Problems solved by technology
Existing bicycles have the following shortcomings: the riding speed is slow, and the driving speed of both feet is limited, resulting in a lower riding speed, generally below 20 km / h. Therefore, people often change to ride electric bicycles or motorcycles in order to pursue speed. However, the batteries of electric bicycles will cause environmental pollution, and motorcycles need to consume fuel, a non-renewable resource.
