Would love it if this game would be available on Schwinn treadmills. Hopefully one day and sometime soon it will happen.
Please make it happen zwift

If you are talking about the treadmill having the ability to broadcast speed directly to Zwift using Bluetooth Schwinn would need to make it possible.

You can use Zwift with any treadmill, you just need a run pod like ZwiftPod, Stryd, Garmin and so on.
