ok so why don't pedal spindles thread in the back of cranks then you attach the pedal body I would of thought this would be stronger. I had some other ideas so I will come back and add ideas

Beacuse you would then be left with looseball bearing adjustments on cheap pedals, and then something else sticking out meaning your crank arms would have to be further out from your frame to avoid contact with your chainstays, causing more headaches.

Plus more parts = more to fail.

I was thinking more like animal BPE's with bushings also the piece at the rear of the crank would only have to be tiny. If it caught on it could be recessed into the crank arm.There wouldn't be more parts just more strength

Also, it would limit the size of your spindle to less than 9/16" or about 14mm. For reference, JCPCs spindle is 14.5mm thick at the thickest point (Not including wrench flats). My pedal design is quite a bit bigger still. So it might be stronger than most PC pedal spindles but it would limit strength.

Why try to fix something that isn't broken? I've never seen someone break a pedal spindle in my life. Seen plenty of pedals break but never a spindle.

I've seen a few spindles break (Namely Fly Ruben), but the main concern is bending. Bent spindles are extremely common especially in plastic pedals.

In my 20+ years on bikes I've never seen it, but I'm sure it happens out there. If you're worried about it then stop buying cheap plastic pedals.

I don't. But I did bend my Fly PCs when I had them a couple years ago, my friend bent his Animal Hamiltons really bad, my friend bent his Premium and Demolition spindles enough to be noticeable... that's just to name a few. But I have been on Trailmixes for 3 years before I sold mine and they didn't bend. Trailmix and JCPC spindles are ultra beefy. Still possible to bend spindles on high end pedals, though (Looking at you, Fit Macs).

You're thinking, and that is good, but I don't know if creating a new pedal standard would really take off, especially if the strength to weight ratio is not drastically different. It would take a lot of R&D and a lot of work to make it cost effective, properly functional, and these companies would have to redesign both pedals AND crank arm pedal bosses to accommodate, which would either mean creating double the products (or guessing correctly the amount to build of either type) OR they would leave the folks who don't upgrade out in the cold if they just stopped making the current standards.

Also it would likely mean more weight.

Maybe instead of using forged materials (cheaper and usually weaker) get in on some CNC action for high end pedals?

man i love it when people start to think out of the box. And the whole "If it aint broke dont fix it" Is the worst ever. How do you think we got female hubs, straight pull, cassettes, spline drive and non threaded stems in bmx the more people in bmx like this the better.

OP great work keep thinking and make some designs on paper and see what you can improve.
