I'm on the verge of doing the same as it just seems unbeatable price-wise. Would want to add mudguards, rear rack and kick stand. I'm assuming that's straightforward.
Would have liked integrated front and rear lights but that's more a nice to have. Would transfer my Brooks saddle. Not sure if I might want to put different handlebars on it. Think I might be over-analysing things? Just keep coming back to the great price. Buy now or pay more for something better later? I'm 66 and there's still a bit of me that's resisting that move over to an electric bike but I do find some of the big hills a bit of a challenge nowadays but I just love to go off on adventures still!
