Used Small Boot Scooters
Boot scooters are small class 2 mobility scooters, specifically designed to come apart to be transported in a car boot.
They can also be split apart for easy storage.
Boot scooters are pavement and shopping centre use only, although some people have success using them in parks where there is a decent path that is not muddy or covered in gravel.
Buying a used boot scooter, you can save substantial amounts over new, ofter around 50%.
