EN-18 Original User Guide | Pedelec Impulse Evo / Impulse Evo Next Version 4
DANGER
It should be so hard to close the quick-release skewer that you need
to use the balls of your hands (120 N: corresponds to a weight force
of 12 kg). You should have the mark of the lever imprinted on your
hand. Otherwise, it could open when you are cycling, which could
lead to the seatpost coming loose and causing you to fall. If you close
the quick-release skewer too tightly, the seatpost can break; if this
happens when you are cycling, you could fall.
