There are several factors that make reconstructing bicycle accidents more difficult than reconstructing car crashes. The obvious differences between a bicycle and a car are what make bicycle accident reconstruction more difficult. With only two wheels, a bicycle requires balance to maintain control. In addition, a bicycle has a higher center of gravity and a shorter wheelbase than a vehicle. Crash Tech bicycle crash experts are trained and certified in bicycle crash investigation and reconstruction through the University of North Florida.
Here are a few ways a bicycle can fall without a collision occurring.
- Low side – When a bicyclist leans into a curve and the front wheel loses traction. This can occur from braking, due to a slippery spot or because of an issue relating to the rear wheel.
- High side – Similar to a rear wheel low side, but more dangerous. A loss of traction and then traction is regained, but control is lost. Can result in a pitchover.
- Pitchover – When too much front brake is applied, the rider typically tumbles over the bars. Bicyclist deceleration is limited. Other causes include, something hitting the spokes or the bike hits a fixed object. Pitching causes are typically determined by the amount of acceleration and how high the rider is.
When questioning a bicyclist about an accident, it’s important to ask if he or she was trying to regain control or avoid an impact. Also, an investigator needs to ask about cyclist experience (Find out how skilled that cyclist is).
Proper training in bicycle crash reconstruction is necessary as the evidence from the crash scene is very different from an automobile crash. Consider these differences below and you will see why finding properly trained investigators is necessary.
Car v. Car evidence may include:
• Gouge in roadway
• Crush damage
• Rest position of vehicles
• Tire marks on roadway
• Event data recorder
Car v. Bicycle evidence may include:
• Rest positions; however, this is rare.
• Tire marks
• Injuries
• Bike crush
