Thanks guys, I found a number of sites selling both the Comfort GTS (which I promptly bought one of) and the Lite 2006 models available in the UK, you just have to persevere. It seems that the most effective search criteria was 'Giant Twist' in google.co.uk. I found the Comfort straightaway, but it took a couple of hours to find the Lite.
Flecc, Duct tape - right, I'll get some.
More first impressions..I Notice that this one has the SRAM P5 gears and the front hub is a Nexus dynamo attached to a Lumotec front light (the rear light being an Led). The tyres just say 'only for electric bike' and dont appear to be any particular make, but they do say 'MAX 85Kg', which I hope wont be too much of a problem (me weighing in a tad above that). The rear carrier has 3 elasticated straps over the top of it, I assume they remove somehow, but the manual Ive been sent is the 2001 manual for the 2002 model, which is nothing like it (it talks of 3 gears and rim dynamos!)
I plan to take it for a ride at weekend all being well (if I can resist till then).
