What tool do you need to remove a bmx freewheel?

Answer 1

you need a freewheel remover. but if you don't want the freewheel anymore a vise also works too but don't clamp it down to hard just get it snug then spin the wheel so it spins off the freewheel cause some bike shops charge like 2-5 bucks to take it off
