The compact, 8 mph road-ready mobility scooter.

Faster, stronger and longer – the S425 crams in all of the features of its little brother, but with added power! Taking the bright, front/rear LED lights, all-round suspension and combining it with a maximum speed of 12kph (8mph), the S425 is fully legal for road use as well as on pavements. As you’ll be travelling on roads, the increased wheel height (30 cm) will help to tackle those usual outdoor obstacles with ease. Fancy venturing a little further? The larger battery size of 50Ah 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!

Frequently Asked Questions

No. Although they may look the same, a car battery and a traction battery are designed and built completely differently. If car batteries are used they will fail.

This can happen if the weather is very cold and damp. The reason for this is that ALL batteries perform less efficiently under these conditions, that is why it is very important to keep batteries fully charged.

This depends on how much you pay per unit for your electricity. The unit cost is usually found on your electricity bill. As an average, your battery charger uses approximately 438 units of electricity per year. The annual cost is 438 times the cost per unit. For the daily cost, simply divide the answer by 365.

Charge your scooter every day whether you use it or not. It is quite safe to leave your vehicle constantly on charge for up to five days. Charge periods should last for at least 8-10 hours for normal use and 10-15 hours for heavy use. Please refer to your owners manual for charging information.

There are a few things you need to do when storing your vehicle for extended periods without use. Before storing, charge the batteries for 24 hours or more. When ready to store, disconnect the battery box or battery leads from the vehicle. If possible and it is safe to do so, release the parking brake (freewheel). Keep the vehicle as dry and warm as possible. Return to vehicle at least once a month to re-connect batteries and charge for 24 hours or longer. If you have an off-board charger it would be easier to remove the batteries from the vehicle and store them in a dry, well ventilated place where they can be charged every month.
