"The fairing on a velomobile sometimes makes it more subject to cross-winds than a similar unfaired cycle. The effect of cross-winds is complicated because the force of the wind can act as a steering force, as-if the rider had tried to steer the cycle. "Wind steer" can be a safety issue and may also hurt performance, as a serpentine path is longer and thus slower than a straight line. Thus, a design with inferior aerodynamics may be better overall. For example, it is common for time-trial bicycles to use a solid disk rear wheel for best aerodynamics, and a spoked front wheel that has worse aerodynamics than a disk, but is less likely to steer the bicycle in a cross-wind." Something like a boattail that increases the length of the vehicle substantially could very well affect lateral stability from crosswinds, but I feel like the majority of mods centered on streamlining will not have a negative effect, since most of them focus on the front profile of the vehicle and decreasing the trailing wake. |
This is not a good comparison as one vehicle has a body and the other one doesn't. A "normal" recumbent bike is about 25% more aerodynamic than most uprights yet as far as I have ever noticed the wind doesn't affect the recumbent any more than the upright.
