Single speed bike for sale - £150

I'm selling my Charge Plug Grinder as I'm running out of space in my flat.

It's this bike http://www.bikeradar.com/gear/category/bikes/urban/product/review-c... which I've owned since new. The bars have been replaced with bullhorns and the rear tyre has been replaced with a puncture proof Marathon Plus.

An ideal commuter bike, single speed means low maintenance and the mudguards are a bonus for the wet weather.

Size is extra-small. It's fine for me and I'm 5'5".

I run it single speed, I can provide the bits that came with it to convert to fixed (I've never run it as such).

Pedals are currently SPD pedals but I can replace these with normal pedals.
