Bicycle-on-bicycle collisions may not grab headlines like car crashes do, but they’re surprisingly common—especially in cities, on shared trails and during group rides. These accidents can result in serious injuries, from broken bones to concussions, and are often more jarring than expected due to the speed and close proximity of cyclists.
Bicycle-on-bicycle crashes typically stem from subtle misjudgments or overlooked etiquette between riders. Understanding the main causes can help prevent these incidents and foster a safer, more respectful cycling culture.
1. Lack of communication during group rides
Riders are expected to call out obstacles, signal turns and communicate intentions like slowing down or stopping. When communication fails—whether due to inexperience, distraction or overconfidence—those behind have no time to react. Even experienced cyclists can misjudge another’s pace or forget to announce a maneuver, leading to avoidable accidents.
2. Inconsistent riding behavior
This issue is especially problematic in mixed-experience groups, where newer riders may not yet have the control or awareness needed to ride predictably. Even slight wobbles at low speeds can cause handlebar tangles or crashes. Riders passing too closely without warning can also startle others and lead to loss of balance or reactionary swerves.
3. Poor situational awareness
A third major cause of bike-on-bike collisions is simply not paying attention. Cyclists may become engrossed in conversation, overly focused on their cycling computer or lulled into a false sense of security on familiar routes.
This lapse in situational awareness can lead to rear-ending another cyclist, drifting into someone’s path or failing to notice changes in group dynamics or road conditions. Cyclists who ride with earbuds, ignore visual cues or fail to maintain proper following distances are particularly vulnerable to collisions.
While bicycle-on-bicycle collisions may seem minor compared to car crashes, they carry real risks, especially when speeds are high or riders are closely packed. Cyclists who get involved in these collisions should enlist hands-on legal guidance to identify the at-fault parties.
