Should I still go biking with him?

Hi, I'm torn.

I've just started mountain biking and went to a dirt park. It took ages for them to convince me to jump a drop. The others cheered me on, and he laughed at me because my riding was rubbish. Then he told me I should jump a double, and I didn't. The others accepted it, but he made fun of me. On the way back, he told me that the others had been gossiping about me, saying I didn't deserve the bike, that I was crap, and that my hair looked like a blade of grass even though it was done. He thinks it's biker logic, is that right?

Afterwards, we talked about it at school, and he said I should start with tables, which is how he started, and he sucked. Two hours later, he said he and the others had done much better, and I should just do the double because otherwise I wouldn't be a biker, even though he can't even do a tabletop himself and feels way too tough, and he's not helping me with the rider anyway.

PS I've been driving for a WEEK
