Then where to place the battery ?

Looking at the detailed pictures, I do not find the welding amazing, actually several welds are questionable (look for instance at the picture with the serial number for instance). But seen the low price of the bike, it seems normal).

I have see also some design weaknesses:
- the seatpost locking seems to me really basic and not made for a folding bike where the seatpost must be unlocked/locked each time the bike is folded.
- the helical system for the rear arm and fork folding that is very much exposed to dirt, what will happen when the bike will be folded with dirt (or mud) inside the hHelical groves.
