It’s a weight thing really. I’ve heard people complain that they need to change seals in forks annually yet their car doesn’t need that service. But if you ran seals as tight as those in a motor vehicle not even the fattest rider on an ebike would move them. Same with tires. It would require a lot of weight to make a tire and rim that would be unlikely to flat for DH racers. And that weight would not accelerate as well as a lighter weight bike. When you are racing time counts. A second slower from a start can be the difference between a podium and sixth place.
