No that sounds correct to me, Garmin doesn't use power to calculate speed it uses rpm and circumference.
Have you managed to successfully add the bike's power/cadence as a sensor to your garmin? That's what I do with my SB20, and my Epix can then display the live watts during an activity. The Garmin estimate of speed / distance differs a bit from Zwift's figures, and I guess the main reason is that the Epix doesn't know about gradient.
Sounds like a bike issue, or the speed it's calculating from flywheel, as the flywheel isn't spinning any 'faster' you're not seeing any increase in your speed, even though the resistance is increasing. Either faulty or just the issue with that kind of 'smart' (but not really smart) spin bike. It's just not designed around Zwifting/power based training. Just designed as an electronic home version of a spin bike.Used the Decathlon bike yesterday whilst watching the United game - Double punishment!. There definitely feels like something is wrong in both speed and power readings. The lack of ability to input weight is probably a factor on speed as it regularly says i'm doing 37kph whilst just easily spinning at 150w. Then it doesn't export the cadence to my Garmin and so that reads speeds of 11.7kph pretty much consistently. As such i end up with stupid workout recordings like this (although it is showing cadence which is likely to be accurate. It just doesn't display on my Garmin device during the activity)

It's a shame Wahoo charge so much for delivery really. I would've gone with one of their Reconditioned ones at €2000 but with €150 for delivery, it's not far off the bike new at some third part retailers at €2300.
You've made a good choice, pretty sure you'll find it night and day compared to the Decathlon bike!
A friend who has an SB20 in Portugal recently got a replacement (new) crank arm for one of hers which wouldn't stay calibrated. So you can certainly still get them!
Garmin never estimates speed from watts. Only rpm and wheel size/circumference, or speed.Have you managed to successfully add the bike's power/cadence as a sensor to your garmin?

If it is paired, then the only thing I can think of is that it's also sending duff speed/cadence data and Garmin is using this somehow instead of estimating speed based upon Watts.
This might be relevant: https://www.reddit.com/r/Garmin/comments/1cb0fe8/new_smart_bike_cadence_way_too_low/ - I didn't spot any solution in there though.
It might be worth trying BT instead of ANT+ (or vice versa), and maybe deleting the 'trainer' sensor and seeing if you can add it as a power meter sensor instead?
Or just wait until your new Kickr turns up
Interesting, thanks - I wrongly assumed it was based on power.
Good to know - Saddleback do (did) the UK support and would be the first place to call.
With power and weight you could estimate speed/distance on level ground (a simplified version of what Zwift does). But it's a bit academic if Garmin doesn't do it this way
Strava is so dumb. Why is this a thing like that.Top tip (that I only learned a month ago). If you are in a group ride or you stay with someone indoors or out long enough and strava thinks you rode with them, press manage group and give your iPhone a shake. There’s a pop up that allows you to give everyone in the group kudos with a single button press allowing you to be polite and lazy both exactly at the same time
Just makes it a bit easier to give kudos to those you arent following. I think its a decent feature tbh
No it is, but why is it hidden like that.
