Garmin Tacx NEO 3M review
Built in motion plates, a virtual flywheel and no calibration ever, for eighteen hundred dollars.
A direct drive smart trainer with built in integrated motion plates that can be toggled on and off, a virtual flywheel simulating road surfaces, gradient simulation to 25 percent and descent simulation.

What it does well
- Motion plates built into the frame let the bike move laterally as you pedal, which is the single biggest comfort difference on rides over an hour and the reason people finish long indoor sessions.
- Descent simulation actively drives the drivetrain on downhills, which no other approach replicates and which keeps a virtual descent from being a rest.
- The NEO family needs no calibration because the resistance is measured electromagnetically rather than inferred from a belt, so power is consistent from the first pedal stroke.
- Road surface simulation through the virtual flywheel is a gimmick until you ride cobbles in a virtual race and discover it is genuinely unpleasant, which is the point.
Where it falls short
- Eighteen hundred dollars is the top of the market, and the training benefit over a trainer at half the price is comfort rather than accuracy.
- Motion plates add height and take floor space, and the unit is heavy to move.
- Descent simulation and road feel need power at the trainer, so this is not a portable or race day warm up unit.
- Direct drive means you remove your rear wheel and need a cassette, which is a cost and a job most owners only want to do once.
What owners report
Published owner reports single out the motion plates as the feature that changed how long they could ride indoors, which is exactly the benefit Garmin claims. Power consistency and the absence of calibration draw repeated praise.
The criticism is price, and it is fair. Reports comparing the NEO 3M with the 2T generally describe the difference as comfort and refinement rather than better training data, which is the honest framing for anyone deciding.
Who it suits
- Riders doing long indoor sessions where comfort determines whether the ride finishes.
- Anyone who wants power data with no calibration routine.
- Zwift racers who want road surface and descent behaviour to be realistic.
Who should skip it
- Riders doing short indoor sessions, where a cheaper trainer trains identically.
- Anyone short of floor space or who needs to move the trainer often.
- Cyclists who would rather put the difference into a power meter that works outdoors too.
Alternatives worth considering
The same electromagnetic resistance and calibration free power in the previous generation, without the built in motion plates. The training is identical; the comfort over three hours is not.
Check Backcountry → Check price on AmazonOver 2,200 watts of resistance accurate to within one percent, with WiFi for instant data transfer and AXIS feet for a little side to side movement. Less refined road feel, and it does the same training.
Check Backcountry → Check price on AmazonA quarter of the NEO 3M's price, and it ships with the Zwift Cog so you do not have to buy and fit a cassette. The sensible entry point into direct drive training.

Common questions
Do motion plates actually help?
For long rides, yes, and owner reports are consistent on it. A bike locked rigidly in place forces the rider to absorb every pedal stroke through the same contact points, and lateral movement relieves that. On a forty minute session you may not notice; on a three hour Zwift ride you will.
Does the NEO need calibration?
No, and that is a genuine advantage of the design. Resistance is applied and measured electromagnetically rather than through a belt, so there is no spin down routine and no drift as the unit warms up. Trainers that need calibration produce inconsistent numbers when people forget.
NEO 3M or NEO 2T?
The 3M adds built in motion plates and refinement. Power accuracy and training capability are effectively the same. If you ride long indoor sessions the comfort is worth real money; if you ride short ones, the 2T saves seven hundred dollars.
Smart trainer or power meter?
A power meter measures your actual output on your bike, indoors and outdoors, and travels with you. A smart trainer controls resistance for structured indoor workouts. Most serious riders eventually want both. Our power meter versus smart trainer comparison sets out which to buy first.
What is descent simulation?
The trainer drives the drivetrain forward on downhill sections rather than simply removing resistance, so a virtual descent feels like freewheeling downhill rather than like stopping pedalling. It matters most in virtual racing, where descents are where positions change.
