Yes, I have one that I use for transport purposes i.e. going to the shops, a friends house or most likely the pub.
For this purpose the bike is well up to the task. I have ridden up to 40 miles on it and suffered no adverse effects, with respect to comfort.
I also have a road bike, MTB and Brompton, so for me it is part of the fleet and used for a specific purpose, at which it does well.
For me, I wouldn't want to use it for something other than transport or the pub, but that's because I am lucky enough to have different bikes for different purposes.
Could it work as a standalone, clearly yes, but if you didn't need it to do everything and were only looking for one use, such as road, then a specific road bike may be better suited. Possible a jack of all trades and while it is good at them, it is a master of none.
If you have any specific questions, do let me know.
