FAQ
Short answers
What is the best smart trainer for beginners?
For most beginners, a current direct-drive trainer with Bluetooth FTMS, stable ERG mode and a fair price is the safest choice. Budget models can work well if their power ceiling and accuracy limits match your workouts.
What is the best budget smart trainer?
The best budget pick depends on local stock and price. Look for Bluetooth FTMS, controllable resistance, enough max power for your intervals and clear return support.
What is the difference between direct drive and wheel-on trainers?
Direct-drive trainers replace the rear wheel and usually feel smoother, quieter and more accurate. Wheel-on trainers keep the rear wheel installed but can be louder and more sensitive to tyre pressure.
Do I need Bluetooth FTMS for Mini Watt?
Bluetooth FTMS is the cleanest Mini Watt starting point because it gives standard smart trainer control for ERG workouts and route simulation.
