Handlebars
6.4.5.1 Replacing the handlebars
Not included in price
Handlebars are components that may be
§
replaced after approval by the vehicle or parts
manufacturer. Only handlebars that are
approved for use on e-bikes may be used to
replace the existing ones. Handlebars may be
replaced if the cable and/or line lengths do not
need to be changed. A change in riding position
is allowed within the original cable length.
Furthermore, the load distribution on the pedelec
changes considerably and may potentially lead
to hazardous steering performance.
Check handlebar width and hand position.
Have handlebars replaced at the specialist
dealer's if necessary.
6.4.5.2 Adjusting the handlebar width
The handlebar width should be as wide as the
rider's shoulders as a minimum. This is measured
from mid-point to mid-point on the hand contact
surfaces.
Figure 110: Determining the optimal handlebar width
The wider the handlebars are, the more control
they provide, although wide handlebars require
greater supporting force. Wider handlebars are
particularly useful to ensure a safer ride for loaded
touring bikes.

6.4.5.3 Adjusting the hand position
The hand is an optimal position on the handlebars
when the forearm and hand are in a straight line,
i.e. the wrist is not bent. In this way, the nerves are
not pinched and do not cause pain.
28°
Figure 111: Distribution of nerves with curved and
straight handlebars
The narrower the shoulders are, the greater the
bend of the handlebars should be (maximum 28°).
Straight handlebars are advisable for sports bikes
(e.g. MTB). They support direct steering
behaviour, but lead to peaks in pressure and
greater muscular strain on the arm and shoulder
muscles.
