Built to deliver the optimum indoor cycling experience, the Adidas C-21x features a large 16 kg 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. Manually adjustable, without having to cycle through incremental levels, the resistance paddle allows you to quickly tailor your spin workouts with ease.

With the internal self-generating motor, you are the one that creates energy and powers the C-21x’s impressive features. No need for a power adapter, tangled wires or restrictive plug sockets, you have the power and freedom to train anywhere in your home. With built-in transport wheels and grip bar, it’s even easier to move the bike around your home as you wish.

The C-21x’s onboard computer delivers live performance metrics including speed, time, distance, calories, pulse and RPM. Using the supplied chest strap, you can also monitor your heart rate and receive accurate data on your performance so you can track your progress. A tablet and smartphone holder has been integrated into the design of the console so that you can easily watch video content whilst you cycle.

Some features that the Adidas C-21x comes with are fully adjustable handlebar setup with armrests, horizontal and vertical saddle adjustment, streamlined sprint saddle and Jendel spin pedals to make the C-21x ideal for both sprints and long, flat endurance sessions. The dual water bottle holder helps to keep you fully hydrated throughout your spin sessions.
