You don’t need a ‘smart’ trainer. A normal one is perfectly fine but you just need to weigh up if it’s worth the extra expense to have the resistance change with terrain. I tried on my ‘dumb’ trainer for a while and to be honest, it was fine. But the auto-resistance changing is better & makes it more immersive. Your legs also get a more realistic workout I reckon….
Other things you will need:
Check your laptop handles the min specs or thereabouts. Mine fails on the graphics spec, but still works fine. It stutters if a massive group of riders come past (race start for example), but 99% of the time it is not an issue.
Suitable Wi-Fi connection in your location.
Ant+ dongle
Ant+ speed/cadence sensor
I already had a HRM so use it, but you don’t need one. I like keeping track of my heart rate.
Wheel block if the turbo doesn’t include one.
Nice to have:
Towel thong for bike
Large pedestal fan….(especially with the weather warming up).
