The perfect accessory for the daily commute, the Giro Ethos Mips bike helmet features a lightweight in-mold design with built-in front and rear LED lights and remote handlebar-activated turn signals.


  • Features front and rear integrated and rechargeable LED lights—2 white "be seen" front lights and 2 red rear lights for substantially increased visibility to drivers
  • Handlebar-mounted remote controls the front and rear lights, allowing you to select solid or flashing modes, change brightness levels and activate the turn signals easily
  • With their bright amber flashes, the integrated turn signals speak the common language of traffic, broadcasting your intended path to other road users
  • Entire system is USB-C rechargeable with an estimated run time of 10 hrs. in low-blink mode and 5 hrs. in the high-blink mode; delivers 45 lumens front and 30 lumens rear
  • Helmet and remote can be fully charged in just 2 hrs. and 1 hr., respectively
  • Integrated Mips® Brain Protection System helps reduce rotational forces while enhancing fit and comfort by combining the Mips slip plane with the adjustable fit system
  • In-mold construction keeps the weight manageable; full hardbody coverage adds durability
  • IONIC+® Padding Pure Silver is the secret ingredient that gives IONIC+ the power to provide natural, permanent odor protection to keep your helmet feeling fresh
  • Roc Loc® City Mips fit system features a rubberized dial for easy adjustability and large plush pads for ultimate comfort and stability
  • Fit system is made of a durable flexible material for long-term performance and daily use; 3 positions of vertical adjustability and 2.4 in. range create a perfect fit
  • Reflective threads are strategically woven into the helmet retaining straps for an added element of visibility
  • Features a TPU soft rubber waterproof brim


To find your size, position a tape measure just above your ears and about 1 in. above your eyebrows. Keep the tape level to measure the circumference around the largest part of your head and then find the corresponding size in the Technical specs info.
