I've only had the bike for a month, so still early days and review may change, but so far I have to say its exceeded my expectations.
The folded measurements published are accurate so it fits nicely. And in general, the bike is as described.
General quality seems good and the folding and unfolding process is fairly neat and easy.
I did a few trips of about 16 miles of riding (8m each way) , which was probably further than what I thought would be manageable on a bike of this size, and while you can't compare it to a proper size bike, it was completely doable. With appropriate maintenance needed for every bike, I can't see a reason why it couldn't last long.
