Should I buy a scooty or a bike?

So my flatmate got a gf, so now he and her go to the gym on his scooty, which was earlier used by me and her.

So now I am thinking to buy a vehicle but confused between a bike or a scooty.

Scooty comes with boot space where you can keep the helmet and other small things.

But a Bike feels more manly and I can go on long rides on a bike.

I might get married in next 1 year so if I go with a scooty my future wife can also use it while she may or may not use the bike.

What do you folks think?
