I know nothing about fixies and I have a few basic questions.
I understand there is one gear. Do you have a choice in gear when you buy it? i.e. if you are in a hilly terrain can you choose an easier gear?
Is it possible to have a freewheel with a single gear, or does that defeat the purpose?
Do people typically have brakes or do they just brake with their legs? Is braking with your legs hard work?
