Guy's Behavior

Are these signs he secretly loves me or has a crush? Why is this shy guy acting this way?

So, I'm inexperienced when it comes to dating and relationships. In Feb 2020, I sent a FB request to a male co-worker, because I (female) developed a crush on him. We had many things in common, so he asked me to go on bike rides with him. We connected on Strava and went on 3 rides total. I tagged him, but he only accepted on 2/3 rides. I was hurt he wouldn't acknowledge our last ride, so I figured he was no longer interested. Skip ahead a few months later, he gave me his used bike computer as a gift. Realizing he could've sold it for money, but he said it's a gift, I was so happy. When he comes by my dept, he was nervous, fidgeting, wipes his sweaty hands on his pants, stares at me, but looks away when I look at him, and he will walk down a hallway in my dept, turn around, and walk back out. Lol He showed concern for me making sure I got to work ok during bad weather, and he helped fixed my bike and computer. I gave him a hug, but he patted me on the back. When he left, he made a joke and said, "I'm locked in your apt." We have gone on more bike rides together since then. He said he only sees me as a friend, but acts opposite. Other co-workers thought we were dating in 2021, because he came around so much to flirt. In 2022, I gave him a gift for helping me and he accepted. He was extremely nervous, fidgeting, touching his face all over, etc. I again asked how he feels, and he said he only saw me as a friend. I finally told him I cared for him, I was interested in him more than friends, but he refuses to ask me out. He is very hot and cold with me. Sometimes he texts back right away, other times he leaves me on read for a long time. He has never called me. Please help. I can't figure him out.
