Revo 5 Dynamo Light

What Our Gearhead® Experts Are Saying:

"I set this up on my winter training bike with a dynamo hub and stopped thinking about light runtime entirely, since Program 2 held a constant 1700 lumens no matter how hard I was pushing the pedals. On a 200k ride that started before dawn, I never once worried about the battery dying halfway through."

We built the Revo 5 around a simple compatibility question: any AC dynamo hub, paired with a 1600mAh internal battery, means output that scales with effort instead of running down. Program 2 holds a fixed lumen count for predictable group rides, while Program 1 prioritizes charging the battery and topping off a phone or GPS through USB-C once output stabilizes above 40 percent. A 12° spot beam and 2000 lumen ceiling deliver over 50 meters of throw at speed, and the IP68 and IK09 ratings mean the hard anodized aluminum housing holds up through submersion, impact, and long winter seasons on the bike.
