This is my first post but here is the question. Which is your prominent or lead foot for your 1st power stroke starting off from a stand still? Mine is my left foot. I tried my right but it didn't feel as natural for me. It's been that way for the 20 years I've been into cycling some years more than others but now and again I try switching for a month and I only make it 1-2 weeks and I'm back to my left. What's your thoughts and idea's.

Left here too. One slight advantage for me is that many bike paths here have a sidewalk curb on the right making it a bit easier to put right foot down.
Mostly just a habit thang 'tho

I'm left handed and it's most natural, it seems, to mount from the right side and lead off with the left foot, but I usually ride fixed....I start of on whichever pedal is closest to being ready to go

There's more here.

a lead foot presses on the accelerator pedal , and drives faster than a lighter foot on the throttle.

then the Rt foot is for the gas, left foot for the clutch..

I guess I have ambidexterous feet. I start with either foot.

Right foot here.

I'm right handed and right is the "strong" side. However, it's easier/quicker to get the right side in the toe clip so, I lead with my left.

I am left handed and use my right leg to start off a bike. I get on the bike from the left side, like mounting a horse. The right pedal will have been pre-positioned at 2:00 o'clock prior to mounting the bike. When I come to a stop while riding I put my left foot on the ground with the right pedal already positioned at 2:00 o'clock.

Right is the correct answer.

Left because I mount from the left usually. However, the right works fine and I can mount from either side as needed. My right leg is most definitely much stronger, no doubt. Especially post broken left femur but still I generally lead from the left. I am right handed but not strongly so and often shoot (shotguns) from the left for example. I drive nails from either hand.

When I am at standstill my left foot is on the ground and right foot is on the pedal. Even when both feet are on the ground I always start with my right.

Right, since I always unclip my left foot (unless there's some really strange slope in the road).

+1. When I stop at a light and I'm near the curb, I have right foot up on the curb and left foot high. When the light turns green, I push off from the ground with the right, and stomp down with the left.

So even when I'm not at the curb, I do the same thing.

Left for sure. No other foot will do. (I also HAVE to put my left shoe on first everyday, but that's another story)

+1 lol

Left foot here. I'm ambidextrous. I think it's because I tend to swing my left leg over the bike when mounting.

right is right.

Right front foot

I never learned to mount a bike like a horse. I lean the bike to the left, throw my right leg over, straddle the top tube, use my left foot to position the pedal and then push off with my right foot (on the ground) and mash the pedal with my left. It would feel very weird to begin pedaling with my right foot and I don't know if I'm capable of mounting the bike from the right side. That would feel so weird I'm not sure I wouldn't lose my balance or get tangled up and fall.

I also put my left shoe on first....always.

Ambidextrous, I see what's more convenient for me to lean the bike on and unhook that foot to make the stop. When I'm mounting for the first time I mount mostly from the left, to start with the pedal that is easier to clip at the time. Double O
