Is the Air Quality Safe
for Cycling Today?
Real-time air quality check for cyclists. Based on WHO and EPA guidelines for outdoor cycling.
Why Air Quality Matters More for Cyclists
When you cycle, you breathe 5–10 times more air than at rest. Cyclists in urban traffic also face elevated exposure to nitrogen dioxide (NO2) and ultrafine particles from vehicle exhaust, not just the general ambient AQI. Choosing routes away from busy roads can cut your exposure substantially. Studies find reductions of 30–70%.
AQI Thresholds for Cycling
Use this table to decide whether to ride outdoors based on current air quality. These recommendations are based on EPA and WHO guidelines adapted for cycling.
| AQI | Level | Cycling Recommendation |
|---|---|---|
| 0-50 | Good | Ideal conditions for cycling. Enjoy your ride! All intensities safe |
| 51-100 | Moderate | Most cyclists can ride normally. Consider reducing intensity if sensitive |
| 101-150 | Unhealthy for Sensitive Groups | Sensitive riders should limit outdoor cycling. Reduce intensity or duration |
| 151-200 | Unhealthy | All cyclists should limit outdoor riding. Consider indoor training |
| 201-300 | Very Unhealthy | Avoid outdoor cycling. Move workout indoors |
| 301+ | Hazardous | Do not cycle outdoors under any circumstances. Indoor activity only |
Road Traffic Pollution: The Cyclist's Risk
Vehicle Exhaust Exposure
Cyclists riding alongside traffic inhale elevated concentrations of nitrogen dioxide (NO2), carbon monoxide (CO), and ultrafine particles from vehicle exhaust. These are not always reflected in area-wide AQI readings, which measure ambient levels at monitoring stations.
Route Choice Matters Most
Research shows that cycling on back streets and park paths versus busy main roads can reduce pollution exposure by 30–70%. Aeriqo's route analysis lets you compare air quality segment by segment so you can plan the cleanest possible ride.

Frequently Asked Questions
What is a safe AQI for cycling?
An AQI of 0–50 is ideal for cycling at any intensity. At 51–100, most cyclists can ride normally, though sensitive individuals may want to reduce effort. Above 100, all cyclists should consider shortening or modifying their route.
Are cyclists more exposed to air pollution than pedestrians?
Yes, cyclists breathe harder and are often closer to vehicle exhaust on roads. Studies show cyclists inhale 2–3 times more air pollution per hour than pedestrians, even when ambient AQI readings are similar. Route choice away from heavy traffic makes a significant difference.
Should I wear a pollution mask while cycling?
N95 or KN95 respirators can filter PM2.5 but make breathing during intense cycling difficult. The most effective strategy is to choose routes with lower AQI and avoid peak traffic times. For commuters, even small detours onto quieter streets can meaningfully reduce exposure.
How can I find cleaner cycling routes?
Aeriqo's route planner lets you draw or upload a GPX/TCX route and see air quality for each segment. You can compare different route options and find the time window with the best air quality for your planned ride.
