Handlebar mounting is done with very slick strap that can be tightened based on the rider’s preference. The same strap is used for standard and oversized handlebars. At first we found the strap too long and found the excess bothersome but we realized we can loop the strap back  in the pin and tuck it neatly. It can be aimed left to right.
