@ Jeff, my apologies ha ha, i think i had too many Threads open in my tabbed Browser, must have mixed up two replies. So though inappropiate, not non sensical i think Hope you don't mind too much?

Also, yeah that is the "dichotomy" problem with employment often. Anything that has a decent salary tends to be desk work that very often is full time. While part time work often pays less and can be a little more "free".

I am pretty lucky. I am a part time nightwatch (and can live off the pay and even buy some bike stuff) which in practice means 3 hours of work and up to 5 hours of (bike forum) surfing though i usually am rather tired after 2 hours surfing and do something else.

@ Foible, from what i understand the added momentum is minimal (especially if you get fast slicks) and it does not at all weigh up to the improved acceleration (i smoke all the other commuters at traffic lights ha ha and climbing. Other benefits: the slightly shorter wheelbase allows you weave in and out of traffic without and drawbacks (axle distance is the same as is riding position on a good folding frame) lastly 20 inch is BOMBPROOF! Just look at BMX ers, i have tried my utmost to get a warp, impossible!
