Bicycle, Bicycle with a Motor, Or Motorcycle...
Bicycle Helmet, E-Bike Helmet, Motorcycle Helmet...
I personally think a well secured Mountain Bike Helmet to start would be best for you.
Further Note: I am not a supporter of "Mandatory Helmets" for adults, but I would not ride without one anymore...
