I'm in the opposite team, when I ride I fall asleep very easily. At least now. I remember that when I first started doing activities like running, pilates and then, cycling I had an awful time trying to get to bed early. I believe it was the adrenaline rush after a workout. But after I got used to working out regularly at night, my body settled and now I don't feel that rush for so long (it usually goes like this: get home, eat something, pass out watching the news)
I think like, as someone else mentioned, it might be because you haven't done physical activity in a while and the adrenaline rush is keeping you awake. It'll take some time to your body to accommodate, but it will.
