Built to deliver the optimum indoor cycling experience, the adidas C-21x features a large 16 kg / 35 lb rear-drive flywheel, designed to simulate the feeling of an outdoor bike by storing kinetic energy and maintaining momentum for a smooth cycling motion and consistent cadence. Take control over the intensity of your ride by shifting the 8-level resistance paddle to lower or increase the energy required for each pedal stroke. Further enhance your training regime by syncing the C-21x with Zwift, an immersive online experience built around a connected global community of cyclists. Also compatible with Kinomap, take part in a whole host of challenges and scenic motion videos or even compete with your friends in multiplayer mode.
