Nice pictures! Can you describe how much of what we see is your modifications and what was original? Are your pedals and cranks original?

My Mobiky came with a Sturmey Archer 3-speed hub, which I like, and I believe they are all sold that way here in the USA, but I know the equipment is different in other parts of the world.

I too changed to a Brooks leather saddle. I used the shorter B17S model to better fit behind the carry handle when the bike is folded.

Did you rebuild the front wheel yourself on the Hope hub? I built my own front wheel with a Schmidt SON20S generator hub to power front and rear lights.
