"Downhill Racing"
- I consider this fad to be bad for cycling, and contrary to the spirit of cycling. It is effectively just a variant form of motorcycle racing, since the power is provided by the machinery that carries the rider and bike to the top of the run. Bicycling should be a human-powered activity, or it is not bicycling.
