Smart Bike Helmet with Turn Signals
Lumos Ultra is a sporty smart bike helmet made for daily commuting and recreational riding. A white front light, red rear lights and rear turn signals help you be seen from every direction, day and night. Lumos' own fit system keeps it stable and comfortable, and optional accessories (sun visor, winter liner, raincover and bug net) adapt it to every season.
Measure around the widest part of your head, just above the eyebrows and ears.
S and XL come in Mips only. M-L comes in Standard and Mips. The Lumos fit system fine-tunes the fit.
