Detailed product description
The Monarch Onyx Mobility Scooter takes a comfort-led approach while staying practical for everyday travel. The plush heated Captain seat gives a warm, comfortable place to sit, and the superior suspension smooths out uneven surfaces, so rides feel steadier and less tiring. The scooter’s styling and finish lean towards the premium end, available in either Bentley Blue or Racing Green.
Performance is tuned for real-world use. A 450 W motor delivers enough power for a 12° climb capability and a controlled top speed of 8 mph, while the twin 2 x 55AH batteries provide a range of up to 31 miles between charges. With 10-inch wheels front and rear and 6 cm ground clearance, the Onyx handles a variety of surfaces with confidence.
Practical features are built in to support daily life and safety. You get integrated Bluetooth GPS navigation for route guidance, heated handlebars for comfort in colder weather and a rear lockable storage box for bags or shopping. Safety items include auto turn indicators and a factory-fitted alarm to help protect the scooter when parked.
The Onyx is designed with user capacity and stability in mind. It supports users up to 24 stone and is a relatively sturdy unit, weighing 92 kg excluding the batteries. Its overall footprint and practical storage mean it suits both longer trips and everyday errands while retaining the comforts expected from a premium model.
