i've used the Vedder ESC (VESC) that is mentioned in this article for robotics applications. It's fantastic, and the creator/designer is a great guy who is open to helping out tinkerers. It's one of the cheapest off-the-shelf ways to move a bigger hobbyist motor with encoder support that I've found. Nothing but love for it.
A year ago i've launched a directory where anyone can share their DIY eboard :) http://esk8builds.com
If I'm going 50km/h on something, I would at least like it to have proper disk brakes like mid-range and higher bicycles do. Going at those speeds may be fun and all, but you're 1 careless driver away from the hospital, unless you ride on abandoned roads.
Instant flying lesson.

A longboard downhill can easily go over that speed.
I hit that speed regularly on mild downhills. Bombing a hill you can hit 80km/h pretty easily. I think the record is around 140km. Certainly not bragging, as it's not that impressive among downhill longboarders. Just trying to give some perspective.

But then you get speed wobbles... https://imgur.com/auUscXX
As hug mentioned, shifting weight helps. Also as you begin to catch wobbles, you can relax your stance a little bit to counteract them - but that takes practice. Finally, you simply control your speed - usually by sliding, but I can imagine on an e-board slides will be very cumbersome.
Of course if you know all of this, you probably already have realized that e-boards are barely good for anything but cruising from point A to B, and there's infinitely more breadth and depth to this sport than just that.

Tired of writing, the main things I wanted to point out are that electric board drivers look like assholes and eletric skateboards are retarded. It's as simple as that. Stop using these things and learn to skate

Sure, you can easily wear a GPS watch while longboarding.
Yeah I wasn’t asking hypothetically. I wanted to know what they actually used to record their speed.
Lifelong skater here. Learn to actually skate. Electric board riders look like dufuses. Seen quite a few in NYC. Their stances are always way off and unbalanced, seen many who couldn't stop manually, and it goes against/disallows for most of the reasons for having a skateboard. You can't get true ground/board feel while carving, its weight and form prevents execution of flip tricks, it takes away trial and error lear…

Yeah, lack of brakes on a 50 km/h vehicle is a problem. And in the case of skateboards, lack of handlebars too. That said, disks aren't essential for good bicycle stopping performance. Good rim brakes (like most mid or high end road bicycles) stop just as quickly as disk brakes in dry conditions . Rim brakes are not really an option for long boards, though.
lack of brakes Sliding/skidding (where the board is manoeuvred in the direction perpendicular to the movement) will make you loose speed pretty quickly. Apart from that motor can be used to brake. Not sure what exactly is needed for it, but a DIY board I rode once had a dual trigger on the remote, one direction for moving forward, the other one for braking. Pretty convenient though won't stop you as quick as some fri…
Yeah, but it has the disadvantage of wearing out the wheel surface and requiring some technique. Any asshole can pretty a brake lever, and brake pads are cheaper than wheels.
> Apart from that motor can be used to brake.
It can be iff the controller is configured to. I thought I saw another comment mentioning this article's device is only rigged to go forward. I agree with you that an electric motor might be a sufficient brake for this application (at least, better than nothing).
> Pretty convenient though won't stop you as quick as some friction brake.
Yeah, it's hard to beat the mechanical simplicity.
> [lack of handlebars] is only a problem if you either don't know how to steer with the board, or are trying to take sharp turns at too high speed
I was talking about braking performance, actually. Handlebars help you throw your weight back and keep it in the right place for rapid braking.
