Our Take
The Sterling S425 from Sunrise Medical is a robust, well-appointed class 3 road-legal scooter. Full lights, indicators and a horn make it road-safe. Its four-wheel base keeps it stable on roads and pavements. So it suits riders who want a dependable road scooter.
It reaches the class 3 limit of 8 mph on the road. A single charge also covers around 26 miles, enough for a full day out. It carries riders up to 150 kg, so larger users get solid support. A comfortable seat keeps longer trips relaxed.
The main things to plan for are size and weight. At 117 kg the Sterling S425 cannot be lifted whole. Sunrise give a 35 kg heaviest removable part — the seat, on its sister models — but the machine still needs a ramp and proper storage rather than a car boot. For a similar rugged road model, also compare the TGA Breeze S4. It is worth a test drive before you choose.
Serious mileage is the point of the Sunrise Medical/Sterling Sterling S425, and it shares that ground with a few other road-legal machines. The Drive Medical Viper sits in much the same bracket and the Electric Mobility/Rascal Vecta Sport is very similar on paper, while the Electric Mobility/Rascal Ventura is lighter at 110kg. A test drive of whichever appeals will tell you the rest.
The Sunrise Medical/Sterling Sterling S425 is one for the miles, pairing distance with a road-going ride. Before you decide, a hands-on try will tell you what really suits you.
