If you release something publicly, you only have 12 months to file for a patent (in the US)
However, in many countries there is no grace period. If you want international rights, you have to apply for a patent before you ever show it off to the public
The handle looks to be in the middle between the wheels.
This makes no sense as the center of gravity is further back, with the motors being far heavier than the front wheels. Bad engineering
who would not want to carry it perfectly at the center of gravity? Making the handle this wide is thus unnecessary. With that logic you should have made the handle as wide as ther entire deck as apparently âwider is betterâ
But I get it - you also need space for your feet so you compromised and also made it look good by being symmetrical.
What if someone installed some lights up the front? Or some hub motors? Now your perfect handle design position doesnt allow the weight to be redistributed? Everyone would complain the handle was poorly designedâŚ
I like of a lot of torque and I donât know if dual-hub is good enough. I wish there would be a good way to cut the 45km/h speed in half and double the torque but canât see it with hubs.
@onloop
any information on weight, wheel-softness, motor kv and power?
I suppose if you had a set of small, Poorly designed, hub motors that all the Chinese boards all seem to have now you probably need four of them to get decent performance levels.
However if you build your hub motors from the ground up. Jam the biggest stator, best magnets and the most copper possible inside. Then Power it by an upgraded vesc that can handle high current throughput you only need two of themâŚ
Infact for lightweights you could get away with just one of the NEW R-SPEC âGHOSTâ motors.
yeah sure but my question was more directed at the fact that you would have to RETRO-fit these additional hub motors. Is anyone going to do this? is there even space in the enclosure for two additional VESCs? With the Qu4tro you already buy it as a 4WD.
