SPEEDBOARD - $23k on Kickstarter in one day

The ride height is already adjustable, but there’s a limit to how high the deck can be while maintaining stability. The enclosure on the deck can be very thin, basically just another single layer of cells to increase capacity by 50%.

That said, if enough people want a significantly higher battery capacity inside the deck, I can create that as an option. What would your ideal capacity be, and are you willing to actually buy a speedboard like that?

I would say that I’d be happy with 1000wh without feeling the need to upgrade it. Anything more would be a welcoming bonus. This would be the board I’d take on long offroad adventures with and anything less than that just doesn’t quite cut it. If it’s fitted with some 80xx motor at 12/13s and 100-150 amps, I don’t see the need to upgrade it at all and I would absolutely buy it complete. If you are actually planning to do something like that, lemme know and I’ll redirect the funds for my trampa build to you instead. :slightly_smiling_face:

I’m looking at 900 Wh now, definitely possible to go higher. I’ve got a 80100 130 kV motor coming from Flipsky, and a 200A Maytech VESC that I’ll be testing in the next prototype. I’d suggest holding off on that Trampa purchase. I’ve ridden up a mountain with the current prototype, 6380 motor, OG FOCBOX, 396 Wh, the upgraded one with the 80100 should be a beast. 260% more torque…

I’m pretty heavy on my stuff and I’m kind of heavy too :joy: My last mountain board with dual 6374s were overheating like a motherf. I’m talking 8 miles with 3000 feet of elevation gain, that poor little 6380 would not enjoy life. But now you’ve got me excited, I would love to get a hold of the upgraded version!

edit: I’m gonna hold you to it and hold off on my trampa build. I got rid of my last mountain board because it had a 10s6p and it was not getting me as far as I wanted to go. I was going to do a 12s8p build but I’m gonna see what you whip out first :ok_hand:

Yes! Good call. What cells were you using in the 10s6p pack, and what were you planning on using in the 12s8p pack?

HG2s in the 10s6 and was going to do 30Q for the 12s8 with the eboosted double stack enclosure on the holypro. Left room for a potential top mount too if I wanted it. That was the plan anyway :woman_shrugging:t4:

I like the turning mechanism, but honestly that’s a pretty big turning radius in my opinion.

You’ve got to be able to 180 in a single lane, especially if you’re leaning 50 degrees to do it.

Have you made any versions with front and rear turning, or is that a front only mechanism?

Also, I’ll chip into some of the relevant discussion.
As everyone is submitting their wish lists, I would encourage you to ignore a lot of it for now and focus on producing only ONE SKU, being the best at what its best at.

I’ve seen lots of companies come in, get overwhelmed, and then sink, especially from the crowdfund scene.
Leave a focus on customization for a later date, and a later model. The best way to accommodate customization right now is to use standard components where you can. That also helps you avoid getting invested too deeply in any custom parts/tooling.

Don’t think the drive mech would work well with a pivoting wheel. 180 in a lane is pretty aggressive turning, any board built for speed would have a hard time doing it.

Well 50* is some pretty aggressive lean. Most people aren’t used to using more than 20* or so, and they’ll get about the same radius as that, or smaller.

And with a 30mph max, shouldn’t have to make a whole lot of compromises for stability.

It would still be interesting to see how it rode, even if it was only gravity powered to try it out.

Gonna be honest here I can’t think of many longboards that can do this at all

Might be exaggerating a bit much there. But let me put this in a different perspective.

If you’re leaning 50 degrees, and getting that big of a turning radius, you’re riding probably somewhere around the equivalent of 20* front and a 0* rear. Step on that and I promise you’ll be wanting more turn out of it, especially when you’re just getting used to it.

Also, I didn’t intend to make this much of a deal out of it. By explaining this much I’m overstating the problem. I think it would be nice to have more turn and a smaller radius than it appears to have.

It’ll do a 180 on a two-lane bike lane, radius 8’. And go around a 90° corner on a 4’ wide sidewalk. This is tighter than the turning radius of most of the people I ride with with boards tuned for 30 mph. I’m able to follow OneWheels around all but the most ridiculously acute angle turns.

I do agree with you here, 100%. My objective is to have one base SKU with optional accessories that attach to it. The battery packs will be standardized, I’ll be able to add more for different levels.

I’ll do some math on that in the next day or two, see how it compares to what I have in mind.

Cool! If ya want a prototype tester, I’m just a bit south of you :joy:

this is the post i was looking at when I hit reply I thought

what do you think about 2WD with hub motors?

maybe as a option for DIYers working with this proposed no powertrain kit

4 Likes

New motors have arrived.

  • Flipsky 80100 130 kV, 148A, 17 Nm
  • Maytech 6396 170 kV, 80A, 5 Nm
  • TorqueBoards 6380 170 kV, 80A, 5 Nm (used on old prototypes, for comparison)

Taking the kV difference into account, the 80100 motor should have 260% more torque than the current prototype.

Oh boy! Now we’re talking! You gotta let me try this when it’s set up :joy:

I had a feeling you’d like that! Definitely Trampa-competitive. Will definitely let you take it for a spin when the next prototype is done.

It’s definitely possible, and quite easy. I’ve stayed away from hub motors because they’re so heavy. I don’t have exact numbers, but as a rule they seem to weigh twice as much with half the power. Plus, the front end needs a somewhat narrow axle spacing for the steering to work. I am going to look into having a hub motor made for the front just for supplementary power and braking. Even if it ends up being 1000 watts, it would be a huge advantage to have front wheel braking available.

You’re gonna have to give us all feedback.
