When it comes to indoor cycling smart trainers, you have choices, which is why we created this 2021 Tacx smart trainer comparison. Tacx has been highly involved in cycling since 1957, first developing the NEO smart in 2015. Since the company was acquired by Garmin in 2019, the technology just keeps getting smarter! In this comparison article, we're looking at the Tacx NEO bike smart trainer and the Tacx NEO 2T, Tacx FLUX 2, and Tacx FLUX S smart trainers to help you decide how you want to continue training indoors while feeling like you're riding outdoors. You'll want to consider things like the weight of your smart trainer (the NEO smart bike is 100 lbs. heavy!) and how much power, accuracy, torque, and inertia you want to challenge yourself with. How much max incline do you want? Do you want simulation of descent? Take a look and compare these Tacx bike trainers that aren't just smart—we think they're brilliant!
