Roping the Motor Dopers

A French cycling official confronts a rider suspected of doping and ends up on the hood of a van making a high-speed getaway.

This scenario played out in May at the Routes de l’Oise cycling competition near Paris, and the van allegedly carried evidence of a distinctly 21st-century cheat: a hidden electric motor.

Cyclists call it “motor doping.” At the Paris Olympics, officials will deploy electromagnetic scanners and X-ray imaging to combat it, as cyclists race for gold in and around the French capital.

The officials’ prey can be quite small: Cycling experts say just 20 or 30 watts of extra power is enough to tilt the field and clinch a race…
