Abstract
An electrically-powered scooter vehicle for use by elderly, disabled and infirm people includes a self-locking connection means for connecting front and rear frame portions of the scooter. The scooter is convertible between three-wheel and four-wheel versions without use of tools. Automatic shut-off circuity minimizes inadvertent loss of battery power due to failure to turn off the scooter. An adjustably lockable telescoping tiller facilitates use of the scooter by persons of all sizes.
