Tour de France Team Coach Explains 'Bra Cheating' Tactic, Pushing UCI to Revise Anti-Cheating Rules

First coined in French as "triche aux soutiens-gorge", "bra cheating" has emerged as one of the most controversial new cheating scandals in professional cycling, after a veteran Tour de France men’s and women’s team coach shared exclusive, verified details of the practice with French sports outlet L’Équipe earlier this week. For more than a decade, the Union Cycliste Internationale (UCI), global cycling’s governing body, has invested millions in cracking down on mechanical doping, a longstanding fraud tactic where riders hide small electric motors inside bike frames, wheel hubs or seat posts to gain an unfair performance edge. However, the newly exposed bra cheating tactic takes this deception to a far more covert level, as bad actors now hide ultra-compact, 150-gram lightweight motors inside the padded lining of sports bras worn by riders, mostly competing in women’s Tour de France events, with a small number of male riders also using tight compression undergarments to hide identical devices.
The anonymous coach, who has worked on 7 separate Tour de France teams over 18 years, explained that the miniature motors typically deliver between 20 and 35 watts of extra continuous power, a seemingly small margin that can cut a rider’s energy expenditure by 15% during steep mountain climbs or final sprint finishes, where Tour de France stage winners are often separated by less than a single second. The thin, fabric-covered wires connecting the motor to a small, 2-hour battery pack sewn into the waistband of cycling shorts are almost impossible to spot during standard pre-race visual checks, and existing detection protocols, which use magnetic scanners to examine only bike frames and components, never pick up the devices hidden in wearable clothing.
The coach added that at least three riders in the 2023 women’s Tour de France raised red flags among race officials for sudden, unexplained bursts of speed on final alpine climbs, but no disciplinary action was taken at the time because there were no existing rules allowing inspections of riders’ undergarments. In response to the revelations, the UCI announced on Thursday that it will update its 2024 Tour de France detection protocols immediately, adding handheld metal detectors and low-radiation, body-safe X-ray scanners specifically for checking riders’ clothing and wearable gear. The body also confirmed that all undergarment inspections will be conducted by same-sex officials in private screening areas to protect rider privacy, and anyone found using hidden wearable motors will face a minimum 10-year ban from professional competition and a fine of up to €200,000.

As a lifelong Tour de France fan who’s watched every stage for 12 years, I’m absolutely disgusted that cheating has gotten this insidious. It’s infuriating to think that riders who wake up at 5 a.m. to train 6+ hours a day for years could lose out to people hiding motors in their underwear. I’m glad the UCI is finally updating its rules, but they need to be way more proactive instead of just reacting every time a new cheating tactic gets leaked to the press.
I’m a female elite amateur cyclist training to qualify for the 2025 women’s Tour de France, and I’m really torn about this news. On one hand, I hate that a small number of bad actors are ruining the integrity of women’s cycling, which is already fighting for equal funding and respect. On the other hand, I’m really worried about how these new clothing scans will be implemented. The UCI needs to stick to its promise of same-sex inspectors and private, respectful screenings, otherwise this is just another unfair barrier for women in the sport.
As a sports policy researcher who focuses on anti-doping regulations, this bra cheating scandal exposes a huge, long-ignored gap in how we regulate athlete equipment. For decades, governing bodies have only focused on checking competition gear like bikes and shoes, but as wearable technology gets smaller and more powerful, we’re going to see more and more cheating tactics that use items athletes wear on their bodies. The UCI can’t just keep patching its rules one scandal at a time; it needs to build a long-term, adaptive regulatory framework that accounts for wearable tech fraud across all cycling disciplines.
