There have been quite a few good developments in the public transport systems of most Indian cities in the last decade. To list a few:
- JNNURM Low Floor buses deployed through a PPP mode.
- Metro Railway projects initiated in Gujarat, Tamil Nadu, Bangalore, Hyderabad. Existing lines are being supplemented in Kolkata.
- Profusion of Cab Aggregator services like UBER, Ola, TFS etc.
- Introduction of A/C buses in the Metros and Tier -1 cities (Volvo/Tata Marcopolo etc.)
- BRTS Services have been extended to cover the entire stretch of roads in Ahmedabad.
These are welcome developments, and bring a semblance of civility to the use of public transport as a regular commuting medium. However, if we look at the developments closely, we'll find that these services are designed to take a passenger to a nodal point. In many places, the connectivity with the last mile is not facilitated.
Primitivity Personified
Passengers have to, still, rely on overloaded auto rickshaws and other vehicles that do not deserve to carry human lives. The following picture exemplifies this statement.
Where there are no Auto Rickshaws, a human powered vehicle is commonly evidenced. Although they are considered to be environment friendly, cycle rickshaws that ply on our roads have a design that dates back to the 1920s. In fact the term Rickshaw has been derived from the Japanese term jinriksha, which means hand-drawn cart.
A recent study conducted by IISC states approximately
6-8 Billion passenger-km/year in 6 million cycle rickshaws in India- this is a staggering number.
To give you a better picture of how this compares with other forms of transport-the
Indian railways carried 8.4 Billion passengers and the
passenger traffic at airports was only 0.167 billion!
It is surprising that this sector has remained untouched by technological developments for such a long time. Forget about reducing the stress on the rickshaw pullers, companies that manufacture the Rickshaw have not even added a gear shift mechanism till date on their mass produced models. As a result, Rickshaws remain an slow and exploitative means of transportation.
Rickshaws are still used in the first world countries, but in a more efficient and aesthetically appealing avatar...
A few of these were also introduced in Delhi for the commonwealth games in 2010.
Things have changed a lot since the beginning of 2013, when a remarkably basic and functional product began to appear on our roads- the E Rickshaw.
These vehicles have been popular in China for quite some time. There are two versions- the vehicle depicted above is the passenger version. There is another version designed to carry a payload of about 0.4 Tons.
As simple as it gets
Mechanically, there are very few automobiles that are as basic as this one. A look at the specifications will reveal a lot:
Let us look at each element of the vehicle:
The frame is made of steel tubes and sheets welded manually. Fit and finish do not conform to any standards. Paint quality is questionable, but the strength of the sheet is sufficient to prevent a structural collapse.
Most models use a parallel connection of 4 batteries rated at 12 V each. A few models designed for higher payloads (~1000Kg) have 5 batteries to support the higher power requirements.
A 48 V Brushless DC motor is common.
The speed of the motor is controlled through a electronic speed controller (similar to the regulator of your ceiling fan). The device is designed to regulate the current to the motor according to the inputs given by the driver using the throttle switch.
A small differential transfer the power to the rear wheels. The drive train connected to the motor is depicted in the following picture:
Drum brakes are mostly used. An important improvement has been the inclusion of a handbrake.
- Suspension, Wheels and Tires
The vehicle is suspended over leaf springs that are simply too stiff when the vehicle is not loaded. The handlebar is supported by two gas filled shock absorbers.
Wheels look like cheaply made alloys and the tires appear to have been sourced from a toy bicycle. This is one area where a lot of improvement is needed to make this product economically viable in the long run. The tires wear out very fast (
< 10000 km).
You get an instrument cluster containing a speedometer, odometer and a battery level indicator. Some models come with a 'curtain' for rain protection and a flat acrylic sheet that serves as a shield for the driver.
The Silent Revolution
The mechanicals of the vehicle fit into a box that can be easily transported by a logistics company. The entire setup is very simple and low tech.
This is the most important attribute of the product. The simplicity has enabled more than 40 companies in India to manufacture the vehicle in different parts of the country.
Every model is alike because the design has been sourced from the same component suppliers in China. The infrastructure requirements for assembling the product are minimal- a few skilled technicians and basic welding/painting tools will suffice. Many entrepreneurs from rural India have started assembly stations cum dealerships.
The proliferation of entrepreneurs has created employment, but it has also fragmented the distribution chain. The result is reflected in the prices quoted by different manufacturers- it can vary from Rs. 50,000/- to Rs. 120,000/-, depending on the vendor and the state in which you are located.
In the town where I am posted, 3 'factories' have come up in the last 10 months. These are hole in the wall workshops that import the parts from China and then sell the assembled vehicle locally.
They have received an encouraging response- most of the routes supported by Auto Rickshaws have been taken over by the electric vehicles. Owners say that the lower running costs and higher space (compared to the Autorickshaw) are the main factors driving this change. The results are most visible in the congested parts of the area- pollution has significantly reduced.
A major socio-economic change has been facilitated by this industry. Cycle rickshaw pullers, who did not have the wherewithal to invest in their own vehicle, have been extended credit by PSU banks. They do not have to depend on the cartelized rickshaw operators anymore.
The motivation behind this article
The main intention was to catalogue the development of this industry on this forum. Unlike traditional automobile manufacturing, the e-rickshaw assembling business has exemplified two very interesting points:
- Assembly from kits can be done by Small Scale Industries. The distributed production model reduces logistical difficulties and encourages rural entrepreneurship.
- Simplicity is timeless- I am sure that even 10 years down the line, the e-rickshaw will retain the same basics because they do their job well.
It is true that the e-rickshaw needs to be improved - seatbelts should be provided for all passengers, an enclosed passenger compartment needs to be constructed and the dynamics need to be sorted out.
However, even in its present form, the e-rickshaw has emerged as a deserving substitute to the other three wheelers that are serving the country at the moment.
