Stop buying batteries for your bike lights.!!

I have been a Reelight customer for about ten years. I cannot understand why (a) these are not marketed heavily in bike stores across the country. And (b) why anyone who rides a bike does not have at least one pair of the different models that Reelight makes. Not only do they not use batteries, but they are designed to install easily, are designed with the bike rider safety in mind - having blinking light visibility even when stopped, and are super durable in rain and cold weather. The engineering , design and practicality are top drawer. Break free from batteries once and for all.

Thank you so much for your kind words, Craig! Of course we couldn't agree more :)

Die vordere Halterung passt leider nicht

…an meine Federgabel. Gibt es einen Adapter oder andere Halterung?

Hi Axel,

If you have a standard quick release you will need our adapter ( Please write to us directly at so that we can give you better support. Thank you.

Halterung etwas aufweiten

Ich musste die Halterungen für vorne und hinten mit dem Dremel etwas aufweiten, damit sie auf die Steckachsen passten. Um die Leuchte vorne nahe genug an die Magneten zu bekommen, war es nötig, die Halterung zu biegen. Ansonsten wären mehrere Zentimeter Platz zu den Speichen gewesen. Danach funktioniert das Licht wie erwartet. Ich setze die Reelights bereits seit vielen Jahren an meinen anderen Rädern ein.

Thanks a lot Andreas for sharing your experience. Sometimes the lights does not fit out of the box but I am happy to hear that you worked out a solution on your own.


Très rapide à installer, pas besoin de la notice. Et très efficace.

Merci beaucoup Cyrille !

Heavy but worth the comfort

I wanted lights, that do not need to be turned on and off. I did not want to care about that each time I ride. The bike is a mean of transport for me, so the less buttons to push and things to remove and install, the better. This comfort comes with a price though, they weight 300gr and you can feel the magnet "friction", especially if you have a heavy bike and ride uphill. Its not dramatic at all, but it is there.
My rear light got stolen for some reason. I appreciate the possibility to buy only spare parts and not the whole set. Unfortunatelly, the delivery to CZ costs almost as much as the spare parts themselves and I can't even proft from the free delivery, because its valid for sellected countries only. Thats how it is, just it does not make you happy.
In overall the Reelights SL200 is a great product, I am glad for having it. What could be really nice to have is a product that has a GPS tracker inside.
