It seems some pedals are 15mm and some are 9/16. I'd like to replace the pedals on my bike.

Here is the link to my bike. My owners manual is very generic. I can't find a 'service manual' (if anyone knows where one is I'd appreciate it) - so by looking at this will these pedals fit this bike?

Thanks for help on a basic question like this - I appreciate it
