I now figured that you've got the Santana CD. It was later replaced by the Rambla in 2019. The Ramba has better crank motor, Bafang MaxDrive and 9-speed cassette.My woosh santana arrived in May 2014 and looked like the second picture you posted. I think it was £779 when I bought it.
Santana-CD: revolutionary when it was introduced, step through, crank drive and throttle:
