chain and remove super uous oil with a lint-free
cloth. This will ensure that the chain is only lubricated
where it is needed. A very dirty chain will not only soil
your clothes, but will also diminish its effectiveness.
Caution!
All loosened screw connections must be carefully
retightened after the axle housing has been aligned.

2.15.1 Chain tension in tandems

Tensioning the transmission chain via the cam:
The transmission chain is tensioned properly if it can
be pressed down with the thumb at its midpoint by
about 12 mm.
The tension can be adjusted by way of a cam under-
neath the frontal bottom bracket housing. Loosen the
screw under the cam housing of the frame. Use an
adjustable cup wrench to turn the cam in drive direction.
Make sure that the cam sits centred in its housing.
Then tighten the screws again (observe the max.
torque value of 8 Nm!). Excessive torque could damage
the thread of the cam housing.
Caution!
Excessive chain tension will result in an unpleasant
cracking and could cause the transmission chain to
tear. Insuf cient tension can cause the chain to jump
out of gear. Turn the cranks in free wheeling direction
and look out for proper tension and atypical noise.

2.16 Initial test drives

Now that you have familiarised yourself with the var-
ious operating elements of your new trike and have
adjusted the components to your body weight and
height, it is time to take your rst drive.
But be careful:
A trike has completely different driving character-
istics than a traditional bicycle (with two wheels)!
The difference in behaviour is particularly apparent in
curves:
Before you take your trike on the road

Never try to lean out of a curve! That would be
wrong, as a trike reacts differently than you might
expect: The wheel innermost to the curve will
threaten to lift off! In other words: never lean out of
the curve, but instead into it!
Please remember that you will have to experiment
with your new trike regarding its driving be-
haviour (speci cally in curves) in the presence of
a second person before you take your rst drive
on your own.
Always drive curves as slowly as possible!!! Please also
remember that the widest point of your trike is
behind or in front of you. Practice your driving with
appropriate obstacles to learn judging the width of
your trike and to not get stuck or damage anything,
once you take your trike on the road.
