A good hint is to choose a bar with the same width as your shoulders. If you`re mostly into technical tricks like barspins, choose a narrow bar. And if you`re more a big air and no hands tricks rider, then choose a wider bar. (Remember you can always choose a wide bar and cut it to your preference! )HeightStunt scooters are usually lower than standard scooters. Choosing a height is also a matter of preference. Skilled riders often choose lower bars to gain stability and better control. A tip when choosing the right height is to make sure the bar reaches somewhere between your thighs and hip. Avoid making your bar wider than its height as this is considered unstylish by skilled riders and can be uncomfortable for transportation.ThreadIf choosing a bar with thread you should also have a fork with thread.
