Usually, yes. If your integrated bar has an accessory fitting on the front or underside (Trek RSL with Blendr, Roval Control, most Scott Syncros IC bars with the two threaded holes), we have a mount that attaches there. If the bar has no mounting features at all, email us with your bike model and we'll tell you honestly what works and what doesn't.

For round bars, the stock mount fits 35 mm and 31.8 mm. Shims for 25.4 mm and 22.2 mm are in Accessories.

Portal uses a standard GoPro-style mount interface, so any action-camera mount works, including third-party strap mounts. Portal ships with a curved adhesive base that fits most trail and enduro helmets. Wide and notched bases are available for helmets with a flat centre section or a screw-in mount boss (Smith Forefront, some Giro). On a full-face, the stock base usually sits on the visor, or use the wide base on the shell behind it.

Not sure? Email us a photo of the top of your helmet and we'll tell you which base to use.

Depends on the mode. In adaptive mode both lights run about 2.6 hours from full to the low-battery warning, measured on the bench at riding-speed airflow. Trail Evo does 1.7 hours on high, 4.2 on medium, 8.5 on low. After the warning you get roughly 20 minutes at a get-home level. Full curves for every mode on both lights are in the Runtime section above.

Yes. Both lights pass-through charge in every mode. Plug the bank in from the start of the ride, not when the light is dying, and it charges while you go. A QC 3.0 or better bank keeps up with high output. A low-power USB source like an eBike display port will slow the drain but won't stop it.

Any USB-C charger, anywhere in the world. Your phone brick works. A QC 3.0 or better charger is fastest: Trail Evo goes 0 to 80% in about 3 hours and Portal in about 2 hours, then both trickle the last 20%. C-to-C cables work fine; a C-to-A cable is in the box and a C-to-C is available.

Yes. Both lights are sealed for rain, snow, creek crossings, and a hose-down after the ride. We don't sell them on an IP number; we build them for wet trails and if you somehow manage to drown one, it's covered. Don't pressure wash them, and dry the USB-C port before charging.

Runtime drops below freezing, same as any lithium cell. We route waste heat from the LEDs to help keep the cell warm, which helps on higher modes. On low there isn't enough heat to matter, so expect shorter winter runtimes. Keep the light indoors until you roll out.

Trail Evo: 2200 high, 880 medium, 440 low. Portal: 1650 high, 500 medium, 250 low. We don't lead with lumens because a single number tells you nothing about where the light goes. Beam pattern is what you actually see on the trail. There's more on that in the Runtime section.

We ship worldwide from Chicago. Duties and taxes are set by your country and shown at checkout before you pay. If you're in the UK, EU, Australia, or Canada, check the shop locator first; a local dealer may have them on the shelf.

One sale a year, around Black Friday, and it usually sells out. No free-shipping promos, because we won't undercut the shops that stock our lights.

Only through a USB output. Most eBike display ports are low power, so they slow the drain rather than power the light. A dedicated wired eBike light is in development.

Yes, but not in the field. If a cell ever wears out, send it in and we replace it under warranty.

Three years, plus lifetime support from a real person in our Chicago shop. We cover crashes, chewed cables, and the light rolling out of the van and getting run over. Just be honest about what happened so we can engineer the failure out. Full details on our warranty page.
