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:
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.
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.
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:
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.
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.
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.
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.
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.
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.

Company Profile
Our company was formerly known as Changsha Double Star Gear
Industrial Co., Ltd, which was established in 1994. It is a
directly affiliated university-run enterprise founded by Central
South University Professor Zeng Tao, the leading expert on spiral
bevel gears in China. It was later renamed as Changsha Senjie Gear
Co., Ltd (abbreviated as "CSG") in 2016. CSG is a production
R&D base specializing in professional design, reserch,
manufacture and sales of high-quality small module spiral bevel
gears and high reduction hypoid gears and cylindrical gears. In
2023, Hunan Dinghan New Material Technology Co., Ltd. was
established as a specialized international export business
department. CSG has strong scientific research and development
capabilities and is also equipped a full set of advanced equipment
including seven-axis five-linkage CNC spiral bevel gear grinding
machines and gear milling machines. By making the best use of the
scientific and technological achievements and equipment of the Gear
Research Institute of Central South University, machanical
processing, heat treatment and testing. We have developed
high-quality products featuring high reduction, high speed, heavy
load, low noise and less teeth for users.
With the quality policy of "scientific and technological
innovation, quality first, being first-class firm and customer‘s
satisfaction", we have won the trust of well-known domestic and
abroad enterprises with stable and excellent quality. It is
committed to be a pioneer of the industry of China's small-module
spiral bevel gears, and is dedicated to providing service for any
related industry requiring industrial robots, CNC turning and
milling compound power tool turrets, industrial sewing machines,
reducers, bicycles, power tools and aeromodelling. We sincerely
look forward to your cooperation!
