One more note on average speed, that darling little compooter averages all time that your wheels are rotating. So, if you're walking your bike from the street to the house it can drop a couple of tenths just with that little 0.5 mph stroll. Just for fun, re-set your computer after your warm up and look at avg speed before you begin the cool down (in our case, time spent riding city streets vs rural roads). Avg time over an entire ride is very different than average cruising speed on the flat or average cruising speed in a pack.
