Cateye say
Compact design. Replace on-the-fly cartridge battery. Handlebar or helmet mount. Optional fast-charging cradle. We kept everything you love about our game-changing Volt300, and made it brighter. With 400 lumens and 5 modes, the Volt400 lets you see and be seen during your dawn and dusk commutes, and makes training after hours an option again.
