Trek Recalls 700 Electric Bicycles Over Dangerous Chainring Defect

Defective Bolts on 2026 Trek E-Bikes Pose Crash Risk — Legal Options for Victims of Serious Falls or Injuries

Trek Bicycle Corporation has issued a nationwide recall of approximately 700 electric bicycles from its 2026 model year lineup after discovering a serious defect that could lead to sudden falls or crashes. The issue stems from improperly secured chainring bolts, which can loosen over time, causing the chainring to detach from the crank. This failure may result in complete loss of control while riding.

The recall affects four high-end models: the Domane+ ALR 5, Domane+ ALR 6 AXS, Checkpoint+ SL 6, and Checkpoint+ SL 7 electric bicycles. These bikes, which retail for between $5,000 and $8,000, were sold through authorized Trek retailers and online platforms from July 2025 through September 2025. While no injuries have been reported so far, the defect has already caused at least three incidents where the chainring separated from the bicycle.

Consumers are being advised to stop using these bikes immediately and bring them to authorized dealers for a free repair. Trek is also offering a $20 in-store credit as part of the remedy. However, the risk of a high-speed crash and the high value of these electric bicycles raise serious questions about Trek’s safety protocols — and what legal options may be available to riders who were injured.

Understanding the Chainring Defect: What Is the Hazard?

The chainring is a key component of a bicycle’s drivetrain. It connects the crankset to the chain and enables the rider to transfer pedaling power to the rear wheel. On electric bicycles — especially high-powered models like Trek’s — the chainring must withstand more torque and stress than on traditional bikes.

Trek’s recall stems from bolts in the chainring assembly that may loosen over time, especially under riding conditions. If these bolts back out completely, the chainring can detach mid-ride, rendering the drivetrain useless and potentially causing the rider to fall, crash, or be ejected from the bike.

This type of mechanical failure is particularly hazardous for electric bikes due to:

• Higher average speeds: Many riders reach 20–28 mph with motor assist.
• Heavier bike frames: E-bikes are heavier than standard bicycles, increasing crash force.
• Longer ride durations: More stress builds over time, especially on longer commutes or trails.

The defect is not cosmetic or theoretical — it directly compromises rider safety and has already caused multiple malfunctions.

Which Trek E-Bike Models Are Recalled?

The recall applies to the following Model Year 2026 Trek-branded electric bicycles:

1. Domane+ ALR 5
2. Domane+ ALR 6 AXS
3. Checkpoint+ SL 6
4. Checkpoint+ SL 7

Each of these bikes includes the word “TREK” printed on the downtube and a model name printed on the top tube. They come in various sizes and colors and were sold through independent bike shops, authorized Trek retailers, and onlinenationwide.

Sales occurred from July 2025 through September 2025, with retail prices ranging from $5,000 to $8,000 per unit. These are premium electric bicycles often used for long-distance road cycling, endurance riding, or gravel biking.

Why This Recall Matters — Even if No Injuries Were Reported Yet

While Trek reports no injuries as of the December 11, 2025, recall announcement, the danger is real. In three separate incidents, riders experienced sudden drivetrain failure mid-ride due to chainring detachment. These failures could easily have resulted in traumatic injuries such as:

• Broken bones or fractures
• Head trauma or concussions
• Internal injuries from high-speed impact
• Spinal injuries from ejection over handlebars

Not every injury is reported to the manufacturer, and some victims may not immediately associate the failure with a known defect. In many cases, riders who crashed might have assumed it was rider error, tire malfunction, or road conditions — not a defective drivetrain.

If a rider has already suffered an accident involving a sudden loss of pedal power or drivetrain failure, this recall should prompt a closer legal and medical review.

Trek’s Response: Repair Program and $20 Credit

Trek is offering consumers a free repair for recalled models. Authorized Trek dealers will inspect the bikes and tighten the chainring bolts to the proper torque specification.

In addition, the company is providing a $20 in-store credit toward Trek, Electra, or Bontrager merchandise. This credit must be redeemed by December 31, 2026.

While this remedy may seem reasonable on the surface, critics argue that:

• A $20 credit is insufficient compensation for a potentially dangerous crash risk.
• The failure should have been caught during quality assurance testing, especially given the premium price point.
• Some riders may have already sustained unreported injuries or damaged property due to the defect.

For injured individuals, a product liability claim may offer a more appropriate path toward meaningful compensation.

Legal Rights of Riders Injured by Defective E-Bikes

Victims injured due to a mechanical failure like this one may be eligible to file a product liability lawsuit against the manufacturer or other parties in the distribution chain. Such claims may be based on:

• Defective design: If the chainring or bolt system was inherently unsafe.
• Manufacturing defect: If certain bikes left the factory with improperly torqued bolts.
• Failure to warn: If Trek did not notify riders quickly enough about the risk.
• Negligence: If quality control protocols were not followed.

Successful claims may lead to compensation for:

• Emergency room and medical expenses
• Surgery, physical therapy, or long-term care
• Lost wages or diminished earning ability
• Pain and suffering
• Emotional distress
• Damage to the bicycle or other property
• Punitive damages, in extreme cases

Who May Be Eligible to File a Claim?

You may have a legal claim if:

• You own one of the recalled Trek electric bicycles.
• You were riding a Trek e-bike and experienced sudden drivetrain failure.
• You suffered an injury that may be tied to a chainring or crankset malfunction.
• You paid for repairs or replacements due to the defect.
• You were a passenger or pedestrian injured due to a bike crash involving one of these models.

Even if you’re not sure whether your injury was caused by this defect, legal consultation can help you understand your options. In some cases, product failures are revealed after the fact, and injury victims may qualify for compensation based on subsequent recalls.

Where Were These Bikes Sold and Manufactured?

The recalled bikes were sold across the United States by:

• Independent bicycle shops
• Trek-authorized retailers
• Trek’s official website and online store

The importer is Trek Bicycle Corporation based in Waterloo, Wisconsin, but the affected bikes were manufactured in Cambodia. This international supply chain could play a role in potential legal claims, depending on where the defect originated.

What Riders Should Do Right Now

If you purchased a Trek electric bicycle between July 2025 and September 2025, or if you’re unsure whether your model is affected, take the following steps:

1. Stop using the bicycle immediately to avoid further risk.
2. Check the model and serial number against Trek’s official recall website.
3. Schedule a repair with an authorized Trek dealer — the repair is free.
4. Keep documentation of any repair, crash, medical treatment, or communication with Trek.
5. Consider contacting an attorney to investigate whether you may be eligible for financial compensation.

Which Trek e-bike models are affected by the recall?
The recall applies to Model Year 2026 Domane+ ALR 5, Domane+ ALR 6 AXS, Checkpoint+ SL 6, and Checkpoint+ SL 7 electric bicycles. All models have the “TREK” name on the downtube and were sold between July and September 2025.

What is the exact defect with these bikes?
The chainring bolts can loosen over time. If they separate completely, the chainring may detach from the crankset, causing a sudden loss of control that can lead to a fall or crash.

Has anyone been injured by this defect?
Three incidents have been reported involving the chainring coming loose, but no injuries have been officially reported yet. That said, unreported crashes or medical incidents may exist, and more may come forward as awareness grows.

What should I do if I was injured riding one of these bikes?
You should stop using the bike, document the incident, seek medical attention if needed, and contact a product liability lawyer. Injuries resulting from a manufacturing defect may qualify for compensation through a legal claim.

Can I file a lawsuit even if the bike was repaired after the recall?
Yes, if the injury occurred before the repair was completed. The recall does not prevent you from taking legal action if the product already caused you harm.
