Abstract: Disclosed is a training system for providing fitness training to a user riding an e-bike. The training system includes a motor system attached to a rear wheel of the e-bike and a detachable training stand for raising the rear wheel from the ground to allow the user to ride in various terrain modes from a stationary position. The motor system includes a stator assembly, a rotor assembly, an axle, a memory unit configured in the stator assembly to store set of instructions and plurality of terrain modes for riding the e-bike, and a bi-directional communication unit attached to the stator assembly for receiving terrain modes and other commands over the communication network.

Abstract: Disclosed is a liquid filled electric motor to eliminate over-heating of direct drive motors and for preventing leakage of liquid from inside to the outside environment. The liquid filled electric motor is attached to the frame of a vehicle. The liquid filled electric motor includes a stationary axle attached to the frame of the vehicle, an angled hole configured on the stationary axle, a rotor for rotating around the stationary axle; a stator attached directly to the stationary axle, and one or more cables to energize the stator. The cables exit at an angle through the angled hole in the stationary axle to prevent capillary action for preventing leakage from inside to the outside environment. The level of the liquid is less than the full volume of the empty space in the electric motor.
