First motorbike help? 23, roadtrips + city living?

I'm unsure what bike to buy… I have been looking at the Honda Grom for practical reasons (MPG, reliable etc) but i love the look of the Keeway Superlight and is the design style I imagined myself riding.

I just finished university and live in the countryside currently but i will probably move to London after my gap year.

On the gap year however, I'm going on a 5 month adventure around Europe.

I'm not adverse to fixing my own bike, i'm aware the Keeway has mixed reviews but i really know very little about motorbikes. Will I be missing out on a biker experience if i got the grom? Should i just save for the grom if i did go to london? Is the grom actually fine in all aspects or is there another bike you would recommend…

Opinions?

Thanks in advance.
Added (1). Also, i'm aiming to spend less than 2k (around 1.2k ideally) and looking to get a used bike but there's wiggle room.
