Our Take
The Tacx Flow Smart is a wheel-on turbo trainer aimed at cyclists stepping up from basic rollers or dumb trainers. It sits in the entry-to-mid-level smart trainer bracket, offering ANT+ FE-C and Bluetooth connectivity for use with platforms like Zwift and Wahoo SYSTM, without the premium price of a direct-drive unit.
Key Features
Wheel-on design compatible with most road and mountain bikes via quick-release skewer
Dual wireless connectivity: ANT+ FE-C and Bluetooth Smart for simultaneous device pairing
Resistance controlled automatically by training apps when in ERG or sim mode
Maximum simulated gradient of around 6%, suitable for steady climbs but not steep virtual ascents
Power measurement built in, though accuracy is quoted at around ±5% — adequate for training, not race data
Foldable frame for reasonably compact storage between sessions
Our Verdict
A sensible first smart trainer for riders new to indoor training who want app connectivity without overspending. If you're training seriously for events or want accurate power data, stretch the budget to a direct-drive model. For occasional Zwift sessions and structured beginner plans, the Flow Smart does the job honestly.
