What is the best for a motorised skateboards?.
The main difference between a short board and a long board besides for the length is the wheels. A short board is designed for tricks and is much easier when doing complicated jumps and technical spins with the board, the board is normally going to have smaller and harder wheels the hard wheel allows the wheels to slide easier on hard surfaces.
A long board is designed for travel and the wheels are softer and larger for a smoother ride that is perfect for electric skateboards especially when travelling at high speeds. That softness of the wheel helps the board ride over cracks, bumps and rocks on hard surfers a lot easier. It will be much smoother ride. It is going to grip the ground a lot better so your board wont slide. for the smooth stable feel when you’re riding that is very important when doing high speeds on a electric skateboard. The length of the board also gives the board more stability.
