Olight BS 100 Rear Bicycle Light - 100 lumens

I believe it is worth its price. It shines very brightly, is lightweight and waterproof. It can be mounted in two ways. If someone is looking for a reliable light that won’t let you down while riding, this is the ideal choice.

Very good rear bike light, above all very powerful – the cyclist is visible from a long distance. The battery lasts a long time, so I can confidently recommend this product.

An interesting option for cyclists. It's easy to charge, offers many operating modes, and has a smart function that increases daytime visibility and prevents quick battery drain.

A simple, durable, and well-made bike light with several operating modes, making it suitable for different situations. A big advantage is the USB-C charging and the included cable.

I bought one to check the product quality. I needed three lights and now each one is mounted on a separate bike.

Olight proves its class once again. A small but highly visible light with a brake sensor, hidden USB-C port, and two mounting options: under the saddle or using a silicone strap with a sturdy clasp.

The Olight BS 100 rear bike light is an excellent, compact, and convenient light charged by USB-C. It's robust, very bright, and extremely efficient. I can recommend it with full confidence.

This is a very good bike light that convinced me to purchase other products from this brand. The light works excellently, has many lighting modes that can be adapted to riding style and weather. It shines very well and is visible in all conditions. Highly recommended!

Very well-made lighting with a solid housing. The light is visible even on a sunny day and from a long distance. Mounting on other surfaces than tubes can be a bit tricky, but it's manageable. For me, it works well on a child seat.

The product description matches reality. The shop sent the package very quickly and secured it well. The light provides very bright illumination, is solidly built and is easy to mount under the saddle. It also offers many lighting modes.

The Olight BS 100 rear bike light is a solid option for anyone who values safety and good visibility. The intense light makes you visible even in tough conditions. Various operating modes allow you to adjust to your needs. The small size and light weight make installation easy, and the durable construction ensures reliability. The built-in high-capacity battery guarantees a long operating time on a single charge. The only downside is less stable mounting on very bumpy routes, so you sometimes need to readjust the light. Still, it's a great light that will meet the expectations of most users.

The light is superb, provides excellent visibility and has many modes to choose from. The brake sensor has already come in handy – nobody has run into me from behind. A small minus for the saddle mount being too narrow, so I had to use a cable tie and the light shines a bit upwards. This part could be better designed.

Olight, as usual, did not disappoint. They created a compact and convenient rear bike light that shines very brightly, ensuring the cyclist's visibility and safety on the road.

A great light with many lighting modes, although most are very intense. I personally prefer the weakest flashing mode with stop light function, which is very bright. The mount is stable and the battery lasts a very long time. I am fully satisfied.

A compact yet very powerful smart rear light with several interesting modes. Easy to mount, charges quickly, and the battery lasts a long time. The light is resistant to heavy rain.
