Before the first ride 

Before you mount your bike and enjoy your 
first ride please make yourself familiar with 
the instructions on the riding technique and 
the handling 

The seating position is essential for your 
riding comfort, well-being and efficient cycling 
on the recumbent bicycle. Therefor, you 
should adjust the frame, seat, handlebar and 
suspension to your individual requirements. 

In order to adapt the bicycle as closely as 
possible to your body dimensions and to find 
the ideal seating position you need to adjust 
the front boom, seat and handlebars. 

Get you bicycle adjusted with the help of your 
specialist dealer like described in "Adjusting 
your recumbent bicycle" on page 17.  

To ride this recumbent, you will have to make 
yourself acquainted with the different riding 
position. Make sure that you and all other 
future users of this bicycle will have read this 
manual carefully prior to the first ride. If you 
are in doubt, please consult your local dealer. 

Before the first ride the users of this recum-
bent have to practice and make themselves 
familiar with the different handling. We rec-
ommend to practice on a quiet road away 
from traffic. Before you ride the bicycle in 
traffic you must master the handling com-
pletely.  

Go to a road where you can ride straight 
ahead without being hindered. Hold your bike 
at the handlebars and pull a break. Then 
mount your bicycle and lean back. Leave one 
foot on the ground and put one on the pedal. 
Therefor rotate the crank in the top position 
so that you can pedal immediately with pow-
er.  

Try to keep your balance in that position. 
Assure yourself that you can stop whenever 
you want to and hold the bicycle with one 
foot on the ground. When you feel safe put 
pressure on the pedal, loosen the brake, pedal 

with a lot of force and immediately put your 
second foot on the other pedal.  

Do not care on which side of pedal you are 
currently pedalling in the beginning. Hold the 
handlebar loose but steady and accelerate 
with a few pedal strokes. Your bicycle needs 
speed to stabilise.  

Look ahead in the direction where you want 
to ride, not on the handlebar, at your feet, or 
the front wheel.  

In order to stop brake carefully with both 
brakes until the bicycle has come to a com-
plete stop. Only then do put a foot on the 
ground and keep the balance. 

 Danger! 

Never touch the ground 

with your feet while the bicycle is still 
moving. The feet could be caught on the 
ground and be pulled backwards which 
could lead to a serious injury. See also in-
formation about clipless pedals on page 15. 

 

 

Danger!

 With a compact recumbent 

like this it is possible that a foot of the rid-
er contacts the front wheel when riding 
sharp corners with a pedal in a low posi-
tion. You will have to avoid this situation at 
all times since in extreme situations it may 
lead to a fall and injuries.  

To control the bicycle you will have to apply 
the following cornering technique: when you 
ride a curve, stretch the leg on the inside of 
the curve, stop pedalling, only then start 
steering into the curve. Only when you ride 
straight ahead again should you resume pedal-
ling. Small riders should shorten the front 
mudguard to get more clearance.
