If you're considering a hardtail ebike
@tomato paste with a hub motor, I'd get her one of the NCM Bikes like the Venice or Moscow. From experience, they are very reliable, easily upgradeable and Leon Cycles (especially from when I liaised with them some years ago), have expanded their dealer network and their warranty service is on par with the top manufacturers. I remember I 'accidentally' tripped the BMS in my Moscow battery due to messing around with it by over-vaulting a different motor. Without issue and question, they swapped it (and this is me in the UK liaising with Leon Cycles in Hanover back in 2018 through my Amazon purchase). I was so impressed, I ended up buying my mom a NCM bike and she (along with myself), still own ours. Granted, I don't use mine as often but my mom does and thus, the Reention Darado batteries still get used.
If a mid-drive is more your wife's 'cup of tea', I'm surprised you haven't considered checking out Greatebikes.eu
They have some good options at pretty decent prices with motors ranging from Bosch, Bafang, Shimano etc. Hardtail, full suspension, touring etc.
One brand which may be a worthy consideration could be Crussis.
Hope you find your wife the best ebike for her needs
