I’m really curious about this chinese electric skateboard, I already have on DIY tho, single drive 9mm belt. So quite a lack in torque and braking. http://www.bisekcycle.com/index.php?route=product/product&product_id=116
I send him an email for more details, and this is what he responded :
It’s 61 KV motor. The transmission is 1:1, no gear inside.
The motor is fixed to axle by screws.
The motor cannot go faster than 30 km/h because we set limitation on controller. If exceed the speed, the controller and motor will get very hot and unstable.
By the way, we use controller instead of ESC. The controller is developped specially for skateboard not that kind of ESC for RC planes. When you open the upper deck, you will see controller and battery. But we don’t suggest do any change to the chip and battery.

Are there more things that i could ask? I really like the design and style of the board. Not sure if I actually gonna spend this much money on it.
