Some bicycles do not run

There are a variety of ways in which man can power. Typically there is an internal combustion engine. It is an engine that enters a car. The engine system is not environmentally friendly because it consumes oil and emits soot. In developing countries, it is also difficult for the general public to easily design, manufacture and produce. This means that it is not suitable for proper technology.

Electric motors are also frequently used power. The battery can be connected and the motor rotated to perform various tasks. It does not emit soot as there is no combustion work like internal combustion engine. There is less concern about destroying the environment. However, the cost of making multiple motors that can be used by humans can be daunting. The cost of buying a motor can be a burden for the poor.

​

If so, aren't there eco-friendly yet inexpensive power sources? Even now, bicycles on the road can be the answer. A person turns the pedal directly with his feet to produce power. This force is transmitted to the wheels and the bike runs. Human power is converted into kinetic energy and used as a means of transportation.

Bicycles do not harm the environment. It is eco-friendly because it runs by human power. This is why many countries recommend bicycles. Does not emit carbon dioxide Bicycle prices vary widely. But if you don't use expensive parts such as carbon frames and drivetrains, you can make bikes at a low price.

​

The focus on bicycles isn't just because they're cheap and eco-friendly. This is because a small modification of the method of turning a wheel by pedaling a bicycle can be used as a power for various purposes. It was Dr. Job S. Ebeneze who paid attention to the rotational energy of bicycles with proper technology.

He created a 'dual purpose bicycle' through a company called 'Technology for the poor'. To use the bicycle not only for transportation but also for other purposes. Dr. Ebenezer connected the bicycle to a chain changer (attachment) and added a stand to create a machine that gains rotational power by human force.

​

Dr. Ebenezer gave several considerations for designing dual-purpose bicycles. When most of these considerations are followed, titration techniques can shine. Considerations are as follows:

​

This device must be suitable for local manufacturing capabilities.

△ Attachment parts (attachment) should not be expensive even when using cheap materials.

Low-income people must be easily accessible and meet the basic needs for mechanical power.

• Manufacturing, operation, maintenance and repair should be simple.

It should be able to be used for as many different purposes as possible, and to be able to transfer power to a variety of farm equipment and small machines used in agriculture.

Use materials and techniques available locally. Standard steels such as steel sheets, iron (pipes, etc.), angle irons, and flat stocks sold locally must be used. In production at the factory, the tools must be suitable for the production of components for dual purpose bicycles.

△ Use standard bicycle parts whenever possible.

△ It should be easily applicable to as many bicycles as possible. Bicycles should not be permanently modified in any form.

△ It should be easy to attach and detach the bicycle. Do not interfere with the use of bicycles for transportation.

The stand to provide stability in power production must be able to be turned upside down. The stand and carrier are parts that permanently attach to dual purpose bikes.

△ Power generating device must be efficient. A relatively high RPM (near 200) must be implemented for application diversity.

△ Make sure the power generating device is attached to the front side sufficiently to prevent pedaling.

Changing drive ratios should be simple so that the power plant can power a variety of machines. We find that the V-belt and pulley arrangement is the best fit.

The device must include a ratchet mechanism to allow the operator to periodically rest and save energy.

Because durability is of the utmost importance, avoid overweight the device.

​

As the design considerations show, many elements were included to meet the right technology. For example, it is suitable for local manufacturing capacity, low-income people access, inexpensive materials and ease of operation and maintenance.

​

To make a dual purpose bike, you first need a bike. Dr. Ebeneze recommends a standard bike. Inexpensive bicycles without gears. Bicycles, which were formerly known as 'rice house bikes', are standard bikes.

​

Attach the pedal power attachment to the bike. It is best to install it in front of the pedals so that they do not interfere with the pedals. Dr. Ebeneze also made reference drawings to make the device easier. Normally, when driving a bicycle, it is used as it is, but when power is needed, a belt or the like can be connected to a power transmission device.

A stand is absolutely necessary. This is because a dual purpose bicycle must be fixed stably so that even workers can safely supply power. The key point of the stand is that it can be used as a carrier to load up when not fixed. There is also a design to make this stand and carrier.

Dual purpose bicycles are versatile. It can be used in conjunction with a tool to grind or thresh grains. The basic power of the pump to transfer water can also be made into a dual purpose bike. Dual-purpose bicycles shine especially when used in agriculture. Turn the pedal to rotate the round panel and connect the pipe to it. Combined with millstone, the grains can be peeled or ground into powder. Dual-purpose bicycles are popular in India.
