Radiobuttons i detta formulär?

Hallå på er.
Jag behöver ett enkelt kontaktformulär i PHP och sprang på detta.
Läste lite om det och det finns inget stöd för raidobuttons vilket vore bra för mig. Finns det möjlighet att få in det i denna kod eller finns det bättre sätt att göra detta på?

Är ute efter något enkelt formulär där besökaren kan fylla i lite fält samt välja bland lite olika alternativ...

Är jag ute och cyklar?

Ladda hem ett nytt kontaktformulär, för det där var otroligt fult skrivet.
