3.3 Tyres and hoses
The tyres of the therapy bicycle must always
have enough air pressure, as otherwise the
tyres could puncture and the rims get da-
maged or the driving behaviour is negatively
aected. The optimal tyre pressure is marked
on the tyre casing (A). If the tyre tread only
depresses slightly on being pressed forcefully
with the thumbs, the tyre pressure is correct.
For exact values, use a pressure gauge!
Check all tyres regularly and replace them im-
mediately in case of damage or wear!
3.4 Chain tension
Due to the elongation of the chain caused
by use, the chain tension must be checked
regularly. Check the chain tension by testing
whether the chain of the therapy bicycle can
be pushed max. 10 - 15 mm up and down.
To tension the chain, remove the stabiliser
frame (B), loosen the axle nuts (C) using a
15mm open-end wrench and pull the rear wheel (D) towards the back uni-
formly on both sides. If the therapy bicycle is equipped with a gear hub
(3 or 7 gears and idle brake hub), you must also disassemble the brake
anchor and the click box of the gears. Leave this work to your specialist
dealer in case of any uncertainty!
After each adjustment, please retighten all screw connections!
An incorrectly-tensioned chain can lead to increased wear!
3.5 Light system / dynamo
Side dynamo: The lighting system is acti-
vated by pressing the switch (E) of the side
dynamo. The dynamo roller then lies
automatically against the tyre flank.
Hub dynamo: The hub dynamo is automati-
cally integrated into the wheel and is swit-
ched on via the switch (F) on the headlight.
