[0002] In modern society, bicycles are not only an important means of transportation but also a popular leisure activity and fitness method. They are widely used in transportation, entertainment, and sports. A bicycle is a small land vehicle propelled by human pedaling, typically consisting of two wheels, although three-wheeled or single-wheeled variations also exist. The rear wheel is driven by a chain drive connected to the pedals, while the front wheel is used for steering. Shock absorbers are a crucial component of bicycles, effectively absorbing road impacts and improving riding comfort and stability. Shock absorbers include spring shock absorbers, air shock absorbers, urethane shock absorbers, and hydraulic shock absorbers, each with its own advantages and disadvantages. However, current bicycles generally only allow for the installation of one type of shock absorber, making it impossible to adjust and replace them according to rider weight and different riding conditions. This results in less than ideal shock absorption and cushioning, failing to meet adequate shock absorption requirements and negatively impacting the actual riding experience. Utility Model Content

[0014] The present invention will now be described in detail with reference to the accompanying drawings.
[0015] like Figures 1 to 2As shown, this utility model discloses an electric bicycle with easily adjustable shock absorbers, including a frame 1 and a shock absorber 2 detachably mounted on the frame 1. The frame 1 includes a head tube 11, a tail tube 12 spaced apart from the head tube 11, and a body tube 13 disposed between the head tube 11 and the tail tube 12. The head tube 11, body tube 13, and tail tube 12 are integrally formed. The tail tube 12 is provided with an extension seat 14, which extends away from the tail tube 12. The extension seat 14 is provided with a rear fork 3, one end of which is connected to the shock absorber 2, and the other end of which is provided with a rear tire 15.
[0016] The front tube 11, body tube 13, and rear tube 12 are integrally formed to form the frame 1. Because the frame 1 is integrally formed, it has good structural stability and requires minimal assembly steps, making manufacturing highly efficient. An extension seat 14 protrudes from the outer surface of the rear tube 12. The extension seat 14 is equipped with a rear fork 3, one end of which is connected to the shock absorber 2, and the other end of which is fitted with the rear tire 15. The shock absorber 2 counteracts the impact force experienced by the rear tire 15 during road travel. Existing shock absorber types include spring shock absorbers 2, air shock absorbers 2, hydraulic shock absorbers 2, damping rubber shock absorbers 2, hardtail shock absorbers 2, and full shock absorber systems, each with its own advantages and disadvantages. For example, spring shock absorbers... Spring shock absorbers (2) are the most common type, made of steel wires of different specifications in a spiral shape. They compress under stress, absorb road impacts, and return to their original shape. Their advantages include long lifespan, low failure rate, and ease of maintenance, but their disadvantage is their heavier weight. Air-pressure shock absorbers (2) use gas pressure for cushioning, are lightweight, portable, and adjustable, suitable for different riding needs. Hydraulic shock absorbers (2) operate through hydraulic cylinders, are easy to maintain but have higher repair costs. Rubber-resistant shock absorbers (2) are easy to adjust and maintain, but suffer from hardening due to aging and are now less commonly used. Hardtail shock absorbers (2) are a simple form of front suspension, with a simple and lightweight structure, suitable for urban roads and flat surfaces. A full suspension system includes front and rear shock absorbers, suitable for complex terrains such as mountain bikes and off-road bikes. Therefore, shock absorbers (2) can be detachably mounted on the frame (1), allowing riders to easily install or replace the appropriate type of shock absorber (2) according to their actual needs, offering strong compatibility. This invention enables the installation and removal of the shock absorber 2 on the frame 1, allowing for targeted replacement of the shock absorber 2 according to the rider's weight and different riding conditions, resulting in good shock absorption and improved riding experience.
