Tacx Neo 2 - first impression

Post by Sebman » Wed Dec 05, 2018 9:20 pm

Good evening all

I have replaced my Genius Smart with a Neo 2 yesterday. I am super happy with it and I am impressed how quiet it is compared to the Genius. So 100 points for the Neo here. When it comes to the firmware I guess there is still room for improvement. I have a lot dropouts and freezes when it comes to the cadence. So for the cadence I use the external sensor which is installed directly at the crank arm instead. I have to mention that I am using Zwift. Further the connection with Bluetooth and my MacBook Pro (Mid 2015) is really weak and when I restart Zwift I can’t connect via Bluetooth or even can’t find the Neo at all. Ant+ is without any issue.

Is anybody having the same experience?

Ride on, Sebman

Some have reported issues using their computers embedded blue tooth controllers for which the most discussed workaround was to purchase a 3rd party USB Bluetooth receiver. Regardless of whether using the embedded or an external receiver, it is important to disable power management for USB and Bluetooth, otherwise Windows has a nasty habit of powering off devices it considers not to be in use.

Through some experimentation and feedback from others, the Asus BT400 or similar transmitter with a Broadcom chipset seems the most reliable so far. There are many BT transmitters with CSR (Qualcomm) chipsets. I have found the Broadcom to be more reliable on initial connecting in TDA and connecting after a Speed/Cadence and Power sensor have gone to sleep and then awoken. I have had some instances of Asus BT400 connection problems, but they have been a lot less than BT transmitters with CSR (Qualcomm) chipsets.

This does not reflect any detailed testing. It is just my personal experience, which others I know have also experienced.

Many thanks for your answer, they are very helpful. I am not a pro with Bluetooth topics but thought these are sort of standardized protocols and should work with any receiver that has them installed. Ok then, I stick with ant+ because my heart rate monitor is ant+ anyway. More annoying is the cadence thing which should be fixed with an update soon.

The user replaced the Genius Smart with Neo2, and you tell him about the problems of USB Bluetooth transmitters. That's obviously not the point.

The OP did mention issues with bluetooth which I took the track as possibly being the cause for the cadence dropots, therefore my answer was based on the assumption that the OP might be running a Windows emulator like Boot Camp on his mac:

Yes, thank you, but still it seems that the situation of the user has deteriorated with the transition to Neo2. He shares here with new problems. Not so?

I think you raise a reasonable question Alex, but given his reported Bluetooth concerns, I think a good starting point is the onboard Bluetooth transmitter. If that is a bit marginal, you could have different results with the Neo and Genius. External Bluetooth transmitters are pretty cheap. But it could also be something else.

@Sebman

I fixed the cadence issue by extending my left pedal a bit. I taped a little metal plate to the inside of my left pedal where the sensor is located behind the neo 2 label.

Many thanks ejl888, I will check if this works! Because i am using a cross bike on the Tacx, not a race bike, it’s maybe because of the chainstray that causes interferences. Otherwise I stick with the external sensor, this works very well without any issue.

While I applaud the ingenuity exposed above, I have to ask exactly how did you come to the conclusion that there is a cadence sensor behind the Neo 2 label? What happens when you turn the cranks of the bike by hand using only the pedal and compare using the Tacx Utility app? While you would probably need to generate at least 30-rpm of cadence, you should readily see cadence values corresponding to the speed of the cranks. Take a look at GP Lama's Tacx Factory tour video and about the 5 minute mark you will see the construction of the Neo as well as the test stand that Tacx uses to calibrate the Neo, and note that this is all done from the drive side, the test stand has nothing on the non-drive side of the trainer. The point is that if your Neo does not reliably generate cadence while riding using something other than TTS 4 or TDA, then the issue is probably with the application.

Hi,

today I have received my neo 2, had the flux 1 before. With flux there were no issues with the cadence, with the neo 2 I have exactly the same as the OP. I'm connected to a MacPro via Bluetooth. I have tried connect with Bluetooth, with companion and connect directly to zwift app on iPhone same dropouts. Cadence is from 0 to 160 changing every second.

But if I connect to the tacx utility app, it shows the cadence right. Also with Tacx training app it is ok. Only with zwift are droputs there.

So there must be a problem with zwift. Tomorrow I will get my ANT+ USB Stick I will try with this.

Having just read DCR's Neo 2 In Depth Review, sure would be nice if Tacx would make the circled thru-axle adapters available for purchase for Neo 1 owners as it appears these new adapters are intended to be threaded into the frame.

GPLama has taken another tour of the Tacx Factory, this time focusing on the Neo 2 and from the image below, and from what I can see, I may owe a previous poster an apology as there now is definitely a PCB behind the Neo 2 label. While this would apparently coincide with the sensing of the riders pedal/shoe position, based on the minimal amount of chips on that board I fail to understand how this could contribute to the sensing of the riders shoe/pedal position, especially considering the NDS cover is not even installed on the test stand.
