Dumb Question of the Day - Pedal Size

[Kaizmuth]

I'm looking for some decent platform pedals for a newby rider that I'm guiding. I found some on Amazon that look decent for a great price, but they say 1/2 inch and several people comment on the size, but don't get specific about it.

They are going on a Raleigh 29er hard tail ($600 bike), but I'm not sure what the correct size is. I always just specify SPD or Eggbeater, etc. and never consider size.

What's the proper 'size' for this kind of bike?

These are the pedals I'm looking at for her: Required: Amazon.com: Diamondback Sound Pedal (Black Alloy, 1/2 - Inch): Sports & Outdoors

Any input not mocking me too severely will be greatly appreciated.

I'm betting it's the wrong pedal. The majority of mountain bikes these days use a 9/16" threaded pedal, not a pedal threaded to 1/2".

This is the one that will likely fit (I'm 99% sure)

1//2" are for 1 piece cranks, 9/16 are for 3 piece cranks.

So if it's not a Walmart bike, go 9/16. Thanks. The help is appreciated.

id recommend spending a little more and getting something with metal pins. its a cheap upgrade that makes a big difference on the trail.

edit: looks like the ones shibiwan recommended have metal pins.
