Creaky Dahon P8

I think I have the noisiest folder on the planet!
It sounds like a train passing, clickity clack with every crank rotation.
I first replaced the bottom bracket, and that silenced some of the noise
but now I hear the other clicking (creaking?) noises. It only makes noise
when I pedal and it gets louder the harder I pedal. The pedals aren't
making the noise, I'm pretty sure it isn't the seat post since it still makes
noise when I'm out of the saddle (which is rare but I wanted to check).
I even checked to see of the folding mechanisms were tightened properly.

So what am I missing?
Is there a place on the hinge that is obvious or prone to rubbing?

Next thing to check is the seatpost and saddle.

While you're at it, make sure the hinges are tight, but not TOO tight.

If it's a "creaking" noise, it's probably not the drive train. If it's "clicking" I'd concentrate on that.

Carefully go over the frame and check for cracks, etc. Hairline cracks can hide at weld joints.

Also check the handlepost hinge and headset. There can be a tendency to have the pulling forces on the handlebars keep time with your peddling. I ran into this on two Dahons.

A real left field possibility would be loose spokes.

Can you duplicate the sound off the bike?

My P-8 was also making creaking sounds, I put a tiny amount of grease on the handlebar and clamp as well as the sliding post extension, at the handlepost hinge and clamp, and at the seatpost clamp. I did not put any on the seatpost. This was done months ago and it has been quiet so far.

Most. The extra joints and hinges tend to really complicate the situation, and folding and unfolding tends to move cables, bump derailleurs, jam pedals, etc - making them wear more quickly or simply get out of alignment more quickly.

My old Speed P8 was always creaking - ranged from the pedals to the seat/seatpost to the hinges.

My newer BF just had a case of the creaks too. Lubed the joints and fixed that.

So yeah, most folders are more maintenance intensive then our fixed-frame brethren.

But they fit in my office and in the trunks of cars far better!

Hell no! So far my Birdy has needed minimal maintenance.

It folds at the front and rear suspension and a hinge in the handlebar stem. All have been maintenance free so far.

The only maintenance needed has been to periodically clean and lube the chain and replace brake pads as with any bike.

most dahon come with suntour folding pedals..they're heavy and the bearings inside will wear out after a few hundred kilometres..therefore it becomes damn noisy..

another part is the seat post holder..make sure it's not too tight..
