What is the optimal handlebar height for kick scooting?

When riding a kick scooter, you should stand upright with your arms almost fully extended to comfortably hold the handlebars. For adult riders, the handlebar height should be at least 40″ (100 cm), and 2-4″ (5-10 cm) higher for taller riders. Boardy’s handlebar can be adjusted up to 108 cm, making it suitable for riders as tall as 6’7″ (200 cm).
