== Introduction ==
  −
Isolation is one of the key elements of [[poverty]]; isolated communities have little or no access
  −
to goods and services, and few opportunities to travel beyond their immediate surroundings.
  −
This restricts agricultural productivity, reduces health and educational and limits
  −
opportunities for employment and political opportunity.

  −
Limited financial resources prevents investment in transport maintaining the position of
  −
poverty and isolation. Consequently,
  −
there is a need to develop alternative,
  −
more affordable means of transport
  −
 
  −
Developing such systems requires
  −
consideration of four key elements:<br>
  −
• the improvement of village level
  −
infrastructure such as paths,
  −
tracks, and footbridges<br>
  −
• the provision of adequate and
  −
affordable rural transport services<br>
  −
• the siting of services closer to the
  −
communities , thereby removing or
  −
reducing the need for lengthy travel<br>
  −
• the promotion and use of
  −
intermediate means of transport
  −
including; pack animals, sledges,
  −
animal carts, cycle based transport
  −
and some low cost motorised
  −
devices. One of the more common
  −
types of intermediate transport is
  −
the bicycle.<br clear="all">

== Bicycles ==
  −
Bicycles are a low cost means of transport that can improve access to water, health facilities
  −
and, for example, address stove marketing problems faced by woman producer groups in
  −
Kenya.
  −
 
  −
The bicycle is still expensive for poorer families in Africa and can cost between 20 to over
  −
100 per cent of a rural household’s annual income. Therefore, transport needs to be
  −
supported by an affordable system of manufacture, supply, and repair.
  −
 
  −
Affordability is related to the availability of spare parts and repair services, which are
  −
sometime lacking in rural areas. Several projects have attempted to boost local economics
  −
by encouraging artisanal production of suitable transport and improve the local capabilities of
  −
metal workers to maintain and repair bicycles and other types of transport.
