The invention relates to a
motorized bicycle with an inertial
energy storage mechanical device of a
flywheel set, which mainly comprises a tubular support beam, a
back support plate, a front support plate, a main shaft, auxiliary shafts, flywheels, bearings, a tubular wind shield cover, a front end face cover, a back end face cover, auxiliary friction wheels, a main friction wheel, a chain wheel, a
bevel gear, a
clutch, a front wheel and a back wheel, wherein the inner
diameter of the tubular support beam is fixedly connected with the outer diameters of the front end face cover and the back end face cover, the main shaft is fixed in the center holes of the front end face cover and the back end face cover through the bearing, the middle of the main shaft is connected with center holes of the
back support plate and the front support plate, the back part of the main shaft is connected with the
clutch, the auxiliary shafts are respectively fixed holes formed on the
back support plate and the front support plate at equal angle intervals through the bearings, the middle of each auxiliary shaft is connected with the center hole of one
flywheel, the outer diameters of the back support plate and the front support plate are connected with the inner
diameter of the tubular wind shield cover, the outer
diameter of the front end shaft of each auxiliary shaft is connected with the center hole of one auxiliary friction wheel, the auxiliary friction wheels are in contact with the main friction wheel, the main friction wheel is longitudinally fixed at the inner side of the front support plate, the back part of the tubular support beam is connected with the back wheel, the front part of the tubular support beam is connected with the front wheel, and the middle of the outer diameter of the tubular support beam is connected with the chain wheel. The invention can be used for short-distance journey of people.
