You can place the dock where you want on the handlebar with the only constraint of your security. Choose the location of your HAIKU and fit the dock in the right place by pulling the strap tight on itself. Be sure to have the rubbered layer in contact with the bar.
HAIKU has to be oriented depending on its screen (you can set it up in the app settings). Then your dock have to be placed the right direction (corresponding to the display).
HAIKU is delivered with three straps of different length. The small one should fit all handlebars, the medium one is made for stems and covered bars and the large one is made to cover plastic fairings.
