Thanks for the answers, now I do understand more, but still need some important information…

All the prices are highly misleading on the web, but it looks that:

“Real Turbo Muin” can do the work, but the price is well above 1000 USD (maybe 1500); there is a confusion on the market with “Turbo Muin Smart B+” (range 500 USD) that look pretty much the same but does not have dynamic variable resistance.

Wahoo “KICKR SNAP Bike Trainer” also can do the work, but the price is in the range of 750-800 USD, sensors not included; it is not clear whether the software and Windows PC communication is included in this price.

Tacx Vortex ($400+) or Bushido ($500+) can also do the work with dynamic variable resistance. However, further $150+ should be spent for PC connection and for Tacx software. So, the real price is $550+ for Vortex and $650+ for Bushido. Furthermore, around $65 per year should be spent to “ride” online on their platform, or $45 to “ride” on google maps. It still looks the cheapest, however:

If I start by buying Tacx Bushido standard package ($500+) without PC connection kit ($150+), what can I achieve with that?

Does it have speed and cadence sensors?
Does it have a screen or connection to Android smartphone, to monitor parameters?
Is there any kind of video interaction and automatic management of the resistance according to it – on Windows PC or at least on Android smartphone?

Thanks,
