Looks like Wahoo have just dropped some new tech.
It’s a total advert (and I’m totally not sponsored), but nevertheless it’s a pretty compelling demo:
It looks like the Kickr Bike Shift is the upgrade to the Kickr Bike, basically with the Kickr Move built right in.
£1400 for the trainer, and £2600 for the Bike.
I think if you are interested but don’t want to stump up for the full swap, you might consider a rocker plate? Personally I’ve not tried any of the Wahoo stuff, but I can say my now fairly ageing Tacx Neo 2 has a fair amount of movement in it. It doesn’t feel like an outdoor ride, but it gets the job done.
