The compact, 8mph road-ready mobility scooter.

Faster, stronger and longer.

As you’ll be travelling on roads, the increased wheel height (30cm) will help to tackle those usual outdoor obstacles with ease. Fancy venturing a little further? The larger battery size of 55Ah will help to power your way. Plus with the S425’s unique carbon-metallic colour, heads will turn just as easily as your S425 does!

Features & Benefits

All-Round Suspension

With the S425’s larger 30cm pneumatic wheels and all-around adjustable suspension system, you’re always ensured of a comfortable ride when navigating over bumpy terrain or tackling those tricky drop-kerbs. Plus with the optional heavy duty rear-suspension kit for the S425 mobility scooter, you’re also able to achieve an even firmer and stiffer ride!

Powerful LED’s to light your way.

With advanced LED lighting technology, the lights on the S425 mobility scooter are 400 times more energy efficient than standard bulbs, so not only are you using less battery power on every trip, you also won’t have to worry about changing bulbs either. Powerful and approved for road-use, it won’t just be the S425’s style that attracts attention.

Comfort on every trip.

Finding your perfect seating position is a breeze with the easy-to-adjust luxury seating. Adjust the seat height, depth and recline to suit your own unique driving position. The flip-up comfort armrests are also width, angle and depth adjustable – and combined with the seat rotation ensures that transferring in and out of your mobility scooter is effortless.

Intuitive controls

Seeing as youll be spending a lot of time behind the controls of your S425, weve ensured the delta handle-bar is ergonomic and easily within reach thanks to the infinitely adjustable tiller (the clever design even ensures that the headlight is automatically tilted as the tiller is adjusted). The unique wig-wag control system also allows you to control your mobility scooter by using your fingers or thumb.
