Well I feel rather embarrased.  Once i unboxed the bike, i paniced as it looked massive.  Being a roadie, I did not expect the handlebar to be at nearly chest height.
The good news is I have now ridden it a few miles.  The saddle is still too low and I need to raise it.  The bike actually feels fine to ride, and I think a Large may have been too small. 
All I can say is WOW!  An ebike is a revelation.  just anoying that the motor cuts out at 15.5mph.
