As I said above, wired units are obsolete. My journey in bike electronics started with my Wahoo Bolt, and once I started there I found that everything else just worked within the environment. I added a smart trainer, got an ANT+ dongle for the computer, use RWGPS to map out routes that just show up on the computer. My rides appear in RWGPS or Strava (I use RWGPS to track) when I'm done with the only intervention being to hit "Stop" on the computer. It captures GPS as soon as I'm outside the house, sometimes inside too. It shows my texts and calls on my phone. It just integrates with everything and wirelessly. I use my Bolt on two different bikes and it adapts to the bike it is on without setting anything. It uses GPS speed on my MTB because I'm too lazy to swap the wheel sensor, and too cheap to buy another. It works with Zwift, Sufferfest, Rouvy, etc.. It'll show the gear you are in if you have electronic shifting. It'll toast and butter your bread.

A feature I thought of that I don't think it does is show hydration levels. It would be great if it could tell you when you are getting dehydrated before you start to feel it.

The Coospo unit may or may not do everything I just said, but my guess is that since it is wireless it will do a lot. It uses the standard protocols.

A wired unit will work with the bike it is on, with a wheel and pedal sensor. And that's it.

Anyway, my point is with wireless you are buying into the ecosystem of electronic gadgets. You may not think you need it, but once you have it you find a lot of uses for it.
