Helmets are not obligatory to wear in Croatia. However, we HIGHLY suggest wearing one while riding. Besides safety protection it also provides sun protection and it can get hot during summer months in Croatia. Helmets are not included in the bike rental price and we provide them at additional fee. Our helmets have CE-EN 1078 standard and come in 3 different sizes: child, small/medium (52-58) and medium/large (58-62).
