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.

Back in stock and ready to rock!

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.

Soooo good!

Only had a few rides using this and the hangover combo, but it’s so awesome, it feels like I’m cheating with the amount of usable light that this thing puts out! Great work and I’m recommending it to all of my buddies that do night rides too!

Bright light, great customer service!

This trail Evo light is incredible! I also had a very minor technical issue with the light when I received it and the crew at outbound lighting was very responsive and handled it immediately, I highly recommend this company and this product

Shipping problems

I never received the light. UPS said they left it on my steps. UPS denied my claim and had to reopen it.

Amazing light

I just can't say enough nice things about this powerhouse.


The original OL Trail light was second to nothing on the market. The only thing I would have loved was a center mount on the handlebars out of the box and internal battery. They did with the new incredible EVO TRAIL light! The craftsmanship and light output is next-level! Cheers to the Matt and the OL Team for another epic product and the best customer service in the industry!

So far so good

Had an issue with the bracket when setting it up.
Contacted Outbound and received 2 replacements in hurry. So customer service was great. And they said they are working on a revision to help avoid the issue I had, so they are actively improving their products. Have only had a chance to use this once so far. It is really friggin bright on high, especially compared to the light I had been using for years. Next time I'm going to try the adaptive mode. The light pattern is well designed. Mounts up easily and send secure. One complaint is that the usb jack is inside a deep well, so that it could be covered to make it waterproof. But because of that, the usb cables I had laying around couldn't be used to charge the light... They wouldn't fit into the well. I had to use the cable that came with the light.

Great Light, and much better than my old school NR lights

I have the EVO and Hangover, and they are great lights! The EVO honestly is bright enough, with a broad enough beam, that you could almost get by with it alone. The only time I find it is really necessary to turn the hangover on is on switchbacks where the EVO is pointed too far the wrong way. Battery life is great for by rides, and I love the self contained packaging. My last lights were an old school set of NR lights (HID head and dual halogen bar) with big, heavy remote ni-cad packs and wires that were a tangley pain. Great product.

They are who we thought they were.

The hype is real. I brought these in to sell in my shop after doing exhaustive research on self-contained lights. I kept a set for myself, the rest sold out in 24 hours, and the users are raving about them.These lights get my absolute highest recommendation.

Super bright! Great spread

Great light, bright and wide view. When I road with my friends, my light, the Trail Evo, was by far the best light out of the group. Would recommend to any mountain biker.

So much light

The light is chonky, but the mount is great. My first ride was in the snow, and I ran it on Low the whole time. Still the most light I've ever had on the bar. Just wild.
