So it's going to ride around with just the hubs bolted to the body?
No wheels, tires or other suspension?

First you said "hub plus brake disk", now it's "the brakes" which to me implies the whole wheel side of the brake system.
So which is it?

35 to 40lb is a good estimate.
My leaf aluminum wheels weigh about 20lb each. The tires are also right at 20 each.
I have heard the OEM steel leaf wheel weights over 25lb, but haven't attempted to verify.

So it's likely 23kg per hub and disk. Not including the wheel, tire, spindle, caliper, control arm or arms, strut or shock, spring, tie rods, track bar and the wheel covers.
It looks like the wheel covers are connected to the unsprung side of the suspension and not the body, just looking at the picture on the OP.

Now I'm thinking more like 400lb of unspring weight if it's made like a car instead of building it like an expensive race motorcycle sparing no expense for exotic materials.
But these hub motors alone weigh substantially more than a motorcycle wheel, tire, hub, spindle brake assy so it can't be made anything like a bike suspension.
