A system generates haptic feedback in an electric vehicle. The system comprises a frame, an energy storage device, and a wheel rotatably coupled to the frame. A motor receives power from the energy storage device and provides torque to the wheel. A controller determines a first operational state of the electric vehicle and transmits a first torque signal to the motor to control the motor to transmit first torque levels to the wheel to propel the electric vehicle. The controller determines a second operational state of the electric vehicle and transmits a second torque signal to the motor assembly. The motor assembly transmits second torque levels to the wheel to generate haptic feedback. The second torque signal is based on the second operational state of the electric vehicle and a torque profile stored in the memory, where the torque profile defines an irregular-shaped periodic waveform (e.g., a heartbeat rhythm).
