Detailed description
The Sterling S425 is built as a practical, road-ready mobility scooter that balances comfort with everyday capability. With its 8 mph top speed and bright front and rear LED lights, it’s intended for confident outdoor use on both pavements and roads. The lighting uses efficient LED technology so you don’t need to worry about frequent bulb changes, and the lights give good visibility in lower light conditions.
Ride quality is a clear focus, thanks to all-round suspension, pneumatic tyres and a raised wheel height of 30 cm (12 in). Those larger wheels improve clearance over typical obstacles such as dropped kerbs and uneven paving, helping the scooter glide more smoothly over outdoor surfaces. A spacious footwell also helps you find a comfortable leg position for longer trips.
Comfort and transfers are made straightforward by the multi-adjustable luxury seat, which adjusts for height, depth and recline and rotates to aid getting on and off. The flip-up armrests are adjustable for width, angle and depth so you can tailor the position for safe, comfortable transfers. Seat height adjusts between 45 and 50 cm to suit a range of users.
Controls are simple and flexible. An ergonomic delta handlebar with the wig-wag control lets you drive using either thumbs or fingers, and an infinitely adjustable tiller helps you find the right reach and posture. The headlight tilts automatically with the tiller so the beam stays aligned as you change the handle angle. Manoeuvrability is helped by a tight turning radius for its class.
Underneath, the scooter is built to carry a substantial load while remaining stable. It supports a maximum user weight of 150 kg and has a robust overall weight of 117 kg. The scooter can manage modest slopes when used within its safe limits and is intended for everyday outdoor journeys.
