Review on 🚴 Ultra Bright Smart Bike Tail Light: USB Rechargeable, Auto On/Off, Waterproof LED – Perfect for All Road Bikes! by Stephen Good

Although the product name is not mentioned by this seller, it is X100 smart light that is packaged with this brand. It's compact and rugged, with a small auto/manual switch on the back. It screws onto the bike mount and you unscrew it to charge it. I read the reviews before buying, so I only use it in manual mode. So I don't rely on it for motion detection. If I stop for a while I just turn it off like any of my old lights. What attracted me was the brake sensor in case I'm traveling with someone. As I use it I find it works as advertised. My only complaint is why I am giving this product 3 stars instead of 4 or 5. It comes with a seat mount and 4 cable ties. This bracket will prevent you from installing the bag in the back seat and you will need to move the seat backwards to make room for the zip ties. I slide my seat all the way forward. There is a solution and it is shown in the instructions that came with the flashlight. The seatpost mount can be purchased separately for $8.99.

The seat mount is unsuitable for most cyclists, as noted by other reviewers. I ordered a bar mount and I'm ready to go!
