WM's policy is a strange one. I use Thameslink and Greater Anglia a lot - neither have an e-bike restriction (at least not yet!).
I bought my Fiido D11 direct here as it is/was cheapest and there are no issues if a warranty claim is needed. Fiido's UK warehouse is in Bath and bikes are sent by 48hr courier. There are a couple of stores in London that allow you to test, but none I know of in WM.
I'd say 5'6" is a good/natural height for the D11/21/X. I'm 5'11" - I added the riser bar in my pic for a little extra stem height and reach.
