Abstract: The disclosure provides an assist wheel including a wheel, a handrim, an elastic component, two contact components, a driving assembly, two film sensors. The wheel is configured to be rotatably disposed on a wheelchair frame. The handrim is disposed on the wheel and rotatable with respect to the wheel. Two opposite ends of the elastic component are respectively connected to the wheel and the handrim. The two contact components are respectively disposed on the wheel and the handrim. The driving assembly is configured to be fixed to the wheelchair frame. The two film sensors are disposed on the driving assembly and respectively pressed by the two film sensors. Each of the two film sensors is configured to generate a sensor value. The controller is configured to receive the sensor values from the two film sensors and signal the driving assembly.
