Olight BS 100 Rear Bicycle Light - 100 lumens

I think it is worth its price. It shines very brightly, is lightweight, and waterproof. You can mount it in two ways. If someone is looking for strong lighting that won't let them down while riding, this is the perfect choice.

Very good rear bike light, most importantly very strong – the cyclist can be seen from a great distance. The battery lasts a long time, so I can confidently recommend this product.

An interesting option for cyclists. It is easy to charge, has many operating modes, and a smart function that increases visibility during the day and prevents rapid battery drain.

Simple, durable, and solidly made bicycle light with several operating modes, making it suitable for various situations. A big advantage is USB-C charging and the included cable.

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

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

The Olight BS 100 rear bicycle light is a great, compact, and convenient USB-C rechargeable light. It is sturdy, very bright, and extremely efficient. I can recommend it with full confidence.

This is a very good bike light that convinced me to buy more products from this brand. The light works great, has many lighting modes that you can adjust to your riding style and the weather. It shines very well and is visible in any conditions. Highly recommend!

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

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

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

The light is great, provides excellent visibility, and has many modes to choose from. The brake sensor has already proved useful – no one has rear-ended me. A small downside is the seatpost mount being too narrow, so I had to use a zip tie, and the light points slightly upwards. This part could use better design.

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.

Great lamp with many lighting modes, although most of them are very intense. Personally, I prefer the weakest blinking mode with the stoplight function, which is very bright. The mounting is stable, and the battery lasts a very long time. I am completely satisfied.

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