It bothers me that ebikes are not more successful in the US. I don't think people appreciate how well they work, or how they may be a much better way for many people to get fit.
More and more, I try to ride on a nice set of paths that curve along the Virgin River. It's interesting, trying to push the bike as far as it will go. You could probably race ebikes, but it would be tough to come up with a set of rules and, in particular, a course. You would need to figure out how much power a bike could have, and how much power a rider would need to supply. You would need a course with hills and curves, maybe some other challenges.
Like other forms of racing, the idea would be to create a laboratory of performance. How good is this motor versus another? This drivetrain? This suspension? Force people to push envelopes. It's not a competition with non-powered bikes. It's simply a way to test ideas and train people to master a complex machine. It also would try to define the ebike in a different way.
Plus, all people seem to care about any more is sports
