Have the Philips Safe Ride on my MTB with a hub dynamo. The functions are eiwandfrei. There headlamp with sensor attached to a B & M, it will switch itself alone an at dusk. The LEDs provide a bright light, which is good to see and the light band is a beautiful design, which is not to be found anywhere. Installation was easy, but no cable was in what has puzzled me somewhat. Had luckily himself yet what. The holders of the cable can be realized either via plug-in shoes or a clamping mechanism. Well, we must not go into a special cable, but can use any normal.
Conclusion: Good lighting, great design, has my buy recommendation.
