Kinetic by Kurt Road Machine Indoor Bicycle Trainer for $271.19

The Kinetic Road Machine is the most popular trainer Kinetic makes and has become the company's go-to model for indoor workouts. The perfect workout partner for sprints to intervals to all-day cruising, the Road Machine is quiet, smooth, and, like every Kinetic Trainer, it's 100 percent leak-proof. The power calibration gives you true outdoor simulation while the automatic resistance adjusts as you change speeds. When the rear wheel spins on a fluid trainer, an impeller rotates through liquid to create resistance.
