Abstract
Description
Technical Field
[0001] This utility model relates to an independently adjustable device for a pedal arm, and more particularly to an independently adjustable device for a pedal arm that can be directly installed on the pedal arm and rear brake adjustment seat of a bicycle. By adjusting the device of this utility model, the height of the pedal arm can be quickly and conveniently adjusted to accommodate different riders, making the overall pedal arm more practical and convenient. Background Technology
[0002] The position of the pedal arm on a bicycle is crucial for riders, as it affects the smoothness of shifting gears and braking. Traditional bicycle pedal arm positions are set based on the average person's height, build, and leg length. However, every rider's height, body type, and leg length are different, and the traditional pedal arm position cannot accommodate all riders' body shapes. For riders whose body shape is not average, the pedal arm position can lead to an unpleasant riding experience. This can easily cause muscle soreness in the shin and ankle, and may even affect the rider's pedal response due to an unsuitable pedal arm position, potentially leading to dangerous situations while riding.
[0003] Furthermore, in traditional bicycle structures, adjusting the angle of the pedal arm is equivalent to fine-tuning the shifting torque. The original design of the pedal arm is an assembly of two or more components without an independent adjustment mechanism. If you want to adjust the angle of the pedal arm separately, it will affect the feel when shifting gears, so you cannot achieve a good adjustment result.
[0004] Therefore, the purpose of this utility model is to actively disclose how to create an independently adjustable pedal arm that can be installed separately on the existing structure of a traditional vehicle. With simple adjustments, the pedal arm angle can be adjusted to suit the different riders' body shapes, making riding smoother and improving safety and convenience. Utility Model Content
