I did not. My Levo seems to cut out about 17.5 - 18mph. My LBS asked the Specialized rep about it and he said that sounded right. I wish it would power to 20mph but it doesn't sound like that's going to happen.
No. As far as I can tell this has to do with the new Mission Control app. Unlike the older version, the choice of wheel size must be selected from a list that goes no lower than 2000.
