A longboard is just a longer version of a skateboard. While skateboards usually have rounded ends, and are about two feet long, longboards sometimes have a rounded front end, and a tapering point at the back. Longboards are around four feet long. Skateboards are usually used for tricks, while the longboard is less suitable for tricks and is more of a crusing around the block kind. But, longhorns are better for riding, around the streets because they can go further with a peddaling than you can go with a regular skateboard. As for the wheels, bigger ones can go over bumps and cracks easier then smaller wheels. Smaller wheels can spin faster though. But bigger wheels can’t turn as sharply without rubbing the deck unless you have risers for them.
