I've arrived safely, it took me an hour to travel 10 miles across an 400 foot up and back down (I still want to know who left that hill there). There was one technical problem which added to the time and I'm not used to the route or the bike, I think that the journey time will end up around 40 mins (my best unassisted time for the route is around 1 hour 20 mins after which I was knackered).
I really like the bike, the killer hill wasn't a problem, the lesser hills were were negligable, and it was fun being able to coast around Canterbury in pure power mode.
The technical problem I mentioned was the motor not kicking in reliably. It was caused by the power cable getting between the bike frame and a thick plastic disc atached to the left hand pedal. The disc has some metal inserts which activate the pedel sensor, and the power cable had pushed them out of range. Once identified it was easy to fix, I just needed to reposition the power cable and push the disc back.
