Platform Pedal Positioning

Hi All

I am looking into platform pedals and want to know if there is an ideal distance for the center of the platform pedal relative to the crank arm. Obviously people have different (width) sized feet and at least on some pedals you can get different length spindles, but is there a sweet spot in terms of distance from arm to pedal center. Its kind of hard to describe what I mean but I hope you get my gist.

Best

Arb

Whatever works for you is great. Your crank/bottom bracket may put a minimal distance on "Q-factor" (the distance between both crank arms), but pedal extenders are available to increase this distance, should you feel the need.

There's no sweet spot per se, but as a general rule you want your foot as close to the crank as possible, without touching.

That minimizes spindle stress and crank arm deflection, but it's not like it makes a world of difference unless you're strong and do plenty of steep hill climbing.

As close as possible, isn't always about the bike and pedals. If your natural foot orientation is with toes wider apart than heels, you might need to move out on the pedals to clear your ankles. Otherwise, the forced twist of the foot can be hard on the knees.

So, decide where your feet want to be, and buy pedals that will be well positioned under them.

The only "rule" I have ever heard is, ball of the foot over the axle, but this is why I like the platforms; after several hours and your feet start to get sore or stiff, you can position them any way you want.

This is interesting and helpful. So i wonder how these platform pedal manufacturers determine their spindle length and pedal position when they have so many different sized feet.

They design around the bike.

Wider pedals increase the possibility of hitting the ground when the bike is leaned, so they they try to stay as narrow as practical while still accommodating most shoe sizes. Sport pedals tend to the narrower end of the range, utility bike pedals toward the wider.

The only people with problems are sport riders with wide feet, or who need wider pedals for another reason.

I ride MKS Lambdas and move my foot position during rides based on degree of difficulty and feedback from my knees and feet. They're big enough that I can always find a comfortable spot fore-aft or laterally.
