It's an s6l b spoke and whent for the marathon tyres the shimano hub dynamo Brooks b17 mini o bag the colour was the hardest thing to chose really liked the arctic blue.
I am a bit of a bike collector I have a few 16 inch wheeled bikes and must  say Brompton is very good I have a lovely 1964 moulton  they both ride very similar I don't get no front end movement and I can ride both with no hands I have a dahon curve that you would not really ride one handed so bad it would be a hard choice to say which is the best between the moulton and the Brompton but I would say that they are great design bikes the genius of moulton and the total practical Brompton both are beautifully made
		
		
	 
Smitten!
I have to say that riding the Brompton for the first few times really reminded me of riding a Moulton Mini when I was a kid.  And to be fair riding the Brompton  makes me feel like a kid again. It's so nimble, agile, fast accelerating that it makes my racier bikes feel like barges.
My justification (apart from I've always wanted one) is that I take it abroad on business trips in an Polaris EVA bikepod so that during downtime I can get some exercise.  But, what I'malso finding is that I'm starting more and more to use it as everyday transport; to the shops,on local errands, to work even walking the dog!  The Saddle-bag bodge has worked so well I'm also considering some simple touring on it too.
I'm loving it ....
