Part of the issue with bikes is that the differences between bikes are really marginal in importance for most riders. The biggest variable in performance, by far, is the motor. Unless it's completely unreliable, most people will not be pushing even the cheapest bike anywhere near its maximum capability. If you're a marketer trying to get people to buy more bike equipment and higher quality than they need, you sell it by presenting people with the image of how they'd like to ride, not what they're actually going to do.
