Charge Time

If you’re still on the road and the sun is already setting, It's important to be aware of the risks posed by riding in low visibility conditions.

Looking for a powerful yet lightweight bike light for your gear? The Bontrager bike light has a dimension of 28.9 L x 28.2 W x 37.3 H (mm) and weighs 40g—making it easy to mount and remove from your bike frame.

Waterproof Rating

This best rear bike light also features a waterproof rating of IPX7, which means it can be submerged in water up to 1 meter deep for up to 30 minutes. So, whether you're caught in a rainstorm or your light takes a spill in a puddle, you can rest assured that it will keep shining. Overall, the Flare RT will help you if you’re looking for visibility or peace of mind while commuting during the day or riding at night.

Here are other notable details of the Bontrager rear light.

Ultimate Daytime Visibility

Day or night, rain or shine, the brightest rear bike light ensures that you'll be visible to everyone on the road. 

It features a solid build and emits a powerful beam up to 90 lumens with different brightness levels: high, low, and strobe, allowing you to customize your lighting depending on how bright it needs to be.

Light Sensors for Auto-Adjust Brightness

Have you ever been riding at night and felt like you needed a strong light but weren't sure how much to turn your light up? The Bontrager Flare RT rear bike light has an auto-adjust brightness function that will automatically adjust the brightness of the light depending on the surroundings. This setup means you'll always have the ideal intensity of radiation.


Cyclists are prone to accidents because of weather conditions. Bontrager's Flare RT rear bike light is designed to keep you safe while riding in dry or wet conditions to avoid this kind of circumstance as this light is easily rechargeable and features a robust design that can stand up to the toughest environments.

Switching Modes

Bontrager's Flare RT rear bike light has a killer flash mode that can run up to 12 hours and a steady mode up to 13 hours for those moments when you need extra visibility. 

This light has your back (literally) no matter what kind of ride you're on. So whether you're headed out for a leisurely spin around the block or an epic cross-country adventure, make sure to strap on the Bontrager Flare RT rear bike light.

Quick Connect Brackets

Install your Bontrager Flare RT rear bike light quickly and easily with the rear quick connect brackets. This new design is also much more secure, so you can rest assured that your light will stay in place even on the roughest of rides. 

No more fiddling with screws and bolts; pop the light into the bracket, and you're good to go. 

Bluetooth Smart

Bike riding at night probably doesn't feel good for some reason. But with the right gear, it can actually be quite enjoyable and safe! 

The Bontrager Flare RT rear bike light is a great option for anyone looking for a high-quality, reliable rear bike light. And with its Bluetooth smart technology, it's easy to keep track of your battery life and turn on and off without having to take your hands off the handlebars. 

Few Quirks

Bontrager's new Flare RT rear bike light is one of the brightest and most visible on the market, but it falls short in a few key areas. 

Incompatible for Mounting Bracket 

The Bontrager Flare RT is a great rear light, but there's one catch: the mounting bracket isn't compatible with some bike racks. The light may fit properly into the bracket, but the screw used to secure it in place rubs against and damages the light.

So before you purchase, inspect your bike seat post if it's compatible with the light item.

Light Design Issues

While the light is bright and does a good job of lighting up the road, Flare RT rear light's placement on the bike can cause problems.

For example, you ride your bike on any road you're on whenever you get the chance. Unfortunately, the light is located too close to the center of the bike, which can make it difficult to see when riding in accident-prone areas like mountains. 

Faulty Rear Light

Biking can be dangerous—even with the best bike lights. You're zipping along, enjoying the cool breeze on your face and the workout when suddenly your bike light starts flickering off and on for no reason.

It isn't very pleasant. So when it happens, swap out the old batteries for new ones, and your light should be good as new.

Safe Rides With The Best Rear Light
