No evidence of "mechanical doping" in professional cycling hasn't stopped the Union Cycliste Internationale (UCI) from checking bikes during the Tour de France.
"For years we've been taking this seriously by checking bikes at races," a UCI spokesperson said in a statement to Cyclingnews. "We've heard the rumors. The main fact is that we know you can buy such bikes on the market and restoring credibility in the sport is important."
In addition to public grumbling from fans, the use of motors on regular pedal bikes has increased in recent years - and that has certainly caught the UCI's attention: "We know that the technology is available on the market. We've been making checks as we don't want this to enter professional cycling."
