One pedal is not allign anymore, and i need to buy a new one how to know wich FOLDABle pedal is compatible and where to buy?

Measure the pedal thread size. Most likely 1/2 or 9/16 and buy the correct size. Roger

hi
what tool do i need and how to i mesure that ?

would we have the info you say is needed if we find the spec of this bike?

The first question is whether you have 1/2" and 9/16" open-ended wrenches? If not then 13mm is close to 1/2" inch and 14mm is close to 9/16".

The first step is to remove the problem pedal.

Next try to fit the 14mm-9/16" open ended wrench over the threads that you have just unwound from the crank. If the wrench fits, and the 13mm-1/2" wrench is not even close to fitting, then you have a 9/16" pedal. If the 14mm-9/16" wrench is a very lose fit and the 13mm-1/2" wrench fits then you have a 1/2" pedal.

i used a 1/2 and 13 mm and both mouths are too small . so i have a 9 .16.

i never had to buy a folding pedal, tx for the help by the way.


do i need to mesure the width, long and height?
what esle is needed for me to know?
maybe you can suggest material ?

hi
eng sec language , what part of the pic do you call a tread cause to me a thread is the multiple valley succession and it is not accessible cause it is screwed in...

first trip

here are 2 choices . left an right

the no 3 review are saying that The only complain is the bearing is not smooth. they are terrible.
how does a not easy bearing influence the pedaling xp? does it add friction hence harder to pedal?ly but the bearings are very stiff and clunky feeling.

I have never had folding pedals either

Yes, the 'threads' are those multiple valleys.

After you remove the pedals, try fitting the mouth of your 1/2" and 9/16" spanners across those valleys, or just measure across them with a tape measure. That is the only measurement you need to do, because they are very standard. *Generally* small child's bikes have the 1/2" pedals and *generally* adult bikes have 9/16" - but for specialist bikes like folders anything is possible.

The bearings in a pedal should feel smooth when the pedal turns, because our feet are sensitive and we will feel if it is not easy. I break and rebuild bikes, and I always test the pedals because people notice how they feel.
