Abstract

A frame with a novel tubular rear fork comprises a rear fork component, the rear fork component further comprises a tubular rear fork for fixing a rear axle, a positioning washer and a fastening nut, the tubular rear fork is in the shape of a bottomed tube, and the side and bottom of the tubular rear fork are provided with a through opening for mounting the rear axle. After assembly, the rear axle enters the tubular rear fork via the through opening, the positioning washer is fitted in the rear axle through the shaft end, the inner diameter of the positioning washer meets the rear axle, and the outer edge of the positioning washer fits a tubular inner wall so that the rear axle is positioned safely and reliably in the radial direction of the rear axle. The fastening nut fits the rear axle through a screw, a rear wheel is axially fixed by compressing the positioning washer, and the rear wheel is radially fixed in non-friction manner through the fitting of the fastening nut with the positioning washer. The frame can provide improved safety and reliability of the rear wheel of a two-wheeled vehicle during driving.

Description

technical field [0001] The invention belongs to the field of electric bicycles or parts of bicycles, and in particular relates to a novel cylindrical rear hook and an electric bicycle including the hook. Background technique [0002] At present, with the increasing awareness of people's health and green life and the continuous maturity and innovation of bicycle technology, electric bicycles and bicycles have become the simplest, most practical and most widely used means of transportation in the world. While the performance of electric bicycles and bicycles has been greatly improved, electric bicycles and bicycles have gradually formed a culture and are recognized by more people. [0003] Existing hooks are generally sheet-type hooks, and the sheet-type hooks are provided with an opening for placing the motor shaft and fixing it with screws. However, during the entire use of the bicycle, after the screws are loosened, the motor shaft is likely to fall off from the opening, w...
