When compared to other bikes, his price was too high

[Hansman]

When compared to other bikes, his price was too high.

Which one is different from the original sentence?

1) When it being compared to other bikes, his price was too high.
2) When it was compared to other bikes, his price was too high.
3) When being compared to other bikes, his price was too high.
4) Being compared to other bikes, his price was too high.
5) Compared to other bikes, his price was too high.

The answer is #1. However, I think that the pronoun of ‘it’ is his bike, not his price, and then, the two subjects are different, so ‘it’ should not be omitted. And then, I think that only #1 is the same as the original sentence.
And have you ever seen #4 one in your life?

What do you native English speakers think? Thank you so much as usual in advance.

It is an English question on a test at a school. And the answer was only #1, but now #2 is also acceptable as an answer.
However, I think that the sentence itself 'When compared to other bikes, his price was too high' does not make sense.
If I rewrite it to When it was compared to other bikes, his price was too high, what does 'it' refer to, his bike or his price?

Or should the sentence be like these?
When compared to other bikes, his bike was too expensive.
When compared to other prices, his price was too high.
When it(his bike) was compared to other bikes, his bike was too expensive.
When it(his price) was compared to other prices, his price was too high.

or is the original sentence 'When compared to other bikes, his price was too high' acceptable?

It is Korea's middle school.
Actually, I do not care about the answers, but I would like to know if 'When compared to other bikes, his price was too high' makes sense or not.
And when it is rewritten to 'When it was compared to other bikes', his price was too high', what should the 'it' refer to, his bike or his price?
What do you think? Thank you so much.

Try:

When compared to what other people were asking, his price was too high.

The original compares "bikes" and "price".

 

[Hansman]

The original compares "bikes" and "price".

Thank you so much. Do you mean that the original sentence 'When compared to other bikes, his price was too high' does not make sense, right?
