Product Description

The Sterling S425 is a high-performance 8 mph mobility scooter designed for users who demand more – more power, more comfort, and more range. Whether you're commuting along the pavement or heading onto the road, this class 3 scooter delivers a smooth, reliable ride with premium features throughout.

Built with a 55Ah battery, the S425 offers an impressive range of up to 26 miles, while pneumatic 30cm wheels and adjustable all-round suspension ensure excellent stability and comfort across various terrains. The robust frame can support users up to 23.6 stone, making it ideal for daily travel or weekend adventures.

Key comfort and convenience features include a swivel captain’s seat, ergonomic delta tiller, and intuitive wig-wag controls, giving you complete control at your fingertips. With LED headlights and rear lights for enhanced visibility and a large front basket for shopping or personal items, the S425 is as practical as it is powerful.

Its carbon-metallic finish adds a modern edge, while optional upgrades like a heavy-duty rear suspension kit allow you to customise the ride to your preference.
