Some scooters come with telescopic stems that can be adjusted to suit your height (the same way you’d adjust a seat on a bicycle). However, for models that don’t have this feature, the only way to make your handlebars higher is to use a riser.
Handlebar risers can increase the height of handlebars by 2 to 4 inches. There’s a catch, though – they can only be used on scooters where there’s an existing bracket holding the handlebars in place. And, the riser needs to have been specifically built for your scooter.
They work by slotting between the opposing ends of the handlebar bracket, thereby making the bracket, and consequently, your handlebars, taller.
