I am working on the pieces of the frame for my Warrior trike project. I have questions about the frame height and pedals.
I plan on letting my wife use the trike and I don't want her to get hurt. I am concerned about leg suck. Therefore, I was going to put an old set of my toe clips on the pedals but it sounds like the toe clips may make the situation worse. Please look over my math below and let me know what I am missing.
Frame height above the floor is 11"
Frame is 1.5" square tubing.
Bottom bracket RADIUS is 3/4"
Crank arms are about 7" (center to center)
My toe clips position the heel of my shoes 9" below the pedal axle (in the down position).
That means...
11" + 1.5" +3/4" = 13.25" from the ground to the centerline of the bottom bracket.
Subtract 7" for the crank arm in its bottom position = 13.25" - 7" = 6.25" from the crank arm pedal tap to the ground.
Now consider the 9" overhang of my shoe off the pedal centerline and my heel should be 3" below the ground.
What am I missing? I've seen pictures of other trikes with toe clips and I didn't notice interference. I am clearly not thinking this through correctly.
