I notice a lot of the newer Dahon folding bikes come with Lock Jaw folding hinges. I have been unable to find a picture of these hinges. I would also like to see the folding in action. Where can I find a picture of these hinges, both static and dynamic pictures would be great.
Any commentary on the strength and/or durability and stability of these newer Dahon hinges?
Regards,
PCG

Well, I guess the Dahon Lock Jaw folding hinge is a very well kept secret!:D;):rolleyes:
Or, Dahon has never sold a bike with this hinge arrangment?:eek:

I just converted my Cadenza to fixed gear. Hopefully the hinges will hold up to the extra stress. I'll post more comments after several rides (maybe some pics a little sooner).

What model year is your Cadenza?
Does it have the newer Lock Jaw Hinges?
I will be waiting to read your next post after your experiment.

It's a 2007 model. The first one with lock jaw.

I just wrapped the drop bars that I put on it today so I'll have pics soon.

I just saw a picture of one on the "Crazy Guy on a Bike" website.

They were riding full sized Dahon folders around India. You can see the picture below and the bikes on this web page:

The Dahon Lock Jaw hinges appear to be constructed of aluminum. Aluminum is quite a soft metal. I wonder how the aluminum locking surfaces will hold up with a routine of folding and unfolding. It seems to me that the soft metal will be compressed and worn away in the locking area and become less than tight after several months of use. Any first hand experience with the durability of the mating locking surfaces?
I would hate to end up with an articulated bicycle frame. I wonder what the warranty by the manufacturer is for this frame hinge?
