You longboard can not survive without great wheels. Its like a car without tires.
Your car can not move without wheels/tires and the wider the are the more contact with the asphalt.
Same is true for longboards. They have wider wheel based – compared to skateboards – so there is more contact with the concrete/asphalt you skate on.
This allows for sliding at higher speeds and keeping the board under control at high speeds.
On a drop deck longboard you are close to the ground and you have a stable ride, however without the right wheels you still go no where.
Here a great drop down longboard with premium zaza wheels size 70mm with a 83a hardness.
This is a great freeride / small downhill longboard from ehlers.
