Exercise device

Abstract

An exercise device, endlessly pedaled by a user, includes a base unit, a training unit connected to the base unit, a detection unit arranged on the training unit, an analyzing and processing module coupled to the detection unit, and an electrical auxiliary unit coupled to the analyzing and processing module. The electrical auxiliary unit can assist in driving the training unit. The detection unit detects the usage state of the detection unit to generate a detection signal. When a user applies force to the training unit to exercise, the analyzing and processing module will determine that the assistance of external force is required according to the detection signal and transmit an electrical auxiliary signal to the electrical auxiliary unit if the exercise stagnates due to insufficient force. The electrical auxiliary unit assists in driving the training unit to help the user complete exercise according to the electrical auxiliary signal.
