Summary:

One of Our Most Popular Road Scooters

Faster, stronger, and longer – the Sterling S425 crams in all the features of its little brother the S400, but with added power! Taking the bright, front/rear LED lights, all-round suspension and combining it with a maximum speed of 8mph*, the S425 is fully legal for road use as well as on pavements.

Perfectly Capable

As you will 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!

High Range

Travelling at speeds of up to 8mph* and a max range of 26-miles* on a full charge, this gives you around 3.5 hours travel time at full speed, you will not have any issues getting to where you want, when you want. With its deep front basket you will be able to do your shopping and have space to store your essentials.

*Speed and range may vary depending upon user weight, type and incline of terrain, weather, battery charge and condition, operating speed and general driving situation.

Simply complete the declaration form at the time of purchase, and you can enjoy significant savings on the mobility solutions you need.

Delivery Options

Free Delivery

Boxed by courier - 2 working days - if you need more help on delivery such as bringing the product inside the house or unpacking/assembling please consider the white glove delivery option.

White Glove Delivery: full pre-delivery inspection, demonstration on delivery & packaging removed from £79:

We recommend this option for any scooter faster than 6 mph as these can arrive partially dismantled to make them easier to ship in boxes. Please contact us if unsure.

Returning/Exchanging an unwanted order after despatch

  • You have the right to return your order within 14 calendar days of receiving the goods. After this period we cannot accept any returns.

  • We will not refund you any supplementary costs arising if you chose a type of delivery other than free delivery.
  • If the product(s) are not returned in their original condition, we reserve the right to charge for repair or replacement of any product(s).
  • Unfortunately we cannot accept returns on product(s) that are built to order, have been adapted to suit your requirements, or for products that can void Health & Safety regulations if used e.g. incontinence, bathroom or toilet products. A refund can only be given if the product(s) arrives faulty, damaged or incorrect.
  • Your refund will be processed back to the payment method used to place the order. Refunds can take 5 - 10 working days to be processed.

This means you will be refunded the lowest price delivery option available to you at time of purchase for most items we sell this is the free delivery option, for smaller orders this refund will be the royal mail delivery charge. In compliance with CCR, upgraded postage options such as 'pallet' service and white glove delivery are non-refundable.

What warranty does the scooter with?

1. What’s covered

For 12 months from when you bought it, we’ll fix or replace anything that breaks because it was made wrong—not because it wore out, was damaged, or wasn’t looked after.

2. Free home callouts

If something covered by the warranty goes wrong while your
scooter is in Mainland England, Scotland, or Wales, we’ll send an
engineer to your home for free—except for batteries (see next section).

3. Batteries – how their warranty works

Batteries have a return-to-base warranty only.

That means:

  • If you think your batteries are faulty, you send them to our head office.
  • We’ll test them in our workshop.
  • If they fail because of a manufacturing fault, we’ll send you
    replacements for free.
  • If the problem is because they weren’t charged or maintained correctly, we
    will:
  1. Call you to explain what we found.
  2. Give you tips on how to fix or improve the batteries (if possible).
  3. If the batteries can’t be recovered, we’ll give you a price for new ones
    and send them once payment is received.

4. What’s not covered by free callouts

Some problems are normal wear and tear or accidental damage,
so they aren’t covered by free visits. These include:

  • Things that wear out: bulbs, fuses, tyres, inner tubes, brake pads
  • Punctures
  • Batteries (see section 3)
  • Damage from accidents, misuse, neglect, or unauthorised repairs
  • Routine servicing or adjustments

We can still come out for these, but we’ll charge our standard callout and repair rates.

5. London visits

If you’re in Greater London, any home visit has a £40 surcharge, even for warranty repairs. This covers parking,
congestion/emission charges, and the extra travel time London traffic causes.
