I see winstanlays cycles are selling cube bikes with the bosch system for 2013. price range from £1849 to £2349-which has the nu-vinci system and 400wh battery. They also have a touring one with 400wh battery coming in at £1999.The only worry would be lack of support if anything went wrong.
The Epo 2012 seems like a good spec for the price, but I do get frustrated with high-end sellers who use such rubbish photos. Can barely see what it looks like on that website!
