After much deliberation and quite a lot of searching especially on the forums here I last week ordered a 2009 Wipser 905SE City. I intend to use it for work 38 or 28 miles per day round trip depending which site I am based at. I currently use a standard bike but my old rugby knee injury is a killer on the hills(not that there are that many in Norfolk). Anyway just a thank you to all the people who have helped me in my dicision. I will post again once I have recieved my bike. I will be upgrading the seat to a Rido R2 and putting my BikeBins on it and then will be giving it a go. I currently average 15miles per hour on my Raleigh but my knee takes about 4-5 hours to recover from the trip. Hopefully this will help!
I'd just say, to get the most from it, take your charger to work (or get a seccond one to keep at work), as I know from experience that if you hit an East Anglian head wind - it probably won't make your distance on a single charge.
