The CYBEX e-Gazelle S Modular stroller seamlessly integrates smart technology into a baby-gear essential. The high-tech stroller provides electric power on demand, making navigating uphill climbs or cruising downhill feel a whole lot smoother. Control the speed of the stroller with a user-friendly lever built right into the handlebar. Set a gentle rocking motion to soothe your baby, check the battery life, and power on or off as you like using the intuitive user interface. This grow-with-them design easily converts from a single stroller to a double stroller with more than 20 configurations (accessories sold separately).
