Example of isometry between reflexive and non-reflexive Banach spaces

Question

Let $E,F$ be real Banach spaces where $E$ is reflexive. Let $i:E \to F$ be a surjective isometry. If $i$ is linear, then $F$ is also reflexive.

Could you give an example where $F$ is not reflexive?

Thank you so much for your elaboration!

Answer 1

Due to Mazur-Ulam theorem, there is no such example.
