Do you remember how much fun you used to have when you rode a bike as a child? No one ever really forced you to do and and you couldn't wait to get home from school to go ride with your friends.
As you grow up you look forward to driving and you probably left your old bike alone and maybe you haven't ridden a bike in years. Maybe you don't find it fun anymore.
Is it still fun to ride a bike? Of course it is. Many people still do it for fun, exercise, leisure well into their adult lives and you can too!
