Bright, Sleek, and Respectful to Other Road Users
The Portland Design Works Kepler E-bike Headlight combines serious illumination with thoughtful engineering. Constructed from aluminum alloy at just the right size for a clean look, this headlight delivers 350 lumens of powerful output while maintaining excellent visibility without blinding oncoming traffic. The precision lens features a European standard beam pattern—a vertical cutoff design that focuses light onto the path in front of you rather than scattering it everywhere. This approach is more respectful to pedestrians and other cyclists while providing superior road illumination, and riders who experience this beam pattern quickly come to appreciate its effectiveness.
Designed specifically for e-bike integration, the Kepler works with any 6V-15V e-bike system and powers directly from your bike's electrical system. It comes equipped with a pre-installed Bosch-friendly plug for quick, plug-and-play attachment to any Bosch e-bike system—no electrical expertise required. For riders with other e-bike systems, the Bosch plug simply clips off and the light functions identically when directly wired. The headlight includes both a sturdy stainless steel fork mount and handlebar mount, giving you installation flexibility. With a 55-inch cable and robust OSRAM Power LED, the Kepler is built to handle daily commuting, urban exploration, and all-weather riding with consistent, reliable performance.
