Frame Latch Adjustment
Instructions
The frame hinge is the most impor-
tant part of a folding bicycle. Care
should be taken to check that the
hinge is adjusted correctly before
each ride.
Your frame hinge will need peri-
odic adjustment. If there is play or
looseness in the frame it may need
to be adjusted. A properly adjusted
hinge eliminates play or looseness
and a correctly tightened hinge will
close with a strong seal, and the
frame will feel solid.
WARNING: If you are in
any way unsure of how to
make these adjustments
yourself, take your bike to a
qualified technician for profes
-
sional adjustment.
WARNING: Failure to
appropriately tighten the
frame latch can lead to damage
to the bicycle or injury to the
rider. Do NOT cycle with a loose
frame hinge.
Dahon uses a variety of frame
hinges on its bikes. Please check
your bike to see which of the fol-
lowing instructions is applicable.
The ViseGrip™ Hinge (also ap-
plies to the Eco frame’s hinge)
Use a 6mm wrench (if you do not
have the right sized wrench you
can also use an adjustable wrench
or small pliers) to tighten or loosen
the hinge.
Adjust the hinge bolt so that the
hinge opens and closes with the
correct amount of force which is
49~59 N for aluminum frames and
29~59 N for steel frames.
NOTE:
Adjust in 1/16-turn incre-
ments only, otherwise you will
quickly over-tighten or over-loosen
the hinge.
