My local Halfords closed down recently and was replaced by a Bike Hut and I'm pretty sure that they do have a Carrera Sparc on display in there. I went in there about a week ago for a browse and particularly noticed the bike (thinking to myself at the time that I hadn't heard the name mentioned on this site). I also noticed, on a separate occasion when I took my son's bike in there to be repaired, that Bike Hut was using Halfords stationary - so assume the two businesses must be related in some way - judging by the bikes on display, I think Bike hut must be the exotic Halfords.To add my 10p worth. The Carrera Sparc from Halfords would also fit into catagory 3 and is again significantly cheaper than the Cytronex in the order of things. The Carrera also has a proven, reliable motor and decent hub gearing. It seems to me a shame that this bike has been mostly overlooked as it was aimed at the popular market. I think that Halfords may have withdrawn it, as I can't see any mention in the Halfords 2008 catalogue. Maybe explains why models are heavily discounted. Another attempt consigned to the annuls of history?
