It started with a thermal camera.
A 53-year-old amateur racer in Italy crossed the line third in a small local race. Organisers had been tipped off. As the rider rolled to a stop they pointed the camera at his bike. His seat tube glowed like a toaster. Inside the frame, a motor.
That tells you most of what you need to know about mechanical doping in cycling.

Hidden motors in bikes are real. They have been caught at a World Championships. They have been caught at local Italian masters races. They have triggered a literal car chase down a French country road, with race officials banging on the boot of a getaway van trying to inspect a bike. The story is stranger than the cycling press lets on, and older than most fans realise.
Here is what we know.
The Bit Nobody Tells You About Motor Doping
Most cycling fans assume motor doping is a Tour de France problem. A Cancellara whisper. A Froome accusation on Reddit. A late-race bike change that "looks suspicious" on YouTube.
It is not.
The confirmed cases — almost without exception — are at amateur and masters level. The first was at a World Championships. The second was a local race in Italy. The third was a 43-year-old French amateur who tried to drive away with his bike rather than let officials open the frame. By 2019 a peloton at an Italian criterium had effectively mutinied at the finish line, demanding two suspect riders submit their bikes for inspection. Those two riders jumped in a van and fled.
That order matters. Mechanical doping is, on the evidence we actually have, a story of weak enforcement at the level where most racing happens. The bikes inside the World Tour bunch get scanned. The bike at your local Sunday fondo does not.
This is the part the headlines miss.
The Hungarian, the Two Million Dollar Bike, and the Decade of Silence
Stefano Varjas is a Hungarian engineer who claims to have built and sold the first truly hidden cycling motor in 1998. The deal, by his own account on 60 Minutes, was a payment of nearly two million dollars on the condition that he would not build another for ten years.
If he is telling the truth, that motor was being used through the peak EPO era. While the cycling world was fixated on syringes and blood bags, somebody was riding away from the bunch with a battery in the seat tube. Varjas has never named the buyer.
The most direct voice on the wider issue has been Greg LeMond. The three-time Tour winner has gone on record saying he does not trust certain results from the past decade until cycling figures out how to detect and eliminate hidden motors. The rest of the sport has been considerably less direct. When one of the great American cyclists tells you he is not sure what he is seeing on TV anymore, that is worth a few seconds of attention.
The Case That Actually Blew It Open
Femke Van den Driessche.
January 2016. UCI World Cyclocross Championships. Zolder, Belgium. A 19-year-old in the under-23 women's race had a mechanical and pulled out. Officials walked over to her spare bike. They opened the frame. They found a motor.
She got a six-year ban. The UCI president called it technological fraud of the worst sort. One journalist at the time called it the worst scandal cycling had seen since Lance Armstrong.
Two things mattered about that case. The first was the proof. After years of whispers about Cancellara and others, somebody had finally been caught on the record. The second was the implication. If a teenager could fit a motor in a cyclocross bike at a World Championships, the technology was clearly out of the lab and into the wild. The UCI ramped up scanning the same year.
What it did not do was stop the problem moving down the food chain.
How the Amateur Scene Got Caught
The years since Femke's case have produced a steady drip of amateur and masters scandals.
The Italian masters case in 2017 was caught with the thermal camera. A short-lived clip of a 53-year-old's seat tube glowing on the FLIR display did more to expose the technology than any UCI press release. The rider admitted on the spot.
A few months later in France, a 43-year-old amateur named Cyril Fontana was caught after winning around 500 euros in prize money over a month of racing. Christophe Bassons — a former pro and one of the few clean voices from the EPO era — got a tip and set up a sting. Fontana punctured at a crucial point in the race, abandoned, and tried to drive away with the bike. Bassons and the officials chased him. By car. They caught him.
When they opened the frame, there was a motor. Fontana's defence was that he had a herniated disc and used the motor "to feel good again." He insisted he did not actually want to win. He just did not want to get dropped.
He also dropped a sentence the sport has been chewing on ever since. I am not the only one doing this.
He got a five-year ban and 60 hours of community service after a court convicted him of sporting fraud — the court did what the federation could not.
By 2019 it was happening at criterium level. Two riders at a series in Veneto refused inspection at the finish, then jumped in a van and drove off as other cyclists banged on the side. Police were called. They got away in the chaos.
You cannot make this up. A getaway van. At a local bike race.
The pattern in every one of those cases is the same. The riders who exposed the cheats were the other amateurs. Not the UCI. Not the federation. Other riders, on other bikes, who knew what was happening and refused to let suspicious results stand.
That is the bit worth remembering.
How a Hidden Motor Actually Works
Let me break this down so it makes sense.
The most common version is a small electric motor that fits inside the seat tube, just above the bottom bracket. A bevel gear engages the crankshaft. A battery the size of a small multi-tool powers it. The whole system, including the battery, weighs around 1.5 to 2 kg. That is the entire kit.
Activation is usually a button hidden under the handlebar tape, near the shifters, or built into a fake bar-end plug. Press it once, the motor engages. Press it again, it stops. Varjas has demonstrated a more advanced version that activates automatically when the rider's heart rate hits a preset threshold — 175 beats per minute, motor on, here is your extra 200 watts at the moment you need them most.
Two hundred watts.
Two hundred watts for twenty minutes is the difference between getting dropped in a Cat 4 race and sitting at the front of a Tour de France stage. It is enormous. It is also, when the motor is off, undetectable by feel. The systems freewheel cleanly. There is no drag.
The seat-tube kit retails — quietly, on certain corners of the internet — for between three and five thousand dollars. Not cheap. Also not unreachable for a determined masters racer. The high-end electromagnetic wheel systems Varjas claims to have developed cost in the order of one to two hundred thousand. A different order of cheating, and almost nobody can afford it.
The most aggressive UCI scanning at the Tour has used handheld magnetic tablets, X-ray rigs, and thermal cameras. They have scanned thousands of bikes since 2016. Officially, no World Tour rider has tested positive for a motor during a race. Whether the bunch is clean, or the cheats have moved faster than the scanners, is the question that keeps the UCI tech team awake at night.
The Pro Peloton Question Nobody Will Answer Cleanly
Officially, the World Tour is clean.
Unofficially, you cannot have an honest conversation with a former pro about late-race bike changes without somebody raising an eyebrow. LeMond has said it on the record. Jean-Pierre Verdy, the former French anti-doping director, told 60 Minutes that by 2015 "everyone in the bunch" was starting to complain that something did not add up.
A 2016 covert investigation by an Italian newspaper and French television used hidden thermal cameras at two pro Italian races. They reported seven bikes with heat signatures consistent with motors — five in the seat tube area, two in the rear hub. The story aired, rocked the sport for a few days, then everybody seemed to move on.
Whether that was definitive proof or a noisy false positive nobody has ever been able to confirm. The cost the press underrates is the suspicion itself. Every dominant solo win invites a Reddit thread. Every late-race bike change invites a thermal-camera screenshot. The honest racer pays the price for the dishonest one — and at the moment, we have no way of telling which is which without a scanner at every finish line.
That is the fixable part.
What This Means for the Rest of Us
You are not racing the Tour. Neither am I. But you are riding fondos, club races, masters events, gravel grinders — the part of the sport where confirmed cases of motor doping have actually happened. The local scene is the weak link.
A few practical takeaways from the episode.
1. Pay attention to your local results. The Fontana case was exposed because other amateurs noticed something off. They knew his form, they knew the courses, they knew the times being put down were not consistent with the rider in front of them. That kind of community knowledge is the strongest detection tool we have at amateur level. If something looks wrong, it usually is.
2. Support events that scan. A handful of European fondos and masters championships have started running thermal scans at the finish. They are not universal yet. They should be. Race entries at events that take this seriously are entries that protect everybody else.
3. The shame is real even when the wins are not. A masters podium taken with a motor is a podium that gets stripped, written about, and remembered. The humiliation of being chased down a French road by officials is not a price worth a season's prize money.
The temptation to cheat with a motor is, in a perverse way, the most understandable doping story cycling has produced. The fountain of youth in motor form. A 50-year-old hanging with a 30-year-old on the climbs again. The appeal is obvious. The outcome is also obvious — every confirmed cheat, without exception, has been caught and named.
The sport's defence is not technological. It is cultural. The clean riders are the ones who refuse to let suspicious results stand. The bunch at that 2019 Italian criterium did more to deter motor doping in their region than any UCI press release.
The Roadman Take
The Greg LeMond conversations — the LeMond interview companion piece and the original doping conversation — are the natural follow-up to this one. LeMond has been the most direct, named voice on motor doping in modern cycling. He has paid for that directness. He has also been right more often than the people who told him to keep quiet.
The full motor doping episode is on the podcast and on YouTube.
Cycling is hard. It is supposed to be. The whole point of this sport is the cost of the win. A hidden motor is the cleanest possible expression of cheating — no biological excuse, no ambiguous threshold value, no plausible deniability. Just a button on a handlebar. That is what makes it the most embarrassing version of cheating cycling has ever produced.
And it is fixable. Better scanners. More events that use them. Riders who refuse to let suspicious results stand. The technology exists to catch every cheat in this category. What we need is the cultural and operational discipline to use it everywhere — not just at the Tour.
The clean riders are not done yet.
