Quick update.
On the very first run I decide just to take the bike around the block to get a feel for it, had so much fun I ended up doing almost the full commute to work on the weekend:eek: .
This thing really ate up the hills but It did have one big problem, the noise from the battery rack sounded as if it was going to fall apart over any small bump.
When I got back I strapped the battery down with a bungie cord and that seemed to help things.
On Monday I took it to work and it performed brilliantly with only some light pedal work needed to clear the largest hill.
Fortunately I work for an engineering firm so I took the opportunity to do some tweaking at lunch time. It was at this point I notice the rear derailer cable had come loose and that I had done the whole journey including the hill climbs in the highest gear set!
After fixing the cable, I lowered the rack and applied some tape and foam strips to various points and that seems to have fixed nearly all the noise from the rack.
The journey home proved to be a much quieter affair with only a small squeak from the front to track down.
On thing I did notice is that the battery locking pin does rattle when extended, not sure if this is normal or just a problem on my battery, I found putting a thin foam strip over the locating hole on the rack provided enough upward pressure to stop the rattle whilst still allowing the battery to lock in place easily.
So far I mainly using the pedalec function but I do swop to free mode when I want some fine control as even in the highest gear (on medium) this thing accelerates almost to fast:D
