Have multiple bikes? Want to swap Trail Evo or Detour between them often? Here ya go. (I can't believe we have to specify this, but this ONLY works with our lights, competitor lights will not be compatible.) Fits 35mm and 31.8mm handlebars. (shims for 22.2mm and 25.4mm are available) This can be mounted to the left or the right of the stem, so even if the mount is upside down, the light can be mounted right side up and function exactly as intended.

Want a helmet light that is actually a light designed for helmets? Not just a flashlight? Then you've come to the right place. Hangover borrows its name from the famous trail in Sedona, AZ (not the dreaded “brew flu”). Into it, we poured every ounce of our automotive optics knowledge, creating the most compact bike light anywhere. But slim does not mean dim. Some serious late-night thinking went into the Hangover, with countless hours prototyping the perfect beam pattern for trail riding and for helmet mounting. The resulting optics fills your entire field of vision with light, not just a narrow spot down the trail. So, you can avoid what you want to miss, and hit what you really want to shred. Good for 90 minutes of strong output, with the ability to charge on the go, and yet only 100 grams. USB-C quick charge 3.0 is included as standard. These lights are proudly and expertly made right here in Chicago, with the help of good coffee, homegrown talent, and a couple of dogs in the shop. Mounting Location: Helmet Application: Helmet light for all biking types (Mountain, Commuting, Road, Gravel) Runtime: (see runtime charts below) Charging: USB-C with Pass-Thru Charging (0 to 80% in 1 hour) Lumens: Approximately 1000 Battery Capacity: 3.6V 3500mah (12.6 Wh) Weight: Lighthead = 105g, Action Camera Mount = 20g Mode Runtime Adaptive 1.6 h (100 min) High 1.1 hr (72 min) Medium 2.9 hr (170 min) Low 6.5 hr (390 min) Daytime Strobe 6.5 hr (390 min) Nighttime Flash 3.0 hr (180 min)

Our original Road Edition set the bar high for the last several years. So we were challenged on how to improve it. Right away, we've ditched the large battery pack. This is all internal, self contained, USB-C rechargeable, and slim enough to fit in your pocket. Then we fine tuned the heck out of the beam pattern. Extremely smooth and progressive light field from the front of your tire all the way to where you are looking. We also added sidemarker lights to help with visibility from the side, much like on cars. We've incorporated our quick-release fiberglass-reinforced nylon mount that we, ahem, “borrowed” from those clever camera guys to keep everything pointing in the right direction and easy to put on and take off with one hand. We do have a custom mount solution to fit underneath most bike computers for that clean and tucked look, as well as non-round handlebars: Quick Release Action Camera Adapter Proudly and capably made just down the road in Chicago IL.

Behold the Trail Evo. Our flagship light, the sum total of our decades of experience designing automotive optics, all neatly wrapped up in the best bike light we have ever engineered. Think of this as harnessing the sun to your mountain (or gravel) bike. An amazingly wide beam pattern with a balanced carpet of light from the front of your tire to where you are looking. Giving you the sensation of riding in daylight. Zero wires, long battery life, USB-C rapid charging, simple interface, a robust and easy to install quick release mount. What more could you want? Backed by years of automotive lighting experience, built here in Chicago, IL, and a generous 3-year warranty (with an extended "don't-be-a-jerk" policy) that covers everything, including gnarly crashes, as long as you have a great story behind it!
