Took my new cross core to the local velodrome and did some laps. Seems like the motor turns off before I reach the 20 mph limit. I was only getting up to about 19 1/2 miles an hour, and even for that, it took a lot of my exertion. Basically the same speed that I have ridden my analog Specialized Allez, which I do realize weighs a lot less, but I was hoping to be able to at least reach 20 mph without so much exertion. I did reach 20mph, but just for a few seconds.
