Indlela yokukhetha i-helmet efanelekileyo?

Ubungakanani kunye nokufaneleka: Isigcina-ntloko esifanelekileyo kufuneka singene ngokuqinileyo entloko, kodwa singaqini kakhulu. Kubalulekile ukulinganisa i-circumference yentloko kwaye ukhethe isigcina-ntloko esifanelekileyo ngokwemigaqo yobungakanani bomenzi. Imigangatho yobungakanani beempawu ezahlukeneyo zinokuhluka, ezinokufuna iinzame ezininzi kunye nohlengahlengiso xa kuthengwa.

Izinto eziphathekayo kunye nobunzima: Izinto zeehelmethi zihlala zibandakanya iplastiki ye-ABS, iifayili ezidibeneyo, iifayili zekhabhoni, njl. Izinto ezilula ezifana ne-carbon fiber zibonelela ngokhuseleko oluhle, kodwa ixabiso liphezulu kakhulu. Xa ukhetha, umntu kufuneka aqwalasele uhlahlo lwabiwo-mali kunye nenqanaba elifunekayo lokukhusela.

Ukungena komoya kunye nokuthuthuzela: Inkqubo efanelekileyo yokungenisa umoya inokuphucula induduzo yezigcina-ntloko, ngakumbi kwimozulu eshushu. Ukukhetha isigcina-ntloko esineendawo ezininzi zokuvula umoya kunye noyilo oluhle lokuhamba komoya kunokunciphisa ukugcwala. Nangona kunjalo, ukunyuka komoya kunokuchaphazela ingqibelelo yesakhiwo sesigcina-ntloko, efuna ukulingana phakathi koyilo kunye nokusebenza.

Qwalasela ukumila kwentloko: Abantu abavela kwimimandla eyahlukeneyo baneempawu ezahlukeneyo zokumila kwentloko, abantu base-Asiya ubukhulu becala benentloko ezingqukuva, ngoxa abantu baseYurophu beneentloko ezinde.

Amanyathelo amahlanu okukhetha isigcina-ntloko: Jonga inkangeleko kunye nelogo yemveliso, ivumba ivumba lesigcina-ntloko, yiva umaleko womqamelo, zama kwisigcina-ntloko, buza malunga nokusebenza kokhuselo lweentlobo ezahlukeneyo zezigcina-ntloko, kwaye uqinisekise ukuba ukhetha imveliso. ngophawu lwesiqinisekiso se-3C
