Bicycle Gear Set Beveled Cone Gear For Ordinary Three-Speed Bicycle

In an ordinary three-speed bicycle, bevel gears are not commonly used as part of the primary gear system. Instead, these bicycles typically rely on an internally geared hub to provide the three-speed options. However, it's important to note that the specific design and components of bicycles can vary, and there may be variations or customizations that include bevel gears for specific purposes.

If bevel gears are present in an ordinary three-speed bicycle, their role would typically involve one or more of the following functions:

1. Power Transmission: Bevel gears can be used to transmit power from the pedals to the gear system or from the gear system to the rear wheel. They enable the transfer of rotational motion and torque between different components of the bicycle.
2. Direction Change: Bevel gears are capable of changing the direction of motion at different angles. In a bicycle, they can be used to redirect the rotational motion from the pedals to the gear system or from the gear system to the rear wheel, allowing for efficient power transfer.
3. Gear Ratio Adjustment: Bevel gears can be employed to adjust the gear ratios in the bicycle. By changing the sizes or ratios of the bevel gears, the overall gear ratio can be modified, which affects the effort required and the speed achieved when pedaling.

An ordinary three-speed bicycle, also known as an "English three-speed" or "roadster," is a classic type of bicycle that features a specific design and gear system. Here are the key characteristics of an ordinary three-speed bicycle:

1. Frame Design: An ordinary three-speed bicycle typically has a step-through or diamond-shaped frame design. The frame is often made of steel, providing durability and strength.
2. Upright Riding Position: These bicycles are designed for comfortable and upright riding. The handlebars are curved or swept-back, allowing the rider to sit in an upright position, promoting a relaxed and leisurely riding experience.
3. Internal Gear Hub: The three-speed gear system on an ordinary three-speed bicycle is typically housed within an internally geared hub. This hub contains the gears, which are enclosed and protected from dirt, dust, and other external elements. The rider can shift between the three gears by operating a shifter located on the handlebars.
4. Gear Ratios: The gear ratios on an ordinary three-speed bicycle are generally set up to provide a wide range of versatility for various riding conditions. The specific gear ratios can vary depending on the bicycle model and the gear hub used. The low gear is suitable for uphill climbs or situations that require more power, the medium gear is for general riding on flat or rolling terrain, and the high gear is used for high-speed or downhill riding.
5. Full Fenders and Chain Guard: Ordinary three-speed bicycles often feature full-length fenders that cover the wheels, protecting the rider from splashes and debris. They also typically have a chain guard that encloses the chain, keeping it protected and preventing clothing from getting caught.
6. Accessories and Features: These bicycles often come equipped with additional features such as a rear rack for carrying items, a front or rear basket, a kickstand, a bell, and sometimes a built-in dynamo-powered lighting system.

Ordinary three-speed bicycles are often associated with vintage or retro aesthetics and are popular for leisurely rides, commuting, and urban cycling. They offer a comfortable and stylish way to get around, with the convenience of multiple gears for adapting to different terrains.
