Practical advice: Before riding the e-bike, sit on it and place your hands on the handlebars while letting
your feet rest on the ground. Apply the front brake firmly and move the entire e-bike forwards and
backwards. All the parts of the handlebars must remain firm, the headset should not wobble in any
direction (the handlebars should not jump backwards or forwards) and the front brake arms should hold
firmly. Apply the rear brake in a similar manner and check the stability of the brake attachment. This tests
the entire handlebar assembly and the components of the brake system.

The stem is attached to the fork tube from the outside. The play in the headset in this type of stem is
adjusted using a screw at the top of the stem. This screw is connected to the fork neck using a so-called
“star socket”, which is impressed into the fork neck. The play in the headset can be adjusted only once
the main socket screws on the side of the stem have been loosened. When adjusting this assembly,
proceed as follows:
In this case you can only adjust the height of the handlebars
downwards, by removing the spacing rings from under the stem and
reducing (cutting) the fork neck to the required length. You must leave
reduction of the fork neck to a specialised servicing facility. If you want to
raise the handlebars, you either have to choose different handlebars or a
stem with another (higher) angle.
The main adjusting elements of this type of stem are:
1. Lateral screws 2

2 – levelling the stem in a linear direction.
