I have just been back from a biking vacation with another fellow cyclist, and we have met a lot of other cyclists: from the most serious ones to those taking the bike once every eon.
When we had to overtake a group of cyclists, our procedure was:
- check if there was oncoming traffic in the front
- check if there were cyclists on the back
- ring the bell to alert about a bike overtaking
The problem we faced pretty often was that, if there were some cyclists pedaling next to each other talking, they would move in line and then, after being overtaken by the first cyclist, would get back side to side while the other one was still overtaking, sometime even zigzagging while doing so.
This is a risk per se, but when we were on a cycle path in the woods it was even more dangerous, as there was not that much space for a different trajectory and we had panniers on both sides.
Therefore my question: how can I clearly communicate how many bikes are overtaking a group of cyclists?
