How bright should my front bike light be?
For relaxed city rides, 30 to 50 lux is usually enough. Riding on unlit bike paths outside the city is more comfortable with 60 to 100 lux. On dark country roads or at higher speeds, you should aim for at least 100 lux – this is where powerful rechargeable bike headlights and premium e-bike systems deliver the beam strength you need. Rule of thumb: slightly more light is always better than too little.
