Notes: (added 18 August 2013)
1.  Clarification of One Hand Rule
Each claim has a set of "elements" that defines the invention.  If the claim has many elements then it would be very long especially when you cannot even cover it with one hand.  Just as in the case of the bicycle example, the more elements there are the easier it is to avoid infringement on a competitor's patent claim by not including in your product one of more elements mentioned in the claim.  In other words, a claim that has excessive number of elements is necessary a narrow claim.  

2.  Why do you want to include as much detail as possible in a patent specification?
There are two reasons for it.  Firstly, the government want you to give a full disclosure so that when someone else is reading the patent, they can reproduce your invention.  Secondly, the more you disclose with respect to your new teaching the broader you can claim your invention.  In other words, you can only claim your invention if it is mentioned as new teachings in the patent specification.
