Painted the wheel fork once again, front wheel ball-bearings cleaned

Also cleaned the front wheel ball-bearings. Looks like new now.

Ball-bearings from the Titanic


Rusty ball-bearing

No, this is not part of the Titanic but a C5 ball-bearing.

I was thinking about how to build in the gear hub. There would be enough space if I move the electronics box.

The plan is to drive the gear hub with one chain (red) and connect the gear hub and rear axle with another chain (green):
This certainly requires a sort of a dropout (blue) to be developed to attach the gear hub. But the main problem at present is to find a suitable sprocket which could be mounted on the gear hub.
