I would try to get the UFS frame only done first. I bet you will sell these as kits wired to a backpack, and the full productization is going to be a nightmare. Plus, I still don't love the idea of having the cells strapped to my feet, especially on an aggressive boot ... It's too tempting to do mean things to them Plus I like to have my feet extremely low and close to the frame. Thick frames are a bit annoying and make the skate feel vauge. This will be a problem at 30mph
I get your worries bro but don't worry I'm working to take these worries down :wink:

I'm guessing that after you build these gigantic frames and put 110mm wheels you'll notice that its way too tall to use with an aggressive boot. you have the 110mm from the wheel, plus let's say 10mm spacing and the batteries width that should be around another 50mm in which worst case (i know you have all the numbers) would give us a stilt-like boot 170mm (maybe taller) from the ground (against a 65-70mm normal UFS frame with 55m wheels). From my experience, aggressive boots are made to be flexible laterally to allow for grinds. I'm having a hard time with my Xsjados with the 125mm wheels which put me in 140mm height. You might need some ski boots of sorts.
other thing to consider is 4x110mm that would put you in 335mm wheelbase that its way too long for urban use, BUT would be great for those 30-35km/h speeds.
And lastly, 450Wh is a lot of weight. how much weight is that? I'm guessing that you are getting around 1kg+ just from the batteries.
if you add everything you will get a too tall, too long, too heavy, too expensive skate. It's fine for an experiment, but to make it a product it's a long shot.
what if you could reduce the height and weight by putting less batteries? maybe go for 3x110mm instead of 4x110mm to save on the weight of the frame and one wheel, also making it for maneuverable.
Nice video Ryu! Yea you need to smooth the plates with some teflon, it would greatly help and allow some side grinds I think.
Now dudes you're getting it all wrong with my soul plate, you greatly underestimate its features (and why I actually was so proud to post about it yesterday). And my frames are not that gigantic... Height is
WAY lower than you think.
First let me give you some numbers.
-Wheels shown on 3d model are 110mm wheels spaced by 2mm of clearance. That's 446mm total length for 4x110mm,
exact wheelbase of Wizard frames from Leon Basin and Mushroom blading and you guys know what they can do with these wheels. As it is right now it would still perfectly work with 90mm wheels, and it can go up to 3x125mm with a turn of a key.
Where Ryu is right is that nothing stops me to actually tweak it to be sized specifically for ultrashort 80mm or 90mm with same 2mm space between wheels, and make it capable of switching up to 3x110mm/125mm instead of being 4x110 / 3x125 capable. I'm sticking to this version because it actually helps me make sure of all size constraints plus I'm assured of its performance by this guy and his team :

-Total ground height of the rider with 110mm wheels is 155 mm, nothing close to 170 or anything more. With tweaks and hybrid materials I can fall under 150mm, for now I kept it simple. Maybe this is not visible but the boot actually sits in the baseplate, not on top of it. Put smaller wheels and, well you get the idea, it is already a ton lower than you imagine.
-Soul plate actually is 42mm
because of aggressive version, for fitness I could easily fit a 30mm max and get away with it.
-As sizes are, from 36 to 41 Soulplate would accept maximum 10S3P and from 42 up to 47, 12S3P. That's the maximum of cells it can accept, so less batteries are of course a possibility. Tweaking the batteries is a way to tweak the ride too!
Now I'll show you what kind of material I'm stuffing inside these and you'll understand why these are agressive soul plates designed to survive any goddamn abuse till the soul itself breaks or is worn by tricks. Remember also that the definitive version won't be a printed model, but a properly mold injected one, so even tests with the PETG printed version won't do it justice. I'm also using a thicker and more dense version than the pads shown in the following videos, and mine are guarded by the external material of the soul. BTW as I said before, these don't catch fire.

Remember I had Air treks in mind when I started this, if these are not worthy of being as extreme as air treks, it is a failed product for me. Also for kits, backpack is a bad idea above 350W as long cables cause surging and spikes, which damage batteries and ESC.
I'll be back later to give you weight figures with different battery setups, if I don't go now wife will K.O. me :lol:
