2. SMART TRAINER + ORDINARY BIKE

It's a must that also the resistance of the smart trainer can be controlled by Zwift. These are smart trainers that should work very good, and all are of the wheel-off type:

  • Wahoo Kickr Core
  • Wahoo Kickr V6
  • Tacx Flux 
  • Tacx Neo
  • Elite Suito
  • Elite Direto

As a lower budget solution you can also start with a wheel-on trainer like the Wahoo Kickr Snap. 

Choose whatever best offer you find in the country you live.
