Overview

The Tacx Neo 3M is Garmin’s flagship direct-drive smart trainer, designed to deliver a premium indoor riding experience. While it excels in power accuracy and ride feel — with standout ERG mode performance — it falls behind on modern features and compatibility. At $1,999, the value proposition is hard to justify in a competitive trainer market offering more for less.

Ride Impressions

There’s no questioning the Tacx Neo 3M’s power accuracy and pedaling feel — it’s top of class. ERG mode transitions are buttery smooth, and surface feedback through the pedals adds an immersive touch. Unfortunately, sprinting on the built-in motion system feels awkward, and the derailleur clearance issue may frustrate less experienced users.

It’s a trainer that feels brilliant under load, but lacks the modern creature comforts now expected in this price tier.

Best For

• Data-driven riders and serious indoor trainers
• ERG mode-focused interval athletes (TrainerRoad, Zwift workouts)
• Users with 11-speed Shimano drivetrains

Verdict

The Tacx Neo 3M delivers one of the smoothest, most accurate rides in the smart trainer category — but it’s also the most expensive. Lack of WiFi, no cassette choice, derailleur clearance issues, and awkward motion plate performance leave it behind the competition. A premium option that feels unfinished.
