NOTE: 
While adjusting a loose hinge, slowly turn in 
1/16 increments. Failure to 
effectively adjust the
hinge could result in the hinge being too tight 
or loose. 
WARNING:
Failure to correctly tighten the frame latch 
can lead to damage to the bicycle or injury 
to the rider. Do NOT cycle with a loose 
frame hinge. 
WARNING:
If you are unsure of how to make 
proper adjustments to your bicycle, 
seek a qualified bicycle technician for 
professional advice on adjustments. 
Frame Latch
Dahon uses several different frame hinges on its 
bikes. Check your bike to see which instructions 
are applicable to you. 
The ViseGrip™ Hinge (also applies to the 
Vybe frame hinges) 
Tools Needed:
• 10 mm wrench
• 6 mm Allen key
FRAME HINGE CLOSED
FRAME HINGE OPEN
The most important part of a folding bicycle is frame 
hinge. Special care should be taken to check that the 
hinge is adjusted correctly before each ride. 
Use a 6mm wrench, an adjustable wrench or small 
pliers to tighten or loosen the hinge. Adjust the hinge 
bolt for the hinge to open and close with the correct 
force: 49-59 Nm for aluminum frames and 29-59 Nm 
for steel frames. 
Your frame hinge will need occasional adjustments 
from time to time. If the hinge ever becomes too 
loose it may need to be adjusted. Properly adjusting 
the hinge will eliminate movement or looseness. 
By tightening the hinge it will allow a strong seal, 
which will make the frame feel solid when closed. 
Facing the hinge head-on, turn the 
hinge latch bolt upwards. 
LOOSEN:
Facing the hinge head-on, turn the 
hinge latch bolt downwards.
