Cant wait to try it out. The only thing that worries me is that I am 6 foot and I ordered the Xlarge. Its just a little smaller than my RadRover 6 by about a half inch and Its the perfect size. Im hoping the geometry isnt that much different. The large and extra large are both rated for 6 foot. The Serial 1 is the reason I started looking for Ebikes. I thought it would be cool to have a Harley ebike but I couldnt afford 5 grand. With the sale I couldnt stop myself from buying it. I would just about order it and then cancel it because I just bought my RadRover.6. But, then i would try to buy it again. Its gone on for two days. I finally just did it. I got my Harley, Im broke now, so, I should fit in.
