Small non-folding bike Are there any small non-folding bikes, of relatively good quality?

From what I see around, Brompton/Dahon produce only folding ones.

Ideally, should be under 10 kg, and have a few gears (but single gear is fine as well). I don't care so much about the structure (frame type/wheel size), as long as I can use it comfortably for short city distances.

I don't entirely exclude folding ones - but the folding mechanism clearly has a cost, and it's something I don't really need. The target is more a bike with small frame/wheels, and longer saddle/handlebar supports.

The Big Shot Mini Polo would be a good option, but the seller said they don't produce it anymore.
The A-Bike could be an option.

I'm a ~70/75kg 5'10" person.

====================

Post purchase edit:

I ended up buying an A-Bike, and while on paper it could be an acceptable bike, its engineering is a disaster.

Riding on 6" wheels is not a big problem. The problems are two:
- it's very, very hard to pedal
- the sprockets will consume and become unusable after sometime

This bike will not last more than a few months. DO NOT BUY IT.

====================

Right now, what appears to be a good option, is the Dahon Jifo - the price is unfortunately high.
Big Shot Bikes Polo Bikes are interesting and rather small. It does appear these are discontinued now.

However, Mixie bikes and the Salsa Mini-Velo are other small bike alternatives.
