Abstract
Provided is a fitness bike. The fitness bike includes a frame, a toggle member and a drive assembly. One end of the toggle member is movably connected to a handlebar of the frame, and the toggle member is capable of being toggled by a hand gripping on the handlebar. The drive assembly is disposed on a body of the frame and includes a load motor, a transmission mechanism and pedals, where a motor shaft of the load motor is drivingly connected to the pedals via the transmission mechanism. In the fitness bike, the load motor is used for providing resistance to simulate resistance received in a riding process, thereby eliminating a traditional flywheel structure, improving safety, lightening a weight and reducing a volume.
