Abstract:
A heat sink assembly having excellent heat dissipation for internally integrated inverter hub motor for light electric vehicles and comprising of a thermally conducive ring, the electronic board consisting of multiple inverter switches, a potential secondary electronic board and a heat sink base, where the thermally conductive one piece ring is pressed down on the inverter switches to affix the switches to the hub of the motor thereby creating a mechanism for heat dissipation.

Abstract:
A removable keyless security lock for a light electric vehicle which employs existing permanent magnet brushless motor or motors that is or are programmed to produce high resistance to paddling to prevent theft. This antitheft mode offer resistance to motor rotation, thereby effectively locking the movement of the electric bicycle. An external energy source, such as, a battery is not required to keep the antitheft mode activated. The security lock is easily removable without using any tools and this will not deactivate the antitheft mode.
