Seat
Assemble the seat (10) on the seat post welding sets (9) by using the flat washer (17) and the
knob (18). Insert the seat post welding sets (9) into the main frame (1) and use the ball quick-
release knob (31) to lock the seat post.
The seat (10) can be adjusted according to your personal need by loosing the knob (18) –
see the above small drawing "backward" / "frontward".
Then, loose the adjustable knob (31) on the main frame and slide the seat post (9) onto the rear
stem of the main frame and secure with the knob (31) in a proper height.
How to use the knob (31):
The seat support tube can be fixed at various heights by loosing and pulling out the knob (31),
adjusting the support tube to the desired height and then fix the knob (31) again properly.
The seating height is correct when the knee is slightly bent with the pedal vertically downwards
and the foot parallel to the floor.
