Abstract
A motor scooter embodying an improved electric motor driven wheel. The electric motor for driving the wheel is quite compact and is designed so as to be nested within the disk of the wheel. The motor controller is mounted adjacent the wheel in a protected area but is cooled by airflow across it and by heat transfer to the motor housing. Oil in the motor assembly also will cool the controller. A two speed planetary gear transmission is employed that also is compact and can be nested easily within portions of the electric motor. In addition, an improved brake assembly is also mounted integrally within the motor driving mechanism.
