A bicycle is traveling North. The direction of the angular momentum vector of it's front wheel is?

I chose "North." The answer is West. Why?
thanks

Look up right hand rule for vector products.

The direction is given by the right hand rule.

$\hat{L}= \hat{r} \times m \hat{v}$

My mistake. I know nothing of this topic, I should have looked before asking...
