Question: are bike pedals universal fit?
Answer: Bicycle pedals are not universal. ... The 9/16” is the near-standard in bike pedals, meaning that the majority of bikes can fit a 9/16” pedal. But since the 9/16” is not the only pedal size available, it can't be truly said that bicycle pedals are universal. Luckily, there is an almost-standard pedal size available.
