Ultimate All-Terrain Performance
The Segway Navimow X450E is engineered for the most demanding British gardens. Its Xero-Turn™ All-Wheel Drive (AWD) system provides outstanding traction and stability. The pioneering front-wheel zero-turn steering effortlessly switches between a true zero-turn and automotive-grade Ackermann steering to prevent turf damage during manoeuvres. Thanks to a perfectly 5:5 balanced centre-of-gravity, dual suspension, and a patented Traction Control System (TCS), it confidently handles slopes up to an 84% (40°) incline, clears vertical obstacles up to 7 cm, and dynamically adjusts wheel torque to prevent slipping on wet or low-traction lawns.
Intelligent Cutting with MowMentum™ Technology
Achieve a perfectly manicured lawn with Segway’s MowMentum™ Technology. The X450E features a wide 430 mm dual-disc deck equipped with 12 sharp blades, powered by dual 180W cutting motors. The cutting height is precisely adjustable between 20 mm and 95 mm. Its adaptive blade system allows the deck to float over uneven ground to minimise scraping, while a smart cutting algorithm automatically detects and lifts the blades when handling challenging, tall, or thick grass. For a pristine finish, the Edgesense™ feature achieves “Zero-Distance Cutting”, mowing within 5 cm of walls and fences.
Wire-Free Navigation & Smart Mapping
The Navimow X450E eliminates the need for a physical boundary wire by using Segway’s advanced EFLS™ NRTK Positioning system. This comes standard with lifetime-free, tri-frequency Network RTK access for an antenna-free setup. This system is enhanced by 360° VSLAM (Visual Simultaneous Localization and Mapping), triple panoramic cameras, and multiple sensors, allowing it to map and navigate the garden with centimetre-level accuracy. The innovative GeoSketch™ Real-Scene Mapping feature generates top-down, real-scene maps, allowing users to visually edit boundaries directly on their smartphone.
AI-Powered Obstacle Avoidance
Safety and intelligence are at the core of the X450E. The AI-Powered 360° VisionFence™ system detects obstacles within a 5-metre range and reroutes in just 0.1 seconds, maintaining a safe distance. With 1.8m Night Vision Sensing, it can reliably detect and avoid animals like hedgehogs and pets, as well as everyday yard objects such as toys, hoses, and garden furniture, day or night.
Smart, Durable, and User-Friendly Design
Designed for complete convenience, the X450E supports up to 120 customisable zones, including no-go areas and individual schedules, all managed via the intuitive Navimow app. It operates quietly at under 68 dB(A) and features an IP66 dustproof and waterproof rating, allowing it to be easily rinsed clean. A built-in rain sensor prompts the mower to return to its dock when weather conditions worsen, and a quad-layer security system ensures it can be located even when powered off. The mower also integrates with smart home systems for voice control and receives seamless over-the-air software updates.

Frequently Asked Questions
Is the NRTK positioning service for the Navimow X4 Series free?
Yes, the Segway Navimow X4 Series includes a lifetime free service for its NRTK (Network Real-Time Kinematic) functionality. This provides centimetre-level positioning accuracy without any ongoing subscription fees, delivering exceptional long-term value.
What kind of garden is the Navimow X450E designed for?
The Navimow X450E is ideal for large and complex lawns up to 5,000m². Its all-wheel-drive system excels on challenging terrain, including steep slopes up to 84% (40°), and it can navigate around obstacles thanks to its 360° VisionFence™ system, making it suitable for gardens that other mowers might struggle with.
Are there any working limitations to be aware of?
The mower has a body width of approximately 61 cm (24 inches), so it needs enough space to pass through narrow gaps. Performance can also be affected in areas with very poor mobile network signal, on inclines steeper than 84%, or when facing obstacles taller than 7 cm.
Does the Navimow X450E require professional installation?
While the Navimow is designed for user-friendly setup, professional installation is highly recommended to ensure the charging station is optimally placed and the virtual boundaries are mapped with maximum accuracy for your specific garden layout. For customers in the Warwickshire area, Sims Garden Machinery offers a free, no-obligation on-site survey to assess your lawn and provide expert advice.
What optional accessories are available for the Navimow X450E?
To enhance its functionality, several accessories are available. These include a dedicated mower garage for weather protection, replaceable blades for routine maintenance, and an electronic gate that allows the mower to travel automatically between different fenced-off areas of your property.
