Tacx Bike Smart Questions

I'll be moving to a Tacx Bike smart, and have a couple of quesitons:

Why would you need a bike computer for an indoor trainer?

Cam you use the Apple watch to track pulse rate when using zwift?

You don't need a bike computer for indoor training, especially not with a smart bike.

I don't think Apple broadcasts HR via the usual standard protocols, so I think it's a no on that one. I use a Polar OH1 armband HRM with Zwift etc.

Apple Watch will track HR itself if you activate a workout logging session on the watch. Pete, above, is correct, the Apple Watch does not broadcast. Generally, folks use a separate sensor for integrating HR data into ride data for viewing on Strava or Garmin Connect or some other aggregating site. I use a Wahoo Tickr-X on the bike, in parallel to the Apple Watch.

No need for the computer, but I have heard of some running the bike computer in parallel and using it to upload non-duplicative data (on bike power meter for L/R power or avg watts, for example) somewhere other than where Zwift data is sent.

Basically its more advanced stuff. I dnot bother with it.

If you were using an outdoor bike with its own power meter on a smart trainer then you might log the bike's power meter on a Garmin (or whatever head unit) in parallel to the trainer's own power data recorded directly by Zwift. I've done that myself to compare indoor vs outdoor power measurement. But if using a complete smart bike then a separate bike computer is then totally redundant unless you were planning to use the head unit to actually control the smart bike instead of a pc/tablet/smart phone. Not much point in that really with a dedicated indoor setup.

Here's my example from the "not much point in that really" club (what PeteHski says is correct, but I do it anyway).
Channel 1: Wahoo Kickr Core talking to Zwift running on iPad (very current model). Zwift keeps all performance data, exports to Strava for "aggregation"
Channel 2: Wahoo Kickr Core talking to Garmin 130 plus head unit. Gives me more in-ride data, like average watts and total work. Garmin also used for outside riding with Garmin Rally SPD power meter pedal. Both indoor and outdoor on Garmin Connect, auto export to Strava for consolidation.
Channel 3: Apple watch records independently, just for seeing total daily stuff, includes couple miles of walking each day.
Not cycling: Also use logging software for Concept2 rowing machine, goes to Strava for consolidation.
Too complex? Took a little while to figure out if I cared about all that, but now it's seemless/frictionless. sometimes, not always, have duplicate entries from Zwift and Garmin Connect to clean up, but other wise quite easy. Hop on, flip on the powerstrip, start Garmin, start Zwift, start watch, ride. Just a numbers geek at heart. Alas.

If you are riding outside a Garmin makes a lot of sense and then also using it indoors for an additional in-ride "stats" page is an easy thing to do if you can be bothered. But if you are only riding indoors with a full bells-and-whistles smart bike then a Garmin head unit would be a waste of money unless live average Zwift wattage was considered vital. Just to clarify for the OP, Zwift doesn't currently display your running average power during a ride.

I'll be indoors only, and I don't care about a running average on power, so...

I'll pass on a bike computer.
