Nighttime cycling involves riding a bicycle after sunset, often in low-light conditions. Cyclists should prioritize safety by wearing reflective gear and using lights on their bikes. This helps increase visibility for both the rider and other road users. Riding at night can offer a unique experience, as the cooler temperatures and quieter streets create a different atmosphere compared to daytime cycling. However, it is essential to be aware of potential hazards, such as uneven surfaces or reduced visibility, and to choose well-lit routes whenever possible.
