I think it's worth its price. It dazzles like the sun. It weighs almost nothing. Waterproof. Easy to mount in two different ways. I think if someone is looking for a specific light that won’t let you down during a ride, this is it.

Very good rear light, above all it is very powerful. At night you can see the cyclist from afar because it shines so red. The battery lasts a long time, I have nothing left but to recommend it.

A nice option for cyclists. The light is easy to charge, has many modes and a smart option, so you can increase your visibility during the day and not drain the battery.

Simple, durable, and good-quality bike light. It has several lighting modes, so it works in many scenarios. A big plus for USB-C charging and the included cable.

I bought one piece to check the product quality. I needed three lights. Now the lights are mounted on every bike.

Olight once again proves its class, a small but very visible light with a brake sensor option, perfectly hidden USB-C port, two types of mounts included—saddle rail or classic silicone strap with a solid latch so you don’t lose it.

Very good bike light, this purchase convinced me to buy another product from this manufacturer. The lamp works great. It has many lighting modes, thanks to which you can choose the right one for your ride or the weather conditions. IT SHINES VERY WELL, it is visible in all conditions. Highly recommended!

The light is very well made, the housing is solid. The light is clearly visible even on a sunny day and from several hundred meters away. Mounting on surfaces other than tubes is a bit problematic, but manageable. I ended up mounting it on a child seat and it works perfectly.

Everything matches the description. The store shipped the goods quickly and secured them well. Very bright flashlight. Made of high quality. Many options and convenient mounting under the bike saddle.

The Olight BS 100 rear bike light is a solid choice for any cyclist who values safety and visibility on the road. Its brightness and intensity make you easily visible even in difficult weather conditions and at night. The light offers several lighting modes, allowing you to adjust its function to current needs and road conditions. The compact and lightweight design makes the Olight BS 100 easy to mount on most bikes, and the durable construction ensures long-term reliability. Additionally, the built-in high-capacity battery provides long hours of operation on a single charge, which is very convenient for regular users. However, it’s worth noting that the mounting mechanism may be a bit less stable on very uneven roads, which might require more frequent checking and adjusting of the light’s position. Despite this, the Olight BS 100 is an excellent rear bike light that provides safety and peace of mind when riding. It is a product that will certainly meet the expectations of most cyclists.

Great light. Excellent visibility and a sufficient variety of modes. The brake sensor already proved useful and stopped someone from hitting me from behind. A small minus for the saddle mount, which is too narrow for Selle Italia; I had to attach it with a zip tie and now it shines upward, like in the photos. I'll have to come up with something, they could have put more effort into this detail.

Olight, as usual, rose to the occasion. They made a small, handy rear bike light. It is very bright and thus promises that the cyclist will be visible and safe on the road.

Great light. Lots of different modes, although most are very bright. I personally use the weakest flashing mode with the brake function, which literally blinds. The mount holds very securely, and the battery lasts amazingly long. I am very satisfied.

A small but powerful "smart" rear light with several interesting modes, easy to mount, charges quickly, and the battery lasts a long time. The lamp is resistant to flooding during heavy rain.
