Horizontal saddle adjustment
Check the horizontal position of the saddle by
turning the pedal to its forward position, while keep-
ing the pedal horizontal; place your foot onto the
pedal (while sitting in the saddle). (Fig. 2)
The saddle is positioned correctly if the lower leg is in
a vertical position. If that is not the case, loosen the nut
(Fig. 2-A) and reposition the saddle backwards or for-
wards and retighten the nut.
2.7 Handlebars
The handlebars can be height-adjusted according to
your needs.
Loosen the clamping spindle (Fig. 3-A) and adjust the
handlebar uprights (Fig. 3-B) to the desired height.
Lightly tapping a hammer on the head of the spindle
helps adjusting the handlebar uprights. Retighten the
clamping spindle when the handlebars are properly
adjusted. (Fig. 3).
You can tilt the handlebars as desired by loosening
the clamping screw (Fig. 3-D).
Fig. 3
Once the desired position is reached, retighten the
clamping screw. The tilt angle of the handlebar up-
rights can be adjusted by loosening the clamping
screw (Fig. 3-E). An adjustment here will change the
distance between saddle and handlebars, as well as
the grip height. Make sure to retighten all screws
when nished.
Before you take your trike on the road
Danger!
Ensure that the minimum insertion depth marker (Fig.
3-C) on the handlebar uprights remains inside the
steering head and is not visible!
2.8 Pedals
Robust, non-slip pedals are mounted as standard.
2.9 Tire pressure
Your driving enjoyment will be optimised with accurate
tire pressure.
Overly hard tires will not be able to cushion small
bumps in the road surface and can therefore diminish
drive safety. Overly soft tires will make pedal resist-
ance harder. You will tire yourself out needlessly.
Excessively low pressure will damage the fabric of the
tire and therefore increase wear.
Your tire pressure is correct if the side of the tire or
the tread is barely impressed when squeezed with a
thumb. Remove the dust cap from the tire valve. Press
the air pump tightly against the valve and pump up
the tire. Don't forget to replace the dust cap when
nished. Where provided, the white re ector strip
along tthe tire anks replaces the spoke re ectors.

For optimised driving comfort, the vehicle suspension
should de ect by about 30% with the user seated in
driving position. You can adjust the sus pension
tension by manually turning the pro led adjustment
ring on the threaded part of the suspension element.
