Dole duly paid by Centrelink. I was asked and have confirmed my intention to attend the Certificate IV in Small Business Management starting January 7th (NEIS allowance may apply).

I had a look at the bicycle and came to grips with a cheap pump and the valve (which it seems is a Schrader valve rather than a Presta valve). The first thing that happened after I applied the pump connector was that all traces of air disappeared from the tyre - so I attached the pump and pumped. It appears that there isn't sufficient energy in my arms to pump the tyre to full pressure so I read up on bicycle pumps (and valves) on Wikipedia.

Wikipedia (somewhere) tells me that a "floor pump" is a must (not a foot pump) so I went into the bicycle shop in Penrith (where I purchased the bike) and asked about the type of valve fitted to the bike and "floor pumps". I was sold a floor pump with connectors for both a Schrader valve (http://en.wikipedia.org/wiki/Schrader_valve) and a Presta valve (http://en.wikipedia.org/wiki/Presta_valve) and a lock to "lock it in". ($45). It also comes with a pressure gauge which is seemingly standard - but in my case doesn't appear to register anything. There's no doubt the Schrader connector pumps air into the tyre and does so with just a few strokes - but it would be nice to know the tyre pressure (which for the tyres on the bike should be between 40 and 65 psi - inscribed on the outside of the tyre).

I have no psi reading from this Topeak "Joe Blow Max 11" pump (http://www.topeak.com) despite the nice yellow gauge. The tyre is well inflated but it would be nice if the pressure gauge worked. I may take it in tomorrow and discuss exactly how I am supposed to use this pump. It appears to be obligatory for the pump to allow air to escape before locking - after which pumping is very easy and there is little leakage on removing the pump.

Bottom line - the pump works - the gauge doesn't.

There isn't much for me to do now - apart from wait for Christmas and the New Year and contemplate 6 weeks intensive study from January 7th.
