Trail Evo


The Trail Edition brought along a revolution in mountain bike lighting in 2017 with an enormously wide and evenly lit beam pattern while maximizing every lumen. Trail Evo builds on that incredible light and improves the beam pattern, even wider and stronger than before, while removing the external battery and incorporating a unique quick release mechanism that is cleanly integrated into your cockpit.

  • Centered out-front quick release mount, made of die cast aluminum.
  • 150+ minutes of strong output, with the ability to charge-on-the-go.
  • Customized USB-C cable creates a waterproof seal while in use.
  • Incredibly wide beam pattern designed for trail riding.
  • Smooth falloff all around the bike enhances peripheral vision.

In stock! Order before 2pm CST and should ship same day.

When we developed the Trail Edition back in 2017 we set out to use the same principles from car headlights and bring them to bikes. Focusing not on big lumen levels but rather a high quality beam pattern that is optimized for twisty singletrack.

Over 4,000 customers and counting absolutely loved it. But we knew we could do better. After a year and a half of development we are excited to show you the latest evolution of our best selling light. Trail Evo


What did we improve?

To begin, we built on the development of the Trail Edition and Hangover, along with perfecting our unique blended-TIR approach to trail lighting. We spent hundreds of hours in simulation and prototypes to hone in on an even better beam pattern. Wider than the Trail Edition everyone loves, with more peripheral lighting along with a stronger center intensity to see even further down the Trail thanks to a boost in total lumen output. The difference is staggering.

The blended TIR optic uses precision engineering to finely tune the beam shape, eliminating the typical “round hotspot” edges by redirecting portions of the beam to where you need it most, creating a dramatically smoother beam. The surrounding “Light Carpet” around your periphery allows you to see and react to the whole trail and not get “tunnel vision” with harsh edges.  The smoother the beam, the less strain on your eyes, the better you can see and the more comfortable your night ride is.



Just as important as beam patterns, is thermal management.  When we start pushing big power output like this, we have to worry about shedding that heat to keep the LED’s in their efficient operating range. We utilized an incredibly unique way of flowing air THROUGH the light, allowing for cooling air to pass directly behind the LED’s. An industry first.

We then turned our sights to eliminating one of the main complaints most riders have these days: you don’t want to carry around an external battery pack. We get it, it’s cumbersome, takes more time to strap to your bike frame, and leaves cables flopping around. Thankfully there have been lots of developments in battery technology in the last few years and high density 21700 cells have gotten better and better. So we integrated two of them into the housing of Trail Evo, resulting in a whopping 37.0 watt-hours with only 275g of weight.

This combined with using new high-efficiency genuine CREE XD16 LED’s means we can get an incredible amount of light while maintaining 2.5+ hours of usable runtime, without an external battery pack!

Combine that featherweight with the fact that we can run this light at 150+ minutes of usable runtime and you start to wonder what else you could possibly need. Need to last longer than that? We are one of the only bike lights on the market that offer pass-through charging, so you can hook up any USB power bank you may own and it will supplement the light as your ride goes on, giving you unparalleled flexibility for your specific riding needs.


Let’s talk about runtimes for a second. The bike light industry tends to like to use the FL1 standard, which rates runtime as the time it takes to go from full brightness to 10% output, an outdated measure that harkens back to the days of using Alkaline batteries, and when you would swap out your flashlight battery…..

But this is 2020. We need to get real about runtimes. Nearly every single light on the market starts out full brightness and diminishes over time, and this is okay. Our eyes adapt to the darkness and as long as the reduction is gradual, we literally cannot tell the difference until reaching about 50-60% of the perceived brightness.  Which is why we say that we have 150+ minutes of usable runtime in our standard Adaptive Mode, we aren’t going to call this “high” anymore and have a mode that isn’t actually high…. we made that mistake once.

Here is the expected runtime chart. This should be far more useful then just a single number.

Our High, Medium and Low Modes are SOLID output modes that are designed for the rider that changes the light intensity often. Low and slow for the climbs, maximum output for the fast descent. Medium is the perfect setting when paired with the Hangover on the helmet to get nearly 4+ hours of runtime.  Adaptive is for the rider that hits the trail hard right from the parking lot and doesn’t want to think about changing output often. Just set it and forget it and get 150+ minutes of runtime.

Every mode has a 20-minute reserve that drops to low, we don’t want you getting stuck in the woods with no warning, or no way to get out in time. Plus let’s be honest, if you left it on high you probably were really only going to get another 3 minutes of runtime before totally going out, so lets put in a safety measure…

Outfront Centered Mounting

For a bar light to act like a proper headlight, we need to put it in the best location for a headlight. Out front and centered on the cockpit. For this we developed a durable and easy to use quick release mounting system that has been used for years in the professional camera industry. You simply click the light in and tighten the over-cam, and with one hand can release the light. We designed this to be used easily with thick gloves.



Standard USB-C Quick Charging

Just like with Hangover, we have USB-C quick charging as standard. This allows you to quickly charge the light using anything you might already have. A USB QC 3.0 compatible external battery pack will work to charge Trail Evo while in use, or before you hit the trail. In Medium output you can extend runtime by several hours.


With Trail Evo, while not as quick to charge as Hangover (single 18650 battery vs. two 21700 cells) it still charges at higher power than any other self-contained light on the market without requiring a proprietary charger, because we don’t want you to ever have to deal with mis-placing a charger that you can only get from one place. Trail Evo can each >80% charge in <3 hours.


The included customized USB-C to USB-A cable is designed to create a snug and watertight seal around the USB port of the light.

Amazing Light!

Just used the EVO during a 24 Hour Race and loved it! My night laps were just as fast as my day laps cause the light worked so well! 100% would recommend to anyone!

Best first light i ever bought!!!

My first bicycle light does not disappoint!!! I love my fx1 disc bicycle more because of the night time ridong!! I also love the light and the customer service are very responsive!!! Looking into adding more lights in the future!! Thank you for everything!!!

Best Light I've Ever Owned

The Trail Evo is amazing the beam spread can be perfectly directed to highlight, not only directly infront of you, but your peripheral view as well. Since some of the other guys I ride with have Outbound lights the thing I noticed right away was that when they're behind me on the trail the lower beam pattern doesn't affect the rider in front on the fast descents as much as some of the other products available. I did have and issue with my mounting bracket which cracked when I flipped the bike over to fix a chain issue but I emailed Outbound and they admitted there was an issue with the earlier versions of the clamp. They sent me 2 of both bar sizes and stickers. They get 5 stars because the product is superior and they look after their customers. If you mountain bike at night a Trail Evo will enhance the experience.

Great light and OUTSTANDING customer service

I joke that I could knock a plane out of the sky with my EVO as bright as it is and am very, very pleased with the light. I have been night riding since night riding first became a thing for mtn bikes (mid 90's) and this is far and away the best light I have had. I have had friends pay exorbitant amounts for brighter, but this is more than enough for me - and I ride fast at night. From a cost/benefit analysis - with durability, I think you will be very happy (and I have owned everything from cheap Chinese lights to top end American brands).

Let me also say that the customer service has been OUTSTANDING. I reached out twice, both on weekends, and got immediate responses. Each time they not only solved the issues (1 - my helmet didn't align with their mount so they sent me free one that would/2 - I crashed hard into a tree, hit the mount square (during daylight so EVO was not on) and lost the mount so they sent me a free replacement with a promise of the next gen one (also free) when it comes out in a few weeks).

Very, very pleased and will be sporting both my Evo and Hangover at 24 Hours in the Canyon (Palo Duro - Tx) in two weeks!

Lighting up the whole night

Amazing and easy setup. I can now see what those dang raccoons are up to in my tree when I get home from my ride.

Best MTB light I have seen!

I decided to bite the bullet and pull the trigger on the trail evo light after using my cheap dual led set up I got from Amazon several years ago. The all in one package makes it easy to go for a night ride. Just clip on the light and go. No using Velcro straps for the batteries and wires and some rubber band straps that barely hold the lights in place around your handle bars. Since beam pattern was so small it was critical they were aimed correctly. The outbound trail evo blows them out of the water in every way. The coverage area is huge! Battery will last longer and can be charged while using for infinite life if you need it. 24hr race anyone? It’s high quality and nothing more that I can ask for. I am able to ride at the same speeds at night as I do during the day. It works that well. I’m glad I pulled the trigger to get out of the dark. Pic comparison below: bright spot was old system. You can’t even see the old lights when both are on together. And these pics don’t do it justice. There is just a huge flood of light all around the front of you making it really easy to see everything at speed. Even DH runs at 20+ mph!

It's beyond "good"

I've tried a few different lights. Waste of money. I should have stuck to my "by once cry one" attitude. Is it a little bit more expensive? yes. Should you care? No. The difference is astounding! Don't think about it. Just do it. Worth it!
