Can't we use ( would ) to express negative past habits.?
The English British council says that( we don't normally use would with negative past habits. However, in Macmillan English grammar,the author says that we can use ( would never) and I came across such sentence ( His brother wouldn't ride a bike very often).
It seems to me that it is Ok to use the negative form ( wouldn't ) with adverbs of frequency with negative past habit or when it means ( he refused to...)
Would you please clarify this point?
Thanks in advance.
