Wattbike resistance not changing on hills

Hi everyone, I am using my new wattbike atom with my surface pro laptop. It’s all working fine apart from the wattbike isn’t changing the resistance on climbs or descents.

It’s got the latest firmware and I’ve tried everything suggested. Has anyone got any tips?

Hello! Are you doing free rides or workouts?

Free rides

I am also having issues with the resistance on the Atom Next Gen.

I can recreate the issue by selecting a flat route and slowly build up my cadence to around 70 rpm to warm up, but changing gears doesn’t make any difference to the resistance or the watts produced.
I can increase my cadence to 100 rpm and change up to 22nd gear and I am spinning out. The gears are showing on Zwift they are changing, but not the resistance.
If I push down hard on the peddles and increase my cadence quickly the resistance kicks in and the gears work properly.
I also get the same issue going down hills in Zwift where I am spinning out and the gears aren’t working and then when I hit the bottom of the hill and the gradient changes the resistance kick back in.

I have recreated the issue using 2 different ipads and a WIN10 laptop.

The bike is in an out-building which is 5 meters away from the house. There is only one other BT device in the building which is an Amazon Echo. The bike is about 3 meters away from the wi-fi point in the same room. I have a full wi-fi signal of 70mbps. I have closed all the apps on the Ipad.

Hi,

I am having the same issue with my Atom Next Gen, gears spinning out in gear 22. It was working fine for the first two weeks, nothing changed. Just suddenly now not working as it should. Is there ant fixes I can do?

I am having the same issues, bike was working fine for first 2/3 weeks and now it’s spinning out. Did you fix it?

I’ve tried different devices, updating firmware/devices, on off, checked internet etc but nothing

Zwift does not change the resistance you feel on hills, if you are using a Wattbike Atom running under Windows 10, with your bike paired to the PC via the PCs own Bluetooth. If you want to feel resistance (otherwise you would not have bought a smart bike), you need to pair via the Zwift Companion app instead - not with your PCs own internal Bluetooth. If you are lucky, you may be able to complete a ride without the ZC app losing the Bluetooth connection with your bike - though be careful, as this happens a lot (for me anyway, plus many other users on the forum).
I’ve done a lot of research into this and it seems that the ZC app is not good at recovering from dropped Bluetooth packets. I have been able to see (with a “Bluetooth Sniffer”) that ZC gives up at the slightest suggestion of packet loss, and is not able to reconnect. Everything I say here is my own opinion of course. I can’t see their source code, but it seems to me that it needs sorting out!
So,

  1. Try pairing via the ZC app, NOT directly with your PCs Bluetooth.
  2. Try to use 5GHz WiFi channels instead of 2.4 GHz to reduce the risk of Bluetooth packet interference.
  3. Try to limit the number of Bluetooth devices you are using in the vicinity of your bike.

Good luck.

I’m having the same issues too and can’t find any definitive answers on how to solve. I’ll try your suggestions here - thank you.

Had my Atom + Zwift for 3 weeks and I’ve had some great rides up until this week. I’ve given up this morning, had to cut a 45k ride short as it lost all resistance up the volcano :volcano: and I just had to spin to the top with my HR almost back down to resting :laughing: frustrating but there must be a fix out there.

For reference, I’ve been riding with Zwift on iPad Pro. Got a Bluetooth HR strap.

Anyone got any other suggestions or had any luck?

:pray:

@Jon_Raybould please can you tell me how to pair via the ZC app and not directly? I have exactly the same set up as you and can’t feel any change in resistance uphill.
