  • Electrically-powered scooter for personal transport

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.
