Abstract
The utility model relates to an accessory of an electro-tricycle, in particular to a knife wheel aluminum alloy wheel hub of the electro-tricycle. The knife wheel aluminum alloy wheel hub of the electro-tricycle comprises an outer ring and a bearing seat. The knife wheel aluminum alloy wheel hub of the electro-tricycle is characterized in that spokes in a circular arc shape are arranged between the outer ring and the bearing seat, reinforcing ribs are arranged on the edges of the two sides of each spoke, a plurality of weight reducing holes with gradually-reduced diameters are formed in the surfaces of each spoke, and a mounting hole is formed in the center of the bearing seat. Therefore, the knife wheel aluminum alloy wheel hub of the electro-tricycle is reasonable in design, practical and convenient to use.
