Description

Technical Field

[0001] The utility model belongs to the technical field of electric power-assisted bicycle accessories, and in particular relates to a multi-purpose bracket for an electric power-assisted bicycle. Background Art

[0002] The control instrument of an electric-assisted bicycle can display riding data such as power, gear, speed, single mileage, light display, pedaling frequency, riding time, instantaneous power, calorie consumption, etc. in real time. It is the main structure of human-computer interaction in an electric-assisted bicycle. In order to facilitate the rider to view and operate, it is very important to firmly install the control instrument on the handlebar during riding. The existing control instrument is generally installed on the handlebar through a fixed bracket. The dial viewing angle of the control instrument is fixed relative to the rider and cannot be adaptively adjusted according to the rider's body shape and usage habits. During riding, in order to ensure riding safety, most riders can only take a quick look at the instrument during rapid speed to obtain real-time data. If the installation of the instrument does not conform to the riding habits, or the dial cannot match the rider's best visual angle, the data cannot be seen at a glance, which may cause the bike to fall off in a matter of seconds, posing a great safety hazard.
