Indoor cycling smart trainers have been training staples for serious cyclists for several years now. But the pandemic did much to bring indoor cycling smart trainers into the mainstream for more casual cyclists looking to continue exercising indoors through the winter. When connected to a virtual cycling environment like Zwift, indoor cycling smart trainers can make the indoor riding experience far more engaging and efficient. Smart trainers connect to external devices like computers, laptops, and phones to open up capabilities that regular trainers can’t deliver. An indoor cycling smart trainer is a device that supports your bicycle and allows you to ride it indoors. It also communicates via wireless signal — usually ANT+ and/or Bluetooth — to a computer so you can use web-based cycling programs like Zwift, Rouvy, and other software. The point of an indoor cycling smart trainer is to add more dimensions to indoor riding. Non-smart trainers were the norm for many years, and while these allowed riders to ride their own bikes indoors in a stationary position, they did not communicate at all with any external devices.
