Stary VS Inboard M1 electric skateboard

[xshana414]

Which one do you think is better and worth getting? I'm not looking for answers like "just make one yourself or DIY!" I'm just curious about what everyone thinks about these 2 boards since the motors are in the wheels.

I backed Stary for the affordable price at the time and mainly the lightweight. However, with that said. I wouldn't pay full price for a Stary. I ended up paying $420 or $460/each board which haven't been delivered yet.

I'm still wondering if I'll use it more then my regular board since of course our DIY boards have more range and more power.

I do feel this single motor will be lacking but will have to test to be sure.

M1 looks nice but we are definitely here because we prefer DIY so our opinions may be very biased.

Even though Stary has parts of their motor in the wheel, it is not a Direct Drive. It still uses a gear down ratio, much like the belt-drives. But instead of belts, they use planetary gears. So Stary basically still rides like belt-driven board.

M1 is a Direct Drive and have all their motors inside the wheel, well at least the pre-production ones. Whatever the motors put out, the wheels will put out also; and vice-versa. This is very evident while coasting.

Is M1 better than Stary? I dunno, they are both not out yet. But I do know the answer if DD is better than Geared on E-boards.

hard to say which one is better as neither board is available yet! lol.

I would not get the Inboard M1. After i saw them using VESC in their "beta/pre-production" board with no credit to Vedder i won't support them. I don't have an issue with them using it while they "built their own ESC", but they repeatedly avoided giving Ben credit which is just not what i would support. Even now that they likely have a different ESC in use. I doubt they ever gave him even a small donation for his time. Hopefully i'm wrong.

Hello Guys!

We've already discussed this subject in this post: https://endless-sphere.com/forums/viewtopic.php?f=35&t=63540&p=1073028&hilit=theocerbo#p1073028

We used the VESC to speed up the development process. It allowed us to test different motor designs while developing our own motor controller. We do not use the VESC anymore.
Also I talked with Benjamin many times in the past, I actually introduced him to electric skateboards. Anyway if you want to hear more of the story check out the link up there and if you have any question feel free to ask

Cheers,

I'd like to hear it from Ben's mouth that you actually introduced him to electric skateboards.

If your such great friends with him as a friend you should of also promoted or even mentioned his open source VESC while using it. You know how much he greatly believes in OS.

Theocerbo - i do recall him mentioning that. I guess to clarify my issue/complaint was not that it was used in beta, but simply that you did not credit the inventor Benjamin Vedder. Even after folks asked, you simply said it was an open source controller. At least a link to his site and credit would've possibly netted me as a customer. I opted to spend my $ elsewhere as i disagreed with this omission strongly. Whether you introduced him to e-boards or not... In poor form in my opinion.

Did you donate any funds as a thank you for his hard work to give you this "development" Motor controller?

I like how they photoshop their board on to the feet of skater wearing a Boosted helmet........

 

[tung256]

the airwheel looks awful
glad guys like Marbel and Starry try to make sleek looking eboards

 

[sk8norcal]

yeah, the airwheel looks like crap, as if designed by someone who doesn't skateboard.

but they are a huge company, capable of designing something a lot better and cheaper.

they got some new personal ev's out.

Guys, need your help in fact checking: Can you make sense of this exchange I saw on Inboard's FB page?

Gongfu Xiongmao "However, when the battery is full, the current has nowhere to go and braking is disabled to avoid damaging the battery. With the M1, you'll still be able to engage the brakes with a battery that's fresh off the charger...."

My physics teacher is a hardcore e-skate builder. He said that if you can brake with a M1 "fresh off the charger" the board is converting the current to heat somewhere or putting back into the battery (electricity). Does this mean that the M1 will always be charged under capacity to leave room for braking regeneration current?

Isn't this sacrificing distance for those few clients who happen to live atop large hills?

Top speed would be lower, since a lower charge would also mean less top voltage/power too? frown

Inboard Hey Gongfu. For us addressing this was more of a safety issue than anything else... not as much for the few clients who live on top of a large hill, but those who don't but may occasionally start on top of a large hill and expect the brakes to work on a fresh battery. Without this feature they're in for a dangerous surprise. I can only say we're using the BMS to manage this extra power, and so far this is not sacrificing advertised distance or advertised top speed.

Isn't "we're using the BMS to manage this extra power" just a circular way of saying "Yes, we are putting the current back into the battery so, no it's never actually charged to full capacity". "Fresh" isn't exactly "full", and "maximum speed" isn't really "advertised top speed", is it? Their carbon deck doesn't look like it would play nice with the heat created from dynamic braking (I'm assuming they'd mention this capability if they had it)

If they don't ever reach max charging voltage, is the advertised 10 miles realistic with LiFePo4 cells?

Power: 1000 watts continuous, 1600 watts max
Battery Range: 10 miles (40v / 100 Wh / LiFePo4)
Top speed: 24 mph
Motor power: 1800 watts
"93%-95% efficiency curve"

How about 4 direct drive wheels? (Ouchies at >100 km/h)
