No Resistance Rebook FR30 Sprint

Hello I’m new to Zwift and have been having a pretty good experience so far. Today I was riding the route Tick Tock and experienced resistance lag in the flat areas of the route. I rode it twice and it occurred in the same areas. Very frustrating when the resistance doesn’t adjust and I’m stuck going slow.

I’m not sure what you mean by resistance lag. In simulation mode, on a flat road, Zwift would not be telling the trainer to change resistance. Were you doing an ERG mode workout?

Unfortunately no Reebok products are supported by Zwift so if the bike has compatibility problems, you would need to discuss that with Reebok. The manufacturer claims it’s compatible, but Zwift says nothing about that. From their perspective, the trainer is untested.

I understand the risk I took with an unsupported untested product. This post is more of a “hey Zwift take a look at what the route Tick Tock does at the flat sections” usually when riding and I change the cadence Zwift responds with more or less resistance. In those areas nothing happens like you said and for the end user experience it sucks. Just trying to put a nice post out there to help Zwift be it’s best.

I wonder if the problem you’re experiencing is the same as this issue that was reported in January…

If the problem you’re reporting were confirmed by anyone with a supported trainer, I would expect it would get fixed eventually, but it seems to be unique to that bike.

The other option you have is to try using the QZ app as a bridge to pair the FR30 to Zwift. @Roberto_Viola is the developer, and he is the most experienced person at fixing strange problems with unsupported spin bikes via his app. I don’t know if that would help, but if it would make your rides more enjoyable it might be worth trying.

I don’t use the same reebok bike as you, but I’ve also never experienced this issue you are explaining.

Why would increasing cadence on a flat road also increase resistance? That doesn’t make sense to me.

Let me know if I can help you

I do a lot of similar controls work in my line of work. (Test Engineer) Now on a spin bike you have no gears so if you want to make work happen (resistance) you need an input (cadence) if cadence is baselined and averaged and the average is starting to increase then resistance would be increased to try to bring the cadence back to the previous average. The increase resistance is more watts watts over time are converted to speed.

I have an update for everyone. Today I rode the route out and back again and experienced the issue with resistance. I have a Garmin Vivoactive 4 and I wanted to use the heart rate sensor from it with Zwift. I figured out that the watch broadcasts the heart rate over ANT+. I run Zwift on a Galaxy A9+ tablet and it doesn’t have ANT so I bought a dongle for it and was able to get the heart rate to work. While riding I removed the ANT dongle and just like that resistance response was greatly improved. Put it back in and eventually resistance updates would stop. Take it back out back to expected response. So do I have cross talk going on? Not sure at this point.

I also can’t figure out bridging but bridging doesn’t solve my issues because the phone can’t find my heart rate sensor when pairing devices in Zwift.

So I have the fr30 and also have found it extremely frustrating that the bike seems to get confused by zwift constantly changing the resistance. The last two rides I have plugged the bike in and connected to zwift then started a ride I then unplug the bike and then plug it back in at the electric. The bike re connects to zwift but then allows me to use the dial to change the resistance and therefore the watts I’m outputting. I’ve also turned off the resistance change for hills etc
