----original (german) version----
Honestly, I think the idea of sustainable pedals is good, but I don't think it will either. There are simply too many "giants" on the market that do this better. Hope, for example, also produces in the UK, maybe not with green electricity, but probably with the material. And since a good 200g less of said material is used, the Hope may ultimately make more sense. You should also consider that a large company like Hope probably produces in shifts, so it gets a lot more out of the machines. And above all the most important point for me, at Hope I get spare parts, probably even after 20 years. I don't want to talk bad about a small startup, but if I need a new sealing lip in 2 years because I have damaged the old one in some other way, then I would like to have one, otherwise the rest can be fair and sustainable. And Hope is not alone there, in the USA there is for example Yoshimura, also from UK the unite pedals, and probably many more that I do not know. And all of them look like a more mature product than the pembree.
Honestly, I don't think the pedals are an engineering feat, the pins are probably exorbitantly expensive, you could have simply looked for a European screw manufacturer and ordered a few m3 screws there. costs a fraction and at the same time offers a better supply of spare parts (see e.g. one up pedals).
Also, I don't quite see the point of two deep groove ball bearings, other manufacturers can get by with one (and ball bearings are heavy!) And if there are two rows. Since I don't have a FEM on the pedals, of course, that's just a guess. And as a screw head for little space, a slotted screwdriver has proven to be useful, you don't have to reinvent the wheel right away.

If im honest, I think sustainable pedals are a great idea, but I doubt this will be a success. There are just to many "giants" dominating the market for pedals. Hope for example manufactures in the UK, and although maybe without green electricity, at least while using way less material. And because they use around 200g less material, they might even be more sustainable. You should also consider that hope manufactures using shift operation, so they get more out of their machines. The most important point for me however is, Hope offers spare parts, probably even in 20 years. I don´t want to critisize a small startup, but when I need a new seal in 2 years because i fucked up, I really want this seal, the most sustainable pedal is useless if it´s trash due to a small spare part. And hope is not the only company giving me this kind of security, In the USA there are the yoshimura pedals, and also in the UK the unite pedals, and probably a lot more I have never heard of before. And all of them seem like a more mature product than yours.
If I am honest, those pedals don´t seem like an engineering masterpiece, having pins like this is (probably) extremely more expensive than just using (european made) m3 bolts, that also give better Spare part availability (See for example One Up pedals)
I also don´t see the need for two deep groove ball bearings, other manufacturers don´t need theim either and bearings are really heavy. And if you really need two, there are double rowed ones. Considering I haven't done a FEM on them, this is just a guess. I also don´t see the need for the special tool, if you have not a lot amount of space, why not just juse a slotted Screwdriver?

Thanks for the translation it is greatly appreciated!
Our seals are through SKF and are standard products that have been produced for many years to ensure that spares will be available. I know PEMBREE has just launched by I have vowed to have spares for all products for 10 years.
The reason for the paired ball bearing is to reduce wear, ensuring the pedal will last for many years.
