The FLUX 2 Smart is equipped with a bigger resistance unit compared to its predecessor, allowing for a wider simulation range. It is able to realistically simulate inclines up to 16% gradient.


A reliable, accurate and consistent power measurement is key to keep track of your performance and progress. This is exactly what the FLUX 2 Smart is designed for, it measures your power accurately within 2.5%.


A stronger resistance unit in combination with a larger flywheel significantly improved the ride feel and responsiveness of the FLUX 2 Smart. With these improvements, this Smart trainer better replicates the experience of outdoor rides.


The FLUX 2 Smart is designed to bring vibrations and noise levels to the absolute minimum. This resulted in a very silent flywheel equipped bike trainer.


By supplying the FLUX 2 Smart with additional axle adapters, the axle compatibility significantly increased. This direct drive is compatible with 142x12mm and 148x12mm axles, straight out of the box.


The smart electronics of this bike trainer allow you to train stand alone, without any software. It follows a progressive power curve, the resistance will increase progressively when you ride faster. Precisely replicating riding on a flat road.


Intuitive LED lights provide a visual confirmation when the trainer is powered and connected to a device over ANT+ or Bluetooth.


Designed to withstand the most intense training sessions, this bike trainer is built to last. A large footprint ensures maximum stability and durable materials give the quality you would expect

Great product, but horrible logistics and support from BOTS

Bought this trainer on 22 September 2020 and was delighted to see it is out for delivery on 24th itself. But the excitement was short-lived when status changed to wrong or incomplete address. Contacted Spoton logistics and send them an email with complete address and phone numbers. No luck for next 1 week despite daily follow-up with Spoton as well as BOTS. It was finally delivered on 01 October! All excitement of trying out the new trainer was dampened with this experience. BOTS should seriously reconsider their logistics partner. They should be able to deliver a parcel within Bangalore in 1-2 days time.
The product itself works very well so far. Very easy to setup ( Had to remove the cassette from my road bike- it doesn't come with a cassette) and comes with good software support ( Tacx and Zwift premium ) 1 month trial, after which you have to subscribe. But this trial of 1 month gives a good opportunity to try out both software and decide on your choice.

I would rate a 5 star for the product and website experience. But the logistics and support was a great disappointment.....

Sorry about that Manoj, we typically have quite an efficient delivery system for Bangalore but we had to use SpotOn since this was the only provided which seemed to ship to your pincode unfortunately. Will take your feedback on the shipping. Thank you.

Glad the trainer was awesome and that everything else was good. Wishing you plenty of training miles on the Tacx.
