Cardboard bicycle

A bicycle made from a 100% recycled materials (predominantly consisting of cardboard) has been invented by a man named Izhar Gafni. What’s mindboggling is that this cardboard bicycle can be made for just $9. The links provided below expand on it:

This is a wonderful piece of technology that has great potential in developing and underdeveloped nations. Imagine the impact a cheap, maintenance-free vehicle could have on such countries. 

Possible innovation: 

a)   Couple the cardboard bicycle with a cardboard cart and this could greatly increase the productivity of a rural worker/farmer. He/she could traverse distances unimaginable before by foot and therefore be able to do the things listed below, among others:

      i) greatly reduce travel time (by a magnitude of 5)

      ii) carry large amounts of produce/meat to local markets

      iii) fetch water from distant places

b)   A dynamo and a battery could be fitted into the bicycle. This could do a few things:

      i) power a LED fitted in the front and rear of bike to increase visibility

      ii) The battery would be charged as the bike is being ridden. The battery could then be plucked from the bike and used to power electrical appliances at home (mostly lights), or even a telepresence robot.
