Quick Summary
Quick Summary
Our client was riding a rented bicycle with friends when the front wheel detached, throwing her to the pavement. The rental shop denied the wheel ever came off and argued a signed liability waiver blocked her claim. We proved the shop never had her sign a waiver, and an independent engineering inspection found impact damage on the front fork that could only occur if the wheel separated. The shop's insurer settled at mediation for far more than it had previously offered.

What happened?
What happened?
Our client rented bicycles with a group of friends for a day of riding. Partway through the ride, the front wheel of her bicycle separated from the frame. With nothing holding the front end, the fork dropped to the pavement and she was thrown from the bike, suffering injuries.

Why was this bicycle injury case difficult?
Why was this bicycle injury case difficult?
Two obstacles stood in the way. First, the rental shop claimed it was immune from liability because the group had signed a liability waiver before renting the bikes. Second, the shop's owner refused to admit the incident had even happened, insisting our client must have simply lost her balance — not that the wheel had failed.

How did we defeat the liability waiver defense?
How did we defeat the liability waiver defense?
Through written discovery and depositions, we established that the shop had not followed its own rental procedures. Only one person in the group had actually signed a waiver, and our client was not that person. A waiver signed by someone else cannot give away our client's rights, and an unsigned waiver could not bar her claim. (California courts have also long held that a liability waiver generally cannot release a business from responsibility for its own gross negligence.) The “immunity” the shop relied on simply did not apply to her.

How did we prove the wheel actually came off?
As soon as our client retained Schwinghamer Law, we sent the rental shop an evidence preservation letter — a formal demand that it sequester and preserve the bicycle. That step kept the key evidence from being altered or lost. Over the shop's objection, we then compelled an inspection of the bicycle by an independent engineering expert. The engineer found fresh score marks and impact damage on the front fork — damage that could only have been caused by the wheel separating and the fork striking the pavement. That physical evidence directly contradicted the owner's claim that the wheel had never come off.

What was the outcome?
What was the outcome?
By the time of mediation, we had done more than prove liability. We also had evidence that the shop had tried — unsuccessfully — to hide its negligence and shift blame onto an injured customer. The shop's insurer recognized that taking this case to trial carried significant risk, and it agreed to settle at mediation for substantially more than it had ever previously offered.

Frequently Asked Questions
Frequently Asked Questions
Q: Does signing a liability waiver mean you can't sue for a bicycle injury?
A: Not necessarily. A waiver generally binds only the person who actually signed it, and it must be clear and properly presented. In California, even a valid waiver usually cannot excuse a business's gross negligence. Whether a waiver bars a claim depends on the specific facts — which is why it is worth having an experienced injury attorney review it.
Q: Who is responsible when a rented bicycle fails and causes a crash?
A: Depending on the facts, a rental shop can be liable for renting a defective or poorly maintained bicycle, and a manufacturer can be liable if a product defect caused the failure. Proving it often requires preserving the bicycle quickly and having it examined by a qualified engineer.
Q: What is an evidence preservation letter?
A: It is a formal letter demanding that a person or business preserve specific evidence — here, the bicycle — so it cannot be repaired, altered, or discarded. Sending one early can be critical, because lost evidence can turn a strong case into a difficult one.
Q: How long do I have to file a bicycle accident claim in California?
A: For most personal injury claims, California allows two years from the date of injury (California Code of Civil Procedure section 335.1). Some claims have much shorter deadlines — for example, claims against a government entity generally must be presented within six months. Because deadlines vary, speak with an attorney as soon as possible.
