Why We Like The Flux 2 Smart Trainer
Winter's brutally cold weather conditions and lack of daylight all contribute to a waning desire to ride outdoors. Riding the trainer inside isn't exactly on our list of favorite activities, but the Flux 2 Smart Trainer does a wonderful job of simulating road feel. Utilizing a heavier flywheel and stronger electromagnets, this updated trainer better simulates the load you would experience on a typical road ride. Boasting compatibility with many third-party apps, the Flux 2 can pair with virtually any smartphone, tablet or computer, transforming the indoor riding experience this winter.

I love it!

Purchased the Tacx Flux 2 for the option to ride indoors and try Zwift. It was super easy to set up. The trainer is well built and quiet. I was on Zwift in just a few minutes and have only ridden outside once in the past week :). Looks to be a good alternative to riding in the summer Florida heat.

Nothing but headaches

I regret buying this. It has been nothing but a headache. Constant connection problems. I've barely been able to complete a single training session without the bluetooth dropping. It will either not connect at all or drop the connection halfway through the ride. I'm quite tech savvy and have been through every troubleshooting scenario I could find. The ride videos on the app are nice, but what's the point when you can't finish a ride? Same problems regardless of device.

Great value

I describe this as having the right balance between features and price. I've done 250 miles and have been very satisfied so far. I'm not a bike mechanic by any stretch and was able to get it set up in less than 15-minutes. It's quiet, easy to use, and has worked seamlessly with Zwift.

Solid Trainer, But Poor Training App
- Familiarity:
- I've put it through the wringer
If you're looking for a manually controlled trainer, then the Tacx Flux 2 Smart Trainer works perfectly. It's super quiet and has a wide resistance range. It was very easy to setup. And, it was even compatible out-of-the-box with my 27.5 inch Boost mountain bike frame. Now the bad news...the Tacx app is horrible. If you think you're going to connect the app to the trainer and then quickly run their training videos, then you're sadly mistaken. Even after using the app daily for three weeks, I was still struggling to get it all working correctly. Some days, the connection to the trainer wouldn't work. Other days, the connection would drop out during the training session. When it did run smoothly (75% of the time), the videos on the app would control the resistance oddly. On long, constant pitch climbs in the Alps, the resistance would suddenly change dramatically harder or easier like the rider who created the video shifted gears. It was so bad across all videos that I had to modify the settings of the app to reduce the power by 50%! Even on flat rides, there would be this "gear changes". I'm surprised that Tacx (owned by Garmin) wouldn't have removed these dramatic power changes from the videos -- it can't be that difficult to identify the large spikes and level them out. In addition, there are very few videos that are oriented to mountain bikers. Maybe only a half dozen. Certainly no singletrack, but there are a few gravel path rides. Most of the videos are paved road rides. So, after a month of using the trainer daily, I've now stopped using the Flux app completely and just control resistance from my Garmin GPS while watching YouTube mountain biking videos. So much less hassle and the trainer works perfectly while staying connected.
