The bike does not have the crankset or the gear shifter as they were used for another bicycle; however, before the change, it worked without any issues.

It therefore needs to be repaired by installing the missing parts.

The rear shock and the fork work; the rear shock has not been serviced, so it likely needs a check.

The saddle has a cut and needs to be repaired.

Some stickers on the wheels are partially peeling off.

The frame has sun-faded marks in some areas.

Regarding the size, I believe it is an M; I am 1.80m tall and it fits me well, but I do not know the exact size....
