We are upgrading our gym exercise bike and considering a Wahoo Kickr

ideally an exercise bike with Kickr capability would be best but its just not available.

the obvious issue is, what bike do we fit to the Kickr ? would it be worth getting a custom frame with adjustable contact points if so who could do such a thing ?

Kickr nice but pricey. Also heard the power reported has a tendency to drift a bit.

I’d probably go for something cheaper with ANT control, like the new Tacx Smart ones and get a proper PM to control it. Could do it for about the same price as the Kickr.

You want something where you can change the position between riders? Might be tricky. You might be better off just getting something like a wattbike.
