attaching a YouTube link where I found the following...

Thank you, Stefan. I understand what you're saying, and I find it very valid. What generally catches my attention is that if, indeed, at low assistance demand the motor doesn't perform well, why don't they restrict those configuration zones via software?

Thank you, Stefan, for sharing your observation related to the Specialized SL. It seems to be a similar behavior. How have you resolved it in your case?

Thank you, Jack, for your timely comment. I suppose you're referring to the ring that secures the chain sprocket to the motor shaft?. I will check.

Grinding Noise What seemed perfect ceased to be so. My odometer has crossed the 1000 km mark, and in the last three rides, a terrifying noise started coming from the TQ50 motor of my 2023 Domane+ SLR. For a moment, I thought some mechanism inside the engine was being ground because it was an...

Hello Rob, I'm glad to hear that you started to enjoy the Domane+ SLR. Collecting data from our rides is crucial to understanding the Domane+/HQ50 system. This knowledge will enable us to use the battery efficiently, resulting in longer and more challenging trips. I like the approach you're...

As I mentioned earlier, my first experience with an ebike was with an Orbea Gain D50 with a rear hub motor, based on the Mahle X35 system with a 250WH battery and a 40NM motor. The total weight of the Orbea is around 13.1 Kg. Rear hub motor ebikes have some particular characteristics that make...

One of the concerns when planning a route on an EBike is knowing whether the battery's charging capacity will be sufficient for that journey. Naturally, the battery's capacity will depend on many factors that we are all already familiar with. Knowing that the 2023 Domane+ SLR has a battery with...

Hello Moss, Some time ago, I installed the X35+ motor on an aluminum DT Swiss wheel, and I've been using it without any issues since then. The rim I used is the R460 700C 23MM DB VI. In addition to the rim, you'll need to get spokes of the appropriate size. In my case, I used DT Swiss spokes...

Hello Plumm Bob, you are experiencing what many of us have suffered with this application. There's no doubt that the Mahle X35 system is an excellent system, I have no complaints, but the My Smart app is really poor. I got tired of it and opted to stop using it quite a while ago. I only use my...

Rob, you are correct. I have an Orbea Gain with a rear hub motor. The front end is standard Shimano or Sram (in my case Shimano 105).
