Weight wise the Neo 2 comes in at 47.3lbs, just below most airline’s 50lbs luggage limits. The Basics:

Erg mode workouts are perfect: Erg mode in small ring and mid cassette are great. TrainerRoad workouts are excellent and spot on power. Power lines up with my P1 pedals within the margin of error and are consistent (in my case 3-6 watts) Whereas in the case of the NEO 2, the internals have been significantly refreshed. Albeit that hasn’t resulted in much in the way of new features for us end users. Instead, it’s more about the promise of unknown new stuff down the road. Sound-wise there’s no appreciable difference between the Neo 1 and Neo 2 – they’re both silent-ish. I say ‘ish’, because there’s still the noise/sound of the drivetrain (meaning, your bike’s chain and gears), so that exists. But the sound of that will be tied directly to how clean you keep/maintain it. After sliding the cassette on, just validate it doesn’t wiggle any. If it wiggles, then something is amiss (either it’s not tightened properly or if on a 9/10 speed cassette then a spacer is likely missing). The Tacx Neo 2T is physically shaped by a unique design that doesn't use a flywheel (Image credit: Josh Ross)Bluetooth Smart Tacx Trainer Control: This is Tacx’s private method of controlling the trainer. At this point it does NOT yet support FTMS, but that switch-over is very near term according to the company. Most apps support this Tacx method, so it’s not a huge deal at this point in time. Suitable axles - Width of rear fork: Race 130 mm, MTB 135 mm, 142 mm & 148 mm. Adapter for 135 x 10 mm available. ERG Mode: Setting a specific power level – i.e., 230w. In this mode, no matter what gearing you use, the trainer will simply stay at 230w (or whatever you set it to). The other standout feature of the Tacx Neo 2T is road feel and it's another feature that's only possible because of the direct connection to the motor. This is a feature that you can't buy from anyone else at any price point and it's really as simple as a pulsation of the motor in a variety of specific ways. As you ride over cobbles, or gravel, in Zwift the Tacx trainer will shudder in a way that does a remarkably good job of simulating the feel of real-life cobbles or gravel. Next, while Tacx does have a mobile app for their trainer, it’s unlikely you’re going to use it much if you use other 3rd party software. However, it is valuable for setting your correct weight so that you can get realistic grade simulation (as well as firmware updates). Do note that this is super important when using the Tacx NEO series over Bluetooth Smart with trainer apps like Zwift.

ANT+ FE-C Control: This is for controlling the trainer via ANT+ from apps and head units. Read tons about it here. This trainer has made riding indoors on Zwift fun, well realistic. I use it in conjunction with my MacBook Air and have had no problems with it. Thanks to its powerful motor brake, the NEO 2 SE can brake up to 2200 watts of power at 40 km/h and simulate up to 25% incline. This makes it ideal for even the most intense forms of training, and the rider is the only limiting element. Once clipped in on the bike, the unit feels extremely stable and the ride feel is superb. Not only does it feel better than most of the competition, the Neo 2T simulates a wide range of surfaces including regular roads, cobblestones, gravel and dirt roads. When used with Tacx Films or Zwift, this provides a truly unique ride experience, and in a positive way. Note that Tacx has a complete suite of training apps that they sell like other 3rd party app providers do. What’s notable about that is that’s where you’ll be able to see the pedaling metrics these days. Tacx says that’s coming to 3rd party apps soonish (and also likely via the ANT+ standards around it too). But today that advanced data is only shown in the Tacx app – and frankly, very few of you are using that (I’m not one of those people either).For me, in my testing, I used Zwift and TrainerRoad as my two main apps (which are the two main apps I use personally), with a side dish of SufferFest for this round of testing. In the case of Zwift, I used it in regular riding mode (non-workout mode), whereas in the case of TrainerRoad I used it in a structured workout mode. For SufferFest it was in ERG mode. I dig into the nuances of these both within the power accuracy section. Here you can see the NEO paired as an ANT+ FE-C trainer (and as a cadence sensor) with Windows: Beyond the aforementioned issues, setup is extremely easy, the connectivity is excellent, the accuracy is great, and the specs are excellent. The one area I have seen challenges with though is if the trainer is at a low speed (such as a low-speed climb), and then I apply a significant sprint-like force to the pedals, it’ll slip. By ‘slip’, I mean it feels like for a split second you out-power the trainer. As if you pulled too fast on the toilet paper roll and things went flying. Via a capacitive sensor on the left and right side, the NEO 2 detects the exact position of the legs while pedaling. In combination with the power meter, an exact analysis of the power distribution can be made. With this data, you can specifically optimize your pedaling and compensate for any imbalances.
