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.
