I agree with gnat and Mr. Silver. Be honest with this guy. He put your bike up on the rack for you. That's a chivalrous gesture. Guys don't do stuff like that for girls they're not trying to get to know better.

I think if he was looking at you as just another riding buddy, he would have let you put your own bike up on the rack.

It's flattering, but I think the next time you see him, you need to be honest and let him know you're in a relationship, unless you're not sure about the relationship.
