as i said on the twitters they're not a bad pushy at all - just the wheels might need changing out if you ride it a lot - ask the cell dudes and they'll probably say the same and get you a stronger wheelset - look at this - http://www.cellbikes.com.au/Sturmey-...Hub-700C-Wheel

gives you an extra gear on the fixie as well

on a side note, the new cell omeo range looks absolutely brilliant for the price points - di2, full carbon etc on the 2.0 for under 3k - beaut looker as well. the 1.5 will come with an SRAM gruppo, dunno if black or red but i think i know what my next treddlie will be
