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.
