really cool idea. But for us eboarders, motors act as brakes. Now… Create hub motors on with these, and you might hae something. Honestly, if you plan on going high speeds, trusting the motor to stop you isn’t the safest in the long run. Mechanical braking would be better safer, but again, it would be tricky to use these with an electric skateboard, unless you create hub motors for these. You would probably also need to create (or at least write your own firmware for) a speed controller. Pulling the brake would have to not engage the motor and instead, engage the disk brake. So the disc brake would probably need some other tiny motor to activate the brakes, controlled by the speed controller. Would be awesome, but again, would likely need to be something done by you @Brakeboard.
Now, if you could invest into the electric skateboard aspects, I bet you could utilize most of your 17 years of research and design into an electric skateboard speed controller/disc braking system that engages the disc brake, instead of the motor to slow you down. But you would have to do a lot more to make this usable for electric skateboards.
I think if you did invest into making these usable on electric skateboards, you could completely change electric skateboards as we know them. There’s a reason electric cars don’t rely on motors to stop the car, and part of it has to do with safety.
In the end, I do envision a time in the not so distance future where the dmv’s of the world create a category of e-boards that require registration, but are capable of high speeds (45 mph+), and dealing with shitty road conditions at those speeds. Yes, some have already done that, but would you trust them on shitty roads like you do a motorcycle or moped? I know I don’t, and would only ride current eboards at those speeds on perfect roads.
