Hi i want to learn to ride a bike but can someone answer some of my questions? First off, i heard that you have to look up when riding a bike and sit up but i always see guys ducking under the windshield and i was wondering why that is. My second question is when do you countersteer? Can't you just look at where you want to go? Final question is i know that when your bike sounds like a lawnmower is when you upshit but how do you know when to downshift? Thanks.
