The ABUS Urban-I 4.0 Silver L has a magnetic rear light, so you stand out even more when you're biking. You can detach the light strip and easily charge it. The sun visor protects your eyes from sunlight and rain. You can choose whether you place the visor on the helmet or not. That way, you can decide not to use it in the dark, for example. Thanks to the opening in the back, you can also wear the helmet with a braid, bun, or ponytail. You can quickly open the buckle under your chin with 1 hand thanks to the magnetic closure. The helmet fits on a head circumference between 57 and 61cm.
