Evo Downhill Package!

Behold the Trail Evo. The sum total of our decades of experience designing automotive optics, all neatly wrapped up in the best bike light we have ever engineered.

Featuring a panoramic, perfectly even beam pattern that we fine-tuned the heck out of to meet the demands of trail riding. With a smooth falloff all around you to aid peripheral vision (the beam should fall off, not the biker). With it we created a literal wall of light that illuminates your entire field of view.

A quick-release fiberglass-reinforced nylon mount that we, ahem, “borrowed” from those clever camera guys to keep this bike light pointing in the right direction.

Good for 150+ minutes of strong output and, should you need it, the ability to USB-C quick charge on-the-go.

Proudly and capably made just down the trail in Chicago IL.

Daylight at night

The Trail EVO light is such a tremendous upgrade. The light is wide, bright and provides so much light that it’s like riding during the day. Also the pass through on the fly charging is a game changer. I use a small handle bar bag and run a small cord from my power charger to the light itself and can run for almost 10 hours at night. Also the customer service level is second to none and Tom makes sure that his customers are always out first.

This is the one!

It's so refreshing to put my hands on a product that does everything right. As claimed in the product description, Outbound's engineers checked ALL the design boxes (the big and the small details) and made no compromises. I love how easy it is to use and the FULL use of the USB-3 standard. High-quality materials and manufacturing. I would expect to pay more than the $300.

Well engineered for mountain biking.

The most impressive mob light I’ve owned this far. The only one i know of that was designed for trail riding with really wide beam pattern and sufficient brightness that gives the rider excellent peripheral vision. Most other lights have narrow patterns and make it difficult to see obstacles on the trail.

The Bike Light evolution:
How & why we designed this light

When we launched the Trail Edition back in 2017 it was a game changer for bike lights. A beam pattern specifically designed for trail riding with a wide evenly illuminated distribution. However it required an external battery pack, and we had lots of customers wanting to go wireless.

So we took the best parts of Trail, and evolved it into the Trail Evo. Bringing a long lasting, even brighter, even wider beam pattern to your handlebars, without any external cords.

Read on for more nerdy design details!

Advanced Optical Engineering

When we developed Evo’s beam pattern, we knew we could go wider and brighter, so we redefined our illumination goals, target candela points, beam angles, and then went to work simulating, testing, prototyping and developing the most seamless pattern we've built to date.

The extreme width is thanks to the finely tuned blended Total Internal Reflection (TIR) optics. Hundreds of simulations with Lucidshape software let us squish, squeeze, stretch and shape the light to hit that perfect balance of peak brightness, smooth falloff and insane peripheral coverage.

Check the slider comparison below to see the difference between a fine tuned optical instrument such as Trail Evo vs a name-brand light that has been around for years. The difference is staggering in person.

Advanced Optical Engineering

Mind blowing, incredible, and game changing are a few of the words used to describe how seamless and bright the Trail Evo beam pattern is.

Always hard to capture in photos or videos, best experienced in person. You won't regret it.

Looking up at Trail Evo Bike Light showing USB-C charging

USB-C Pass-thru Charging

Everyone has USB charging ports all over nowadays, so we make sure you can use any of them with the Trail Evo, including almost all QC 3.0-rated chargers for super fast recharge times.

But we took that concept one step further and added Pass-Thru Charging (PTC) to allow you full access to all output modes of your light while charging from an off-the-shelf USB Power Bank, so that you can extend runtime for those epic adventures, without limiting the light available to you (bikepackers rejoice!).

We even customized the included USB-C cable to seal against the elements when plugged in so you don’t need to worry, just ride.

USB-C Pass-thru Charging

We were one of the first to offer USB-C charging as standard, except we took it a step further by offering pass-through charging as well.

This lets you plug in any USB power bank and charge the light while in use, in any mode. Game changer for 24 hour races and extra long night rides!

Rock Solid Mounting

A good light isn’t so good if
it’s bouncing up and down on the bars all the time. That’s why we made a bolt-on clamp mount for Evo so it’s solidly locked to the bar, With a simple shim it adapts from 35mm to 31.8mm bars and the beam won’t shake around like lights with rubber strap mounts do.

We adapted an established
camera tripod mount concept then miniaturized it for slick snap-in installation with a ramped-cam that always takes up the slack as it wears, so you never have a rattly interface, and an easy one-handed quick-release process to pop the Evo off post-ride to charge.

Simple User Interface

Few people read instruction manuals, even fewer want to, so we keep our lights dead simple so that you don’t need an advanced degree to remember some complicated sequence of button presses get to the mode you want.

Evo’s soft-touch overmolded top shell has a single, large button right in the middle that’s easy to feel through a thick winter glove in the dark, with four green indicators to clearly convey mode and battery status without the need for a decoder.

Four simple modes cover the majority of use cases from set-it-and-forget-it pedally XC to long-climb-fast-descent Enduro rides – Adaptive / High / Medium / Low – and no SOS or seizure inducing strobes stuck in between.

Skillfully built by our passionate team (and robots) while listening to a lot of podcasts.
PCB design of Trail Evo Bike Light

Electrifying design

We like to keep our lights simple on the outside for the user, but that doesn’t mean we’re skimping on the guts inside. The constant-current driver maintains rock solid regulation through the Cree XD16 LEDs over the entire voltage range of the genuine Samsung 21700 cells with a unique battery monitoring algorithm to give you accurate feedback without interruption.

Complete with fast QC 3.0 USB-C charging and Pass-Thru capability to boot, we engineer the electronics to maximize efficiency and runtime while minimizing charge times, all without any proprietary connectors that could leave you stranded.

Our lights look simple on the outside, but that doesn’t mean we’re skimping on the guts inside.

Nine genuine Cree XD16 LEDs powered by two genuine Samsung 21700 cells with a unique battery monitoring algorithm to give you reliable and consistent runtime.

Thermal Engineering

LED lights get hot, that's a fact of life. One of our core principles is that we build our lights from the ground up to be able to handle the heat. Trail Evo in particular implements an industry-first pass-through cooling.

It is an incredibly unique feature that is enormously successful in keeping this high power lamp cool even on the hottest desert nights (looking at you Phoenix).

By collecting air through a built-in air scoop under the light, it then channels that cool air through fins that are directly attached to the LED's, and venting out the top of the light.

Thermal Engineering

High power bike lights get hot, that is why we use our engineering prowess to keep them cool.

Utilizing another industry first, we collect air through a scoop underneath the light, and pass it through the light, cooling all nine LED's that are spread apart to balance the heat load.
