Bring the experience of real road cycling into your home with the Horizon GR4. Designed for a more immersive and motivating ride, the GR4 offers smooth resistance, a realistic cycling feel, and smart features to keep your workouts effective and engaging—whether you're a beginner or building on your indoor cycling routine. 

Real Road Feel at Home 

The GR4 is engineered to mimic the feel of outdoor riding, giving you a smooth, consistent pedal stroke and a natural riding position. It’s ideal for users who want to train seriously or just enjoy a more authentic cycling experience indoors. 

Smooth, Precise Resistance 

A micro-adjustable tension knob lets you fine-tune resistance on the fly—perfect for switching between sprints and climbs during your workout. This level of control makes it easy to follow along with studio classes or create your own high-intensity intervals. 

Smart Handlebar Design 

Three-position handlebars give you flexibility to switch up your grip, while the built-in heart rate sensors help you stay in your target zone. Monitor your effort in real time to get the most out of every session. 

Optional Console with Glow Ride 

Upgrade with the optional LCD console for real-time stats, workout programs, and the unique Glow Ride lighting system—designed to guide your ride through three different phases: warm-up, steady-state, and high-intensity intervals. It’s a simple way to stay motivated and on track.
