Hi @Stephen_Trap, welcome to the forums!
Jose here from Zwift. I appreciate your interest in our products!
We don’t have an exact date at the moment when they will be available. My advice would be to check our website periodically so that when they are available you can purchase yours. Also, on the page, if you see a button that says notify me, I would recommend that you press it so that you will be notified when they are available.
