Title: LIGHT FOLDABLE ELECTRIC BICYCLE
Abstract:
A light foldable electric bicycle, mainly comprising handlebars (1), a front bicycle frame (2), a rear bicycle frame (3), a seat frame (4), pedals (5), a front wheel (7) and a rear wheel (9). The rear bicycle frame (3) is designed to be two parts, i.e. a left bicycle frame (17) and a right bicycle frame (18). A bicycle frame unfolding locking groove (15) is provided above the left bicycle frame (17) and the right bicycle frame (18). Correspondingly, a bicycle frame locking shaft (12) is mounted and provided on the seat frame (4). When the bicycle frame is unfolded, the bicycle frame locking shaft (12) is fixedly locked onto the bicycle frame unfolding locking groove (15), and then the front bicycle frame (2), the seat frame (4) and the rear frame (3) form a triangular configuration, such that the bicycle frame, after being unfolded, is stable and secure. When the bicycle is being folded, the bicycle frame locking shaft (12) is disengaged from the bicycle frame unfolding locking groove (15), and then the front bicycle frame (2), the seat frame (4) and the rear frame (3) can be quickly folded and superposed together between the left bicycle frame (17) and the right bicycle frame (18). The folded bicycle as a whole is compact, small in size, and easy to carry or drag.
