The Cycle Rickshaw

The humble Cycle Rickshaw or the pedicab is not only the common man's beast of burden, but it also serves to generate considerable employment, especially amongst the underprivileged in the developing countries. It is a relatively inexpensive and all-weather mode of transport- both to own and to operate and is easy to access right ‘at one's doorstep’. Most of all, however, in an age when our cities are beset by the pollution menace of the automobile, it provides perhaps the only viable eco-friendly alternative for the short-haul (say, 3-5 kms). Only in areas where the road surface is highly undulating, does it required motorization. However, gears can be provided for the upclimb and superior braking for downslope. It is getting increasing popular the world over as a clean, healthy, fun vehicle.

The 'Eco-Trike'

Over the last decade, development of the ‘Eco-Trike’ design has involved basic re-engineering of the Cycle Rickshaw, (rather than mere ‘improvement’ of the existing as has been the case with most other recent new designs).

The technology developed utilizes state-of-the-art in bicycle technology such as the use of oversized pipes and advanced welding techniques, uses all-steel structure- disposing older and inappropriate materials such as wood. It engineering-optimizes various design aspects such as layout, transmission, aerodynamics, ergonomics (both for puller and passengers), safety (including stability), utility (user-value) and so on. Redundant parts have been eliminated and the number of parts used minimized, leading to lower maintenance requirements.

Use of monocoque (one-piece integrated) structure a la racing cars/aircraft leads to minimal vehicle dead-weight. The use of sturdy Moped type fork design (not shown in photos) eliminates the problems associated with frequent fork failure in conventional rickshaws.

Space occupied on the road is considerably less due to slick designing- a boon for our overcrowded towns. For exports, a detachable canopy has been fabricated as a result of which as many more ‘Eco-Trikes’ can be accomodated in a say, 20’ container. Also a small turning circle, ease of parking on its back, shorter and more efficient chain drive (which does not come off any longer while running) amongst other benefits.

Use of coiled springs above the bearing mounts (in conventional clips with ball bearings or in plummer blocks with self-aligning bearings) reduces vibration and shock. A shocker type front-fork is also possible.

Smaller wheels (with the overall drive ratio being adjusted by change in the freewheel size) with 24” ‘balloon’ tyre in the front and 20” dia. or heavy-duty 21” dia. moped tyres in the rear reduce the centre of gravity height, thereby reducing the vehicle tendency to topple off- the no.1 defect of the conventional rickshaw. Also, the passengers- especially the elderly and the children, can now enter and exit from the vehicle with ease due to the low floor height.

Introduction of a simple rear-axle Oil-hydraulic Disk-brakes (recently developed by us) improves braking efficiency. Disk- brakes can also be provided individually on the rear wheels or on all the 3 wheels. For the front brake, choices range from simple but effective Philip type brakes to Cantilever brakes to Oil-hydraulic Disk-brakes. Band type Drum brakes are also possible in the rear. Reflectors for night safety can be included.

The passenger seat has been developed in an optional ‘folding’ mode, thereby combining the passenger and work (load carrier or ‘thela’) rickshaws in one so as to enable the puller to earn more flexibly. Seats use webbing and are ergonomic and comfortable, although other possibilities also exist. The puller seat and handlebar is designed for adjustment for variation in puller physique.

The canopy has a fixed structure (so that passengers and goods remain protected at all times), which is aerodynamic. The waterproof covering cloth has velcro for ease of affixing and removal, if required. Rain-covers on three sides are provided.

Finally, the vehicle scores very high on aesthetics- cities will wear a new look with ‘Eco-Trike’.

Gears can be accomodated with ease to reduce effort while starting-up the vehicle or climbing slopes. 3-speed gears are standard, but upto 18-speed gears can be provided.

Application-based Models

A variety of other end-user applications have been developed for future production, such as for:

  • School-children/joy-ride
  • Garbage-collection
  • Delivery/"Shop-on-wheels"
  • Ice-cream vending
  • Vegetables/fruits vending
  • Pick-up
  • Other tailor-made designs for specific applications

Several prototypes using 50-100 cc auto-gear petrol power-packs have also been developed along with the suitable transmission, suspension, braking etc. A powered ‘fourth wheel’ can be attached at the rear optionally. Use an Electric battery power-pack is being envisaged. We also design 100 cc, 4-stroke Motor-cycle driven driven Rickshaws with petrol or gas fuel options.
