Road bikes
If you want to end up in the European pro peloton, you'll need to devote 100% of your life to riding from now 'till you're 40. Tell the parents that you will not be going to college.
It's more than about riding a whole bunch. It's a lifestyle that you need to devote yourself to completely.
P.S. This is not to say that pro riders are uneducated dolts. There is however a large precentage of the peloton who never graduated high school or went to college.
