Abstract: The combined power supply contains an accumulator battery and a supercapacitor. It contains a universal battery module, made in the form of a metal box which is mounted to the frame of the electric bicycle, and in the middle of which is placed an accumulator battery with a charge protection unit connected to the active battery balancer. A supercapacitor connected to a supercapacitor converter/balancer that is coupled to a current sensor coupled to an overload protection unit of a universal module coupled to a downconverter. The active battery balancer is connected to the battery monitor and controller which is also coupled to the supercapacitor converter battery monitor, temperature sensor, and data exchange module.

Abstract: An invention relates to the field of electronic vehicle control systems, in particular electric bicycles intended for heavy loads. The intelligent electronic bicycle control system includes a controller to control electric motor, a throttle handle, a sensor, a battery, a communication module for transferring data on a movement and condition of electric components and to exchange data with a mobile application and a remote control, an alarm, a light controller to control light, turns and stop signals and audio signal, a controller for collisions prevention and a bicycle computer to display the main parameters of the system, and all elements are connected by a bus. Enhanced functionality.

Abstract: An electric bicycle has an outer double frame, on which a steering plug with a handlebar and a front wheel with a sleeve is mounted in front of a hinge, and a rear wheel with the sleeve is attached behind. A seat is secured to the outer double frame. An internal double frame is built into the outer double frame, each double frame being a spatial construction of profile tubes rigidly connected by interconnected fastening elements with cutouts into which a battery unit is mounted. The fastening elements are triangular in shape, with at least three of these elements being located in front of the outer double frame, and one element attached to the rear side of the outer double frame. Inside the structure is strengthened by vertical elements in the angle form, with the possibility of horizontal movement. The seat is fixed to the outer double frame on a triangular element.
