4-Wheel Travel Scooters are economical and easy to transport. Each scooter disassembles easily and fits in most automobile trunks. Four wheels offer greater stability and user confidence. Although primarily designed with outdoor mobility in mind, scooters will work indoors, but may require more turning room for maneuvering through the home. Driving range varies with battery size and user weight, but most can go at least 8 miles on a full charge.
