The XSV lighting system (G2.1) offers unmatched light output and performance. By combining the brightest Gloworm light head with a powerful 10,000-mAh rechargeable battery, it delivers 2 hours of runtime at maximum power and more than 12 hours at 20% power (720 lumens). Thanks to its compact design and versatile mounting options, you can position your light exactly where you need it. The XSV will revolutionize the way you ride at night.
The G2.1 is an evolution of the G2.0 series and features an improved integrated power cable system with a lockable 3-pin connector, which offers superior durability and a secure, weatherproof connection compared to the previous standalone USB-C cable of the G2.0 series. You continue to benefit from the advantages of USB-C fast charging (PD), now with added reliability for demanding riding conditions. We’ve optimized the accessory kits based on rider feedback, so your light comes pre-configured for your specific mounting needs and includes everything you need to hit the road right away.
Compatible with electric bikes featuring a USB-C PD output port (e.g., DJI Avinox and others) via the separately available 3-pin to USB-C cable (G2.1), allowing the light to draw power directly from the electric bike's rechargeable battery when available.
Mix, match, and reconfigure. Every G2.x rechargeable battery, cable, mount, and accessory works seamlessly with the G2.0 and G2.1 light systems, so you can switch between bikes, change setups in seconds, and expand without having to start from scratch. Add the 3-pin to USB-C cable (sold separately) and draw power directly from any electric bike with a USB-C PD output port, including the DJI Avinox.
