5 Common Bicycle Crash Injuries and What to Watch For

Bicycle accidents often lead to serious injuries, many of which aren’t immediately obvious at the scene. Understanding what to look for after a crash can help ensure you get proper medical treatment before a minor issue becomes something much worse.

Through our work with injured cyclists, we’ve seen how quickly a routine ride can turn into a personal injury case involving head trauma, spinal injuries, or broken bones. Knowing the most common injuries that follow a bicycle crash and how those bicycle accident injuries typically show up can help you take the right steps toward recovery.

A bicycle helmet offers important protection, but it’s not a guarantee against harm, especially when motor vehicles are involved.

Head Injuries: Why Cyclists Can’t Afford to Ignore Them

When it comes to bicycle accidents, head injuries are the most dangerous and the most unpredictable. Whether your head hits the pavement or a passing vehicle, even a seemingly minor impact can lead to serious consequences.

Traumatic Brain Injuries and Concussions

Traumatic brain injuries (TBIs) are among the most severe injuries cyclists face. These injuries occur when the brain jolts or shifts inside the skull during impact—and they don’t always show symptoms right away.

Keep an eye out for these warning signs:

• Headaches that keep getting worse
• Difficulty concentrating or feeling mentally “foggy”
• Memory problems or confusion
• Nausea or repeated vomiting
• Mood swings or irritability
• Light or sound sensitivity
• Trouble sleeping

Concussions are especially tricky. You might not lose consciousness, but that doesn’t mean your brain wasn’t affected. If you’ve been involved in a bicycle crash, especially one involving motor vehicles, don’t assume you’re fine. Get checked out.

Skull Fractures and Facial Trauma

Even with a helmet, a high-impact bike accident can cause a skull fracture. These are serious injuries that require emergency medical care.

Red flags to look for include:

• Intense headache
• Bleeding from the ears or nose
• Swelling or bruising around the eyes
• Clear fluid leaking from the nose or ears
• Loss of consciousness

Facial injuries are also common. When you’re thrown forward off a bicycle, your face often takes the first hit. That can mean broken bones, deep abrasions, or injuries that may need reconstructive surgery.

Spinal Injuries: Lasting Damage That’s Often Invisible at First

A bicyclist involved in a crash, especially one with a motor vehicle, is at real risk for spinal cord damage. These injuries can be devastating and often come with lifelong consequences.

Understanding Spinal Cord Damage

The spinal cord is like your body’s main communication line. When it’s injured, the brain can’t send clear signals to the rest of your body.

Bicycle accidents can cause:

• Complete spinal cord injuries: Total loss of feeling or movement below the injury
• Incomplete injuries: Some movement remains, but often with weakness or numbness
• Cervical injuries: Impact both arms and legs
• Lumbar injuries: Affect the legs and lower body function

Neck and Back Injuries

Not every spinal injury involves the cord itself—but that doesn’t make them any less painful. Herniated discs, compressed vertebrae, and soft tissue injuries are all common after a bike accident.

Watch for symptoms like:

• Severe neck or back pain
• Tingling or numbness in limbs
• Muscle weakness
• Loss of bladder or bowel control
• Breathing difficulty

Whiplash is particularly common when a cyclist is rear-ended by a car. While it may not sound serious at first, it often leads to chronic pain and months of rehabilitation.

Broken Bones and Fractures

Fractures are one of the most common outcomes we see after a serious bike accident. When a collision throws a rider off their cycle, whether from impact with a car or sudden loss of control, it’s not unusual to walk away with multiple broken bones. The body simply isn’t built to absorb that kind of impact.

In our experience, these are the most common fracture locations we come across:

Upper body fractures:

• Wrist fractures, especially scaphoid injuries, from trying to brace during a fall
• Collarbone breaks that often require plates, screws, or surgical realignment
• Arm and shoulder fractures, usually caused by the instinct to catch yourself mid-fall

Lower body fractures:

• Hip fractures, particularly serious for older cyclists and often requiring surgical intervention
• Femur breaks, which take a significant amount of force and typically involve extended rehab
• Ankle and foot fractures, often caused by pedal entanglement or impact during a rollover

Rib fractures also come up more than you’d think. At first, they might feel like soreness or a pulled muscle—but the risk is what happens underneath.

Complications from rib fractures can include:

• Punctured lungs (pneumothorax) from a sharp break
• Internal organ damage, including the liver or spleen
• Internal bleeding that’s not immediately obvious
• Breathing difficulty or sharp chest pain, especially with movement

It’s not always the big, dramatic injuries that turn serious. Sometimes, it’s the ones that get overlooked in the first few hours.

Road Rash and Soft Tissue Injuries

Road rash might not sound like a big deal, but we’ve seen cyclists come in with wounds that required skin grafts, months of wound care, and left permanent scarring. When your skin scrapes across pavement during a crash, the friction can tear through multiple layers, sometimes deep enough to require skin grafts.

Here’s how we typically categorize the severity:

First-degree road rash:

• Affects only the surface layer of skin
• Resembles a sunburn and usually heals without lasting effects

Second-degree road rash:

• Goes deeper into the dermis
• Often needs medical attention and may result in scarring

Third-degree road rash:

• Removes all layers of skin and may expose muscle or bone
• Always requires immediate medical treatment, sometimes surgery

But it’s not just skin that gets damaged. Soft tissue injuries are incredibly common in bicycle crashes and can be just as disruptive—sometimes more so.

Examples of soft tissue damage we frequently see:

• Torn muscles that need surgical repair
• Damaged tendons, which often require months of physical therapy
• Ligament injuries that affect joint strength and mobility
• Deep contusions causing swelling, bruising, and limited movement

These types of injuries may not show up on imaging right away, but they’re very real—and they often take longer to heal than a fracture.

Internal Injuries: The Hidden Dangers

Not every injury from a bicycle crash shows up on the surface. In fact, some of the most serious injuries we’ve seen are the ones you can’t spot right away—internal bleeding, damaged organs, or trauma that only shows itself hours later. That’s what makes internal injuries especially dangerous: you may feel fine, but your body could be telling a different story underneath.

Abdominal Injuries

The abdomen takes more of the impact than people realize—especially when a cyclist gets slammed into handlebars or hits something head-on. We’ve seen crashes where the spleen, liver, or intestines were torn without a single visible bruise.

If you notice any of the following after a crash, it’s time to see a doctor:

• Pain or tenderness around the stomach area
• Nausea that doesn’t go away, or vomiting
• Feeling dizzy when standing up
• Fast heartbeat with no clear reason
• Bloating or swelling in the abdomen

These symptoms might not feel urgent at first, but internal bleeding can turn serious fast.

Chest Injuries

Cyclists who land hard on the handlebars or take a hit from a vehicle sometimes walk away with chest injuries that don’t catch up to them until later. Some involve the lungs or heart, and the warning signs can be subtle.

Be especially cautious if you experience:

• Shortness of breath, even while resting
• Chest pain that worsens when inhaling
• A heartbeat that feels erratic or unusually fast
• Coughing up blood (even a little is a red flag)
• A tight feeling, like you can’t take a full breath

These could point to a punctured lung or trauma to major blood vessels—both of which need immediate care.

When to Seek Medical Attention

We can’t stress this enough: just because you’re walking doesn’t mean you’re okay. We’ve worked with plenty of cyclists who felt “shaken up” at first, only to end up in the ER 12 or 24 hours later with serious symptoms they’d brushed off. It happens more than you’d think.

So here’s a simple rule: when in doubt, get checked out.

Call for emergency care if you’ve had:

1. Loss of consciousness—brief or not
2. A headache that doesn’t go away
3. Vomiting that keeps happening
4. Weakness or numbness in your arms or legs
5. Trouble breathing or chest tightness
6. Any signs of possible internal bleeding

And even if you feel okay:

• See a doctor within a day of the crash
• Keep track of symptoms—even the small ones
• Make sure everything’s documented, especially if a legal claim becomes necessary later
• Don’t assume soreness is “just soreness”—some injuries, especially spinal or soft tissue ones, take time to show

One more thing: adrenaline can cover up pain in ways you won’t expect. Don’t let a “tough it out” mindset cost you your health.

Protecting Your Legal Rights

Medical treatment is just one part of the equation. If your crash happened because someone failed to yield, opened a car door without checking, or because of poor road conditions, you may be entitled to pursue a personal injury claim. That’s not just about compensation—it’s about protecting your future after a serious accident injury. And understanding your legal options early can make a real difference in how recovery unfolds.

At Johnson & Groninger PLLC, we help cyclists recover compensation for things like:

• Medical bills, both current and future
• Time missed from work
• Ongoing physical therapy or rehab
• Chronic pain, loss of movement, or permanent injury
• Emotional stress and the overall impact on your life

Here’s what we’ve seen too often: a cyclist accepts a fast settlement, only to realize months later they’re still in treatment—with bills piling up and no legal recourse left. Don’t let that happen.

Before you sign anything or take a call from the insurance company, reach out to someone who knows bicycle accident cases inside and out.

We offer a free case evaluation and can walk you through your options. You don’t have to navigate the legal side alone—especially when you’re already dealing with the recovery.
