I’ve ridden for 30 years.
Still hitting the main jump line at 45, my kid rides better than most on the mountain he’s 10.
The motor hovers above the snow line allowing you to ride. It disconnects in 30s
This was designed to surf hills, ride in town, cross country trails, cruise, backcountry access. You name it.
I just want to allow my kid to ride everyday and needed a good job in order to move to Mammoth. This was the best way I could think to make that happen.
@Alpacaslapper the rear felt like the best spot to drive from.
It also allows the arms to flex torsionally through the motor to control it a bit with your feet.
Lean back to dig in deeper.
I think 40ft rooster tails out the back will be cool af.
Suspension: Shore hardness determines flexibility. We will make them as loose as possible without eating the board. The first ones have 150mm travel.
Sorry can only judge from the video and the initial design concept. however I still think having something trailing behind is a dumb idea. having a kit that you bolt on to the middle of a snowboard would be better in my opinion. I think having a football like profile might be the simplest way to do is so you dont have to have another dimension to the worry about providing you get enough grip at different angels of lean. so something like a large hub motor might be able to fit in the core of the paddlewheel.
@Schtekarsten The guys at arbor said they tried a one wheel style but could not say much (NDA)
I want to ride down without it. That’s the consensus from the riders feedback so far.
The idea is to get it to float 6-10" pow, low angle. Surf it like a mini snowmobile.
that was the early ideas of electric skateboarding as well. get pulled up then ride analog down. I thought the whole point was to be able to carve around no matter the gradient.
I like that design a whole lot better and maybe it is like skateboarding that you wont speed check as much when you have a remote and paddle to control the speed. and a lower radius deck is what controls the majority of the turns.
I just dont like the idea of throwing a board sideways with that beast of a thing at the back. but on the other hand you dont have to care about deck cutouts, rigidity, and get snow propelled around from the middle of the deck. idk.
As the snow gets deeper the drag sucks snowboarding especially at low angle. You end up riding 5mph.
The wheel hits 2150rpm @ 70V, options to 120V. It should be its own experience if she floats no resort required. Future models will be smaller, and lighter. It would cost a fortune to design from scratch. Kinda had to work with what’s available to begin with.
I have no idea about what kind of power is required but I can imagine so and that is why I think the tech might be a few years away unfortunately. the higher the voltage the better sure. but you can change the kv of the motor to have it spin faster if that is what you are worried about.
Might go the other way and add 2:1 gearbox to get more uphill torque. 150/Kmh might be a little much.
This is so cool. I really love how this isn’t just a side project but an actual job. The thought, materials and design are all appealing to me.
I live in the 3 Valleys, just 20min from Méribel and 30min from Courchevel, in France. We get plenty of snow in the winter and something like this could be go cool and practical… And something to show off with 
My main concerns would be as you mentioned, being able to ride downhill freely or somewhat recreate a natural carve without feeling a drag
Weight… I don’t know how much your prototype weighs but given the two motors are almost 2kg, I’d assume the total weight would be between 2 and 3kg without a battery.
And Noise… Obviously in FOC motor noise is minimal but then I don’t know how loud your transmission system is.
I’m also curious on where you plan to put the battery with the final revision?
I wish you the best of luck! I live this project in every aspect!
Just my opinion but I would try to mount the treads design on the back of the board directly or center like one wheel, and try to incorporate some mechanical actuator like a riding lawn mower deck that can raise it when you want to go down hill under gravity power. One problem I see in the center one wheel design, how do you keep it from packing with snow and causing drag?
Have you looked at doing spring loaded paddles? When the motor is off they would colapse and the board could be ridden normally
We have 2 other prototype designs this is type 007
008 is switch blade design (We might skip this… afraid snow may jam) This was my concept for the product designer.
009 is improved 007 design with 20+ less parts, 20% less mass, smaller diameter, same surface area.
The stators… 1600w vs 3500w
Backpack to hold controller and batteries.
Quick release… If its steep I want to rip it without the traverse. (place in pack)
Thank you for this thread…fascinating reading and I wish you much success!
Being a battery guy and seeing my share of failures, I was wondering what you were considering using for a firewall between the pack and the rider’s back?
We’re you also considering using some sort of method to quickly drop the backpack in case of a fire? Or will the pack be in some sort of fireproof enclosure that would vent all the flames/gases/smoke up and to the rear?
@malJohann Morpheus build was a battery in a backpack. obviously you fall much more in snowboarding but if you use nese modules and/or protect/insulate the pack i can’t see an issue tbh.
The battery will be insulated in soft case located in the lower compartment.
It will be pretty easy to dump the pack in an emergency.
We will consider any safety options to prevent injury.
Yea, I agree that the odds of something bad happening are low but the consequences if it does happen are quite bad. Having what will look like rocket engines strapped to ones back, in case of a failure, can very quickly cause severe burns.
Vapers have had horrendous injuries from batteries that failed in their front pockets (from loose change short-circuiting the battery). Those injuries happen very quickly, before they can pull the battery from their pocket or pull down their pants.
Cells can have internal faults, even good systems like NESE can have issues after being bounced/banged around for a while, and ESC’s and BMS’ can fail.
Not trying to be alarmist, and each of us gets to choose what risks we want to take, but I would sure not want to put a pack on my back without at least some kind of firewall. Perhaps I’ve been influenced by seeing too many failures and the horrifying injuries some have to deal with.
Heck, the firewall can even just be a piece of 3/8” thick plywood or a plastic kitchen cutting board. Anything that would give me a few seconds extra to dump the backpack.
@Battery_Mooch the backcountry pack has some built-in back support already.
(Acting as a firewall) 2 buckles to release and its off or yank the pack out by the wires.
We plan on building 5 demo mules for users to try for feedback towards final design.
I planned on having them ready first dump. This ESC issue has been a major setback.
Time to make some spring loaded battery packs, either automatically or with a rope you pull the packs are yeeted far from you in a fraction of a second
