Should be 20€ max, or 30€ with auto on off. it was over 50€...

- Manuel 7 February 2026

I thought it was auto on-off, i though leds would be all put in a circular way with no weird spaces in between

Pros & Cons

usb-c charge
Very bright
AliExpress old model costs 18€ & it's better
Big and bulky
Easy to steal with a wrench
Expensive, no auto on off
ugly green side light

I've always used the German manufacturer for lights for outdoor activities, but unfortunately the only thing I can't manage is the rear light in terms of visibility during the day. Especially on mountain passes or winding roads........ Now I have found a super lamp that will hopefully last a long time.

Best rear light

- Anja 3 January 2026

Excellent illumination. I have been riding my MTB 3 times a week all year round for over 10 years. It couldn't be simpler or better. Suitable light modes for all weather conditions. The brake light cannot be overlooked when slowing down. Absolutely superb.
