6 Troubleshooting

6.1 Limitation areas — Troubleshooting
When adjusting the centre of gravity, some settings can cause
limitations in some positions. This can happen for example when
adjusting the:
•

Seat tilt

•

Seat depth

•

Backrest recline

The following sections will give some examples of the possible
limitations, but also suggestions about solutions.
6.1.1 Seat tilt
A
B
When the seat is tilted, the backrest attachment A can collide with
the rear wheel axle B or the rear wheel attachment C.
Possible solutions:
• Move the rear wheel attachment C further backwards.
• Turn the rear wheel attachment C in order to have the rear
wheel positioned further backwards.
•
Choose the low mounting position for the rear wheel attachment
C.
This will increase the seat height, to compensate, use
a longer front wheel fork.
•
Use the tilt reduction bushing A in order to avoid the limitation.
The seat tilt will have slightly reduced angling
possibilities.
6.1.2 Seat depth
When the seat is tilted, and the seat plate D is adjusted in depth,
the seat plate D can collide with the rear wheel axle B or the rear
wheel attachment C.

Possible solutions:

C
6.1.3 Backrest recline
When the backrest is reclined, the backrest tube E can collide with
the rear wheel axle B or the rear wheel attachment C.
Possible solutions:
A
• Move the seat plate D forwards to increase the seat depth.
• Move the rear wheel attachment C further backwards.
•
Turn the rear wheel attachment C in order to have the rear
wheel positioned further backwards.
•
Choose the low mounting position for the rear wheel attachment
C.
This will increase the seat height, to compensate, use
a longer front wheel fork.
• Use the tilt reduction bushing A in order to avoid the limitation.
The seat tilt will have slightly reduced angling
possibilities.
•
Move the rear wheel attachment C further backwards.
• Turn the rear wheel attachment C in order to have the rear
wheel positioned further backwards.
•
Choose the low mounting position for the rear wheel attachment
C.
This will increase the seat height, additional measures
may have to be taken into consideration, for example to
use a longer front wheel fork.
•
Use the tilt reduction and / or the backrest recline reduction
bushing A in order to avoid the limitation.
The seat tilt and / or the backrest recline will have
slightly reduced angling possibilities.
See section: "Tilt and / or backrest recline reduction" for
information about the tilt reduction.
