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.
