I would like to make an inquiry on small rims/wheels made of aluminium or alloy. The designs must be cool designs as on cars or motorcycles. Dimensions: Diameter 150 mm including tyre, with 40 to 75 mm. And Diameter 200 including tyre, with 40 to 75 mm. Centre hole 10,8 mm They are for a hand pushed cart The cart has a weight of 7 kg and is pushed by hand, so the it moves weary slowly. And it is very simple, it is not necessary with bearings, just a centre hole. The rims is attached to the shaft just with a shim witch squeezes the shaft a little.
