对于每项任务都假定，同样的辐条车轮将总是装在前面，而装在后面的车轮是可以选择的。

For each of the tasks assume that the same spoked wheel will always be used on the front but there is a choice of wheels for the rear.

两种基本的车轮类型是分别用金属辐条和实体圆盘组装而成（见图1）。辐条车轮较轻，但实体车轮更符合空气动力学原理。

The two basic types of wheels are those constructed using wire spokes and those constructed of a solid disk (see Figure 1) The spoked wheels are lighter, but the solid wheels are more aerodynamic.

这些旋转电机形似自行车车轮(见下图)，辐条换成了黑色电活性聚合物薄片。

These rotary motors (see picture) resemble bicycle wheels that have had their spokes replaced with thin, black slivers of EAP.
