This doesn’t quite answer your question, but I picked up a Kickr Bike v1 last year when they were heavily discounted (just before v2 came out). As far as I can tell, the only real advantage v2 has is the wi-fi/direct connect, and that easily wasn’t worth an extra $1400 to me. The bluetooth connection has been really solid for me, I don’t think I’ve ever even had the connection drop out. v2 also has a higher maximum wattage, but you won’t need it unless you’re regularly busting out 2200w+ sprints (in which case you probably get your equipment for free ). I’d say go with v1 if you’re getting a good deal on it.
If that’s only available over wi-fi/direct connect, it won’t be added to the v1 bike. I only race occasionally (and very badly ) so still not worth the extra $ for me. It’s not necessary for freeriding and ERG workouts.
