The Tacx Boost is the best option for a non-smart trainer if you still want to train with third-party apps. The Boost has a lever to change the resistance of the flywheel manually that clamps to your handlebars.
The bundle comes with a speed sensor and if you add a cadence sensor you can ride on Zwift using Z-power.
The Tacx boost is a wheel on trainer and has settings for three different wheel sizes. It also has a fully enclosed resistance unit meaning that it is quieter than the average wheel-on trainer.
